Sustanon

Sustanon is without question the most popular testosterone mixture on the planet. Where most testosterone compounds are single ester compounds, Sustanon 250 is comprised of four distinct esters; four distinct testosterone compounds conjoined into one. Developed by Organon for the purpose of infrequent Testosterone Replacement Therapy (TRT) treatment, while effective it would soon be held as vital to many performance enhancing athletes; after all, Organon has for years manufactured some of the best anabolic steroids on earth.

When it comes to Sustanon's original intent, the idea was to create a testosterone compound comprised of varying sized esters that would allow for instant testosterone benefits that would be long lasting. Of course, this hope would prove to be successful; in-fact, a TRT patient could actually remedy his low testosterone condition with only one injection of Sustanon 250 every three to four weeks. Even so, due to a mixture of small and large esters, a problem was later discovered; while low testosterone would be remedied, total testosterone levels would rise and fall beyond appropriate or satisfactory means. For this reason, if levels are to be maintained at a more stable level, one injection every teen to fourteen days is probably more efficient, and for this reason, many U.S. physicians often opt for large single ester testosterone compounds likeTestosterone Cypionate.

While the original intent of Sustanon was for TRT, this can be an excellent choice for performance enhancing athletes; after all, Sustanon 250 is merely testosterone. Even so, due to the mixture of four varying esters, if levels are to remain not only stable but also peaked at all times, despite large esters being a part of the compound every other day injections are normally recommended. You might be able to get by with three injections per week, but an every other day schedule will prove far more efficient. With all of this in mind, we want to look at Sustanon , what it is precisely, what it has to offer, the side effects associated, and of course, what you can do about them in-order to achieve successful supplementation.

Sustanon Traits & Nature:
As stated above, Sustanon is a four part testosterone mixture; specifically it is comprised ofTestosterone Propionate, Testosterone Phenylpropionate, Testosterone Isocaproate and Testosterone Decanoate. Through this mixture, the Propionate and Phenylpropionate esters represent the small esters and will provide fast acting testosterone benefits while the Decanoate ester, a truly massive ester will ensure the benefits are long lasting; the Isocaproate ester fills the role in the middle. Of course, its not enough for these esters to be conjoined together, in-order for Sustanon 250 to exist they must be conjoined together in a precise manner; otherwise, it is not Sustanon 250.

The precise composition of Sustanon is as follows:

• 30mg/ml Testosterone Propionate
• 60mg/ml Testosterone Phenylpropionate
• 60mg/ml Testosterone Isocaproate
• 100mg/ml Testosterone Decanoate

If you come across a product claiming to be Sustanon, if it is not comprised exactly as listed above, if it carries varying esters or even the same esters at different doses it is not Sustanon 250; the above is what defines and separates this testosterone form. As a testosterone compound, in many ways everything that can be said of all single ester testosterone compounds can be said of Sustanon; in the end, it all comes down to personal preference. At any rate, as a pure testosterone compound, Sustanon carries an anabolic and androgenic rating of 100 in both categories, and is a highly versatile steroidal hormone. Identical to the testosterone you naturally produce, Sustanon 250 carries all the sexually related traits and plays intrinsic roles on our sexual and physical health and to a degree even our general state of mind and overall well-being.

A compound that has the ability to greatly enhance protein synthesis, this is important as protein is the building block of muscle tissue and synthesis represent the rate by-which cells build proteins. Further, Sust as its often called will enhance nitrogen retention in the muscle tissue; all lean muscle tissue is comprised of 16% nitrogen, and the more we retain the more anabolic we remain; our anabolic atmosphere is enhanced. While these two factors are primary and important traits, Sust is not done yet. Often ignored but truly valuable is this hormones ability to increase the production and release of Insulin-Like Growth Factor-1 (IGF-1). IGF-1 is highly anabolic, a peptide hormone produced by all human beings and it plays important roles revolving around our total recovery; in-fact, IGF-1 will affect nearly every cell in the human body.

Enhanced protein synthesis, nitrogen retention and IGF-1 are all important factors, but Sustanon continues to not disappoint. Through supplementation, red blood cell count is increased, and as red blood cells carry oxygen to and through the blood this results in greater blood oxygenation. Then we have glucocorticoid suppression; simply put, the suppression and reduction of stress hormones. These nasty hormones, cortisol being the most well-known are in many ways the opposite of anabolic hormones in that they destroy muscle tissue and promote fat gain; Sustanon will see such hormones suppressed.

