Testenon is a testosterone blend of testosterone enanthate and testosterone propinoate.

Testosterone enanthate is an oil based injectable steroid, designed to release testosterone slowly from the injection site (depot). Once administered, serum concentrations of this hormone will rise for several days, and remain markedly elevated for approximately two weeks. It may actually take three weeks for the action of this drug to