A hormone that aromatizes heavily, like all testosterone compounds Sustanon 250 can lead to adverse estrogen effects. Further, due to its heavy androgenic activity, this is a steroid that cannot be recommended to women or virilization will occur. Absolutely, women need testosterone, and they can suffer from low testosterone, but if therapeutic treatment is needed a single ester compound is easier to control. As for performance enhancement, the doses necessary to promote such performance will always lead to some level of virilization and on this basis other steroids must be chosen; specifically steroids that possess low androgenic activity and low virilization ratings.

Testosterone ReplacementTherapy Benefits of Sustanon:
When it comes to Testosterone Replacement Therapy, the benefits of Sustanon are fairly straightforward; your testosterone levels are low, Sust is pure testosterone, and through administration the problem is solved. Through supplementation, each and every last symptom of low testosterone can and will be reversed, and as a result, your overall quality of life enhanced. Those who suffer from low testosterone often find their libido is severely diminished and often erectile dysfunction becomes a problem, but these are hardly the only symptoms. A loss of muscle mass and strength is often common as is increased body-fat, and this can all occur despite proper exercise and dieting habits. Further, those who suffer often find their energy levels drained, they become depressed, suffer from insomnia and their immune system weakens; not to mention they suffer from a lack of mental clarity and open the door to many far more serious conditions. When low testosterone is ignored, it has been shown to be a contributor to leading to diabetes, osteoporosis and even Alzheimers disease. Thankfully, if you suffer from low levels, Sustanon 250 can ensure you suffer no more, and the odds of you falling prey to the more serious conditions will be greatly improved.

Performance Benefits of Sustanon:
In many ways, there is a lot of crossover as it pertains to TRT and performance based supplementation of Sustanon, but in this case, were referring to supraphysiological doses. In a TRT plan, we are supplementing with testosterone in-order to bring our levels back to normal, but with performance the idea is to increase them beyond what can normally be achieved in-order for more testosterone to be available to do what testosterone does best. In any case, when it comes to the performance benefits of Sustanon 250, they can largely be broken down into three categories, bulking, cutting and overall enhancement.

• Bulking: with supplementation and adequate calories present, you will be able to gain more lean mass as well as see your strength increase. Further, due to the metabolic enhancing properties of testosterone, you will be able to do so with less body-fat accumulation that normally accompanies mass gaining phases.
• Cutting: when it comes to the cutting cycle, many often think of other steroids before they think of Sustanon or any testosterone compound, but exogenous testosterone can be essential to a successful plan. Through use, you will ensure you preserve as much lean tissue as possible while calories are restricted, and this is invaluable. When we diet, in-order to lose body-fat our caloric intake must be at a deficit level; we must burn more calories than we consume in-order to burn body-fat. As a result, lean tissue is often lost, but Sust will protect it, and the more lean tissue you hold onto the more fat you'll burn. Couple this with testosterones metabolic enhancing properties and you're a fat burning machine.
• Overall Enhancement: regardless of your purpose of use, bulking, cutting or to simply enhance athletic performance, you will find Sustanon is one of the most versatile steroidal compounds on earth. Regardless of your purpose of use, your muscular endurance will be enhanced as will your overall rate of recovery, and those two traits alone make this a steroid worthy of consideration. When we look at all these benefits and how testosterone affects the body in its every day functional sense, the benefits of Sustanon 250 as you can see are truly vast.

The Side Effects of Sustanon:
As a heavily aromatizing steroid, the primary side-effects of Sustanon 250 will be those of an estrogenic nature as the aromatase process refers to the conversion of testosterone into estrogen. As estrogen levels increase, this can lead to gynecomastia and excess water retention, which can in-turn promote high blood pressure. For this reason, its often advised that the use of an Aromatase Inhibitor (AI) be present with the use of any testosterone compound;Anastrozole (Arimidex) and Letrozole (Femara) are always your best choices. By their natural mode of action, AIs will inhibit the aromatase process from occurring and even lower the bodys total estrogen levels; problem solved. It should be noted; Selective Estrogen Receptor Modulators (SERMs) can also protect against gynecomastia by binding to the receptors in the place of estrogen; however, they will not inhibit aromatase or reduce estrogen levels. This means SERMs cannot offer protection beyond gynecomastia, and depending on your dosing and overall sensitivity they may not be enough to protect you from that; AIs are the only true answer.

While AIs can offer a lot of protection, and with supraphysiological doses of testosterone they're often recommended, they can have a negative impact on your lipid profiles as can supraphysiological doses of testosterone to a degree. Its not uncommon to see LDL levels increase and HDL levels decrease, but all hope is not lost. For this reason, it is imperative you do not supplement if you have high cholesterol, but if healthy you should give extra effort into ensuring the continuation of such healthy levels. A great place to start is with the consumption of plenty of omega fatty acids as they will increase your HDL levels, which will in-turn regulate your LDL levels.

Notes on Sustanon Side-Effects:
You should not supplement if you have high blood pressure.
You should not supplement it you have high cholesterol.
You should not supplement if you suffer from prostate enlargement.
You should not supplement if youre not a healthy adult male.
Weve already looked at blood pressure and cholesterol, and while prostate enlargement is unlikely with testosterone use, it is possible, and the problem could be exasperated if you already suffer. The testosterone hormone has the ability to convert into dihydrotestosterone (DHT), the androgen that causes prostate enlargement, but it takes a massive DHT buildup for a healthy prostate to fall prey. Further, DHT buildups of a massive nature can induce hair-loss in men who are predisposed to male-pattern baldness; however, if you are predisposed you were going to lose your hair anyway.

It must be noted; when it comes to the side effects of Sustanon 250, TRT patients rarely have a large concern; after all, theyre merely replacing, they are not enhancing. With TRT level doses, we are not presenting a hormone we are unfamiliar with or surpassing levels our body is unaccustomed to; once again, we are merely replacing what we are lacking with a hormone we are very familiar with. Then we have adolescent use, and in no way can such use be recommended unless under severe therapeutic need due to the damage it could cause to a fragile and underdeveloped androgen system.

Making a Purchase of Sustanon:
If you decide to buy Sustanon for the purpose of performance enhancement, in many cases, especially if you live in the U.S. youll be doing so on the black market, and this compound comes with a cost with such a purchase. First and foremost, this is one of if not the most expensive testosterone compounds youll ever find; this is largely due to is extreme popularity. Further, this is without question the most commonly counterfeited testosterone compound youll ever find. In most cases, when counterfeited its still testosterone, but its normally a single large ester testosterone compound and not the precise four ester mixture as described above. For these reasons, if you decide to buy Sustanon 250, youll need to put in a little extra effort if youre going to find a good price, and more importantly, if youre going to find a quality product. Make no mistake, theres plenty of high quality product at a reasonable and fair rate, but you may need to do a little digging.

Testosterone Enanthate

Testosterone Enanthate is probably the most commonly used form of testosterone by both athletes and bodybuilders alike. Further, in the United States and in Algeria, it is one of the most commonly prescribed testosterone compounds for the treatment of low testosterone or andropauseconditions; however, Testosterone Cypionate is the most commonly prescribed when an injectable form is offered. Extremely effective for building muscle and enhancing strength,Testosterone Enanthate can also help with losing fat and it comes with some great news; its very cheap and widely available.
In-order to understand exactly how Testosterone Enanthate (commonly referred to as "test-e") builds muscle and burns fat, first well take a look at androgens and what they do in the body. You see, hormones are substances secreted by one cell that has an effect on the functions of another cell. Testosterone is manufactured in the Leydigs cells of the testes (in men) and the adult male produces between 2.5 and 11mgs of Test per day.
Testosterone induces changes in shape, size and also can change the appearance and the number of muscle fibers(7). Androgens like testosterone, which is exactly what Testosterone Enanthate is can protect your hard earned muscle from the catabolic (muscle wasting) glucocorticoid hormones(8), thus inhibiting their ability to send a message to muscle cells to release stored protein. Remember, testosterone sends a message to muscle cells to store more contractile protein (called actin and myosin); glucocorticoid hormones send the opposite message. In addition, Testosterone Enanthate has the ability to increase erythropoiesis (red blood cell production) in your kidneys(9), and a higher Red Blood Cell (RBC) count will improve endurance via better oxygenated blood. More RBCs can also improve recovery from strenuous physical activity. Of course, aggression levels can rise dramatically with the use of exogenous testosterone (15); however, its important to remember aggression in of itself is not a bad thing; what we do with it is what makes it right or wrong. At any rate, Testosterone Enanthate holds no mind altering traits or nature whatsoever.
All of these great benefits are to be had with the use of Testosterone Enanthate alone, but realistically, it will in most cases be part of a cycle containing one or more othersteroids. People who are bulking will probably choose Deca Durabolin or Trenbolonecompounds, and of course the possibility of powerful oral steroidslike Anadrol or Dianabol. Then we have those who are cutting, and they will probably steer towardsEquipoise and once again Trenbolone, along side compounds such as Anavar, Masteron, Winstrol and perhaps Primobolan; all are solid options. Very often users will administer Testosterone Enanthate once or twice a week, but blood levels are still above baseline with this steroid at around day eight (16).Common wisdom holds that the testosterone portion of any such cycle should be equal to or greater than any other injectable steroids portion (on a mg basis); however, this isnt always needed, but its a good rule of thumb to ensure no low testosterone condition exists.
As you may have suspected, Testosterone Enanthates anabolic/androgenic effects are dose dependent; the higher the dose the higher the muscle building effect(10). Lets take a look at exactly what kind of results we can expect from administration of Testosterone Enanthate:
Effects of 20 weeks of GnRH agonist plus Testosterone Enanthate administration on relative changes (mean SEM) in total LBM (A), appendicular LBM (B), and trunk LBM (C) (percent change from baseline) measured by DEXA. P values are results for ANOVA: *, P < 0.05 vs. all other dose groups for the multiple comparison tests using Student-Newman-Keuls; a, P < 0.05 vs. zero change.(11)



This chart shows that the subjects in this test made a roughly 15% gain in Lean Body Mass from 20 weeks of 600mgs/week of Testosterone Enanthate. That's pretty impressive, but the following set of charts is even more telling:



Change in fat-free mass (A), fat mass (B), leg press strength (C), thigh muscle volume (D), quadriceps muscle volume (E), sexual function (F), insulin-like growth factor I (G), and prostate-specific antigen (H). Data are means SE. *Significant differences from all other groups (P < 0.05); significant difference from 25-, 50-, and 125-mg doses (P < 0.05); +significant difference from 25- and 50-mg doses (P < 0.05); and significant difference from 25-mg dose (P < 0.05). (14)
Now this is very interesting. You'll note that the most fat was lost by the group in this study who used the highest dose of Testosterone Enanthate (600mgs/week), and the most Fat Free mass, Strength and Muscle Volume was gained, when compared to any of the lower doses studied (14). Basically, the more Testosterone Enanthate you use (and this holds true for almost all steroids), the more gains you'll get! Of course, that the previous statement will ruffle some feathers in the "less is more" club, but that's simply too bad; more Testosterone Enanthate = more muscle, more strength, more size, and less fat.
Did the men in this study experience side effects at the 600mg dose? Well, HDL cholesterol was lowered (but not total cholesterol or triglyceride levels), and two guys got Acne. Not exactly cause for a Senate Investigation. (14)
Of course, the usual nasty side effects you can get from any form of injectable testosterone are possible with Testosterone Enanthate; gynecomastia, water retention and high blood pressure are all possible, but they are very overstated or controllable in many instances.
A large percentage of those side effects occur from the body's ability to turn Testosterone Enanthate, which is again simply a testosterone hormone into estrogen via a metabolic pathway mediated by the aromatase enzyme. This process, known as aromatization causes a portion of testosterone to be converted to estrogen. Aromatase Inhibitors, Anastrozole (Arimidex) andLetrozole (Femara) can combat this very effectively, and are usually necessary with doses over a gram per week, and often recommended with lower performance doses.
Now that we understand Testosterone Enanthate, lets talk about cost. You should be paying no more than $75 for a 10cc bottle of Testosterone Enanthate, dosed at 250mgs/ml. Of course, as usual, prices fluctuate depending on the brand or supplier, but $75 is a standard underground label range. Even so, you can easily obtain Testosterone Enanthate in high quality form from an underground lab for even less, as little as $40 per 10ml, but youll need to do some digging. As for human grade forms, $100+ for 10ml is quite common, especially if its purchased directly from the pharmacy; however, with the right large supplier you can easily find $60 pricing; evenTestoviron Depot, considered one of the best Testosterone Enanthate compounds on earth has been found for as little as $5 to $7 per ampule.

Testosterone Cypionate

Testosterone-Cypionate is one of the most popular forms of testosterone the world over and the most commonly used testosterone in hormone replacement therapy . a very powerful anabolic and androgenic hormone, Testosterone-Cypionate is equal in both regards and is one of the most efficient and effective hormones we can use for almost any purpose.
To understand Testosterone-Cypionate we only need to understand the hormone testosterone and once we do we can understand how the various esters available, in this case Cypionate affect its mode of action.
By its mode of action Testosterone Cypionate increases both nitrogen retention in the muscles as well a protein synthesis; increases red blood cell mass and blocks and reduces muscle wasting hormones such as cortisol. Further, by its ability to increase IGF 1 production in the body, Testosterone Cypionate becomes even more anabolic in effect when administered in a fashion that increases levels to a performance enhancing range.
As a testosterone based hormone attached to the Cypionate ester, Testosterone-Cypionate has a half-life of approximately 12 days. This is a fairly long half-life and is generally the longest half-life of any commonly used single ester form of testosterone. Because it has a long ester attached in the Cypionate form the effects of this steroid will last a very long time; for example, 200mg of Testosterone Cypionate will yield an active 100mg of testosterone even 12 days after the last injection; of course assuming one is administering the hormone more often than every 12 days the total amount will be much higher but vary depending on the total dose.

The Benefits of Testosterone Cypionate
The benefits of Testosterone-Cypionate are truly immense and provide every trait one would be after through the use of anabolic steroids. By its mode of action Testosterone-Cypionate has the ability to increase both strength and size to a large degree which is by-in-large the principle desire of any anabolic steroid user. Further, because increased lean tissue improves our metabolic rate and because Testosterone-Cypionate affects muscle wasting hormones in a positive manner body-fat is often reduced when the steroid is used.
You need to understand, using Testosterone-Cypionate will not automatically lead you to gaining massive amounts of muscle tissue on its own; if a large muscular physique is what you are after you have to feed it but by doing so in conjunction with testosterone therapy we increase the efficiency of the food we are eating which can lead to a more muscular physique. Further, in the same light yet in the opposite direction, those who are after a leaner physique find Testosterone-Cypionate to be a perfect choice as its mode of action aids in preserving lean muscle mass when on a calorie restricted diet. Plus, when dieting, the more muscle mass we can hold onto the greater our metabolic rate will be, the greater our fat-loss will be and the more
pleasing our physique will be in the end.

The Side-Effects of Testosterone Cypionate
All medications, hormones and non-hormones, steroidal and non-steroidal alike carry with them the possibility of negative side-effects, even Aspirin and Testosterone-Cypionate makes no exception. However, when used by healthy adult men and when used responsibly many of these side effects can largely be avoided and the individual will only enjoy the positive benefits.
The most common side-effects brought on by Testosterone-Cypionate are of an estrogenic nature. Testosterone will convert to estrogen through the aromatase process and can bring about such negative effects such as Gynecomastia, water retention, blood pressure and cholesterol issues to name a few. Further, while we can largely prevent these side-effects from occurring there is one side-effect that is assured; testicular atrophy. When we administer Testosterone-Cypionate we are taking in a synthetic testosterone and by doing so our body no longer requires its own natural production. Since testosterone is produced in the testicles, once production comes to a halt the testicles shrink; however, once use is discontinued and production begins again they will return to their normal size.
There is a strong risk to reward ratio in play when using Testosterone Cypionate and generally all anabolic steroids; the more you use the greater the benefit but the more you use the greater the risks. While this is a reality, regardless of the amounts you use there are things we can do to avoid nasty side-effects brought on by the aromatase process. The use of an aromatase inhibitor (AI) will greatly reduce your chances of Gynecomastia and will greatly aid in unwanted water retention; further, as controlling estrogen in this manner will aid in keeping cholesterol and blood pressure stable it really doesn’t make any sense not to use an AI. However, even with an AI water retention will occur in those who eat more carbohydrates than they need; this is mentioned simply because many blame testosterone on their water retention when bulking when the truth is they are simply overeating. Further, through sound dieting principles, even when bulking, supplementing with fatty acids can largely control your cholesterol and is strongly advised if testosterone is going to be used.

Testosterone Cypionate Cycles & Doses
Testosterone-Cypionate is truly a perfect steroid for any purpose; be it hormone replacement therapy (HRT), performance enhancing, bulking or cutting purposes it is a fine choice in all events. While 200mg every 7-10 days is common among HRT patients the dosing among performance enhancers will vary. 400mg-500mg per week split into two even doses is generally the rule of thumb for any beginner and quite commonly the max many will ever use or need. While we can safely use 1,000mg per week the risks will increase but such dosing is common in bodybuilding and power lifting circles and even beyond. An interesting note, while injections of 1-2 times per week is all that is needed, in recent years many competitive bodybuilders have begun injecting long ester based testosterones every other day, including Testosterone-Cypionate. The idea is to keep blood test levels at their peak max and while this would prove to be unnecessary on paper many bodybuilders report a more stable feeling by following this protocol; remember, what’s on paper does not always match up with real life.
As for your Testosterone-Cypionate cycle, most will find 8 weeks of use to be the bear minimum with 16 weeks being far more efficient. Regardless of your duration of use a solid post cycle therapy (PCT) plan must be in place. Because Testosterone-Cypionate is a long ester based testosterone you will necessarily begin PCT 3 weeks after your final injection, which may include hCG, Nolva and/or Clomid. Those who use hCG are advised to begin use approximately ten days before Nolva/Comid for approximately ten days of use.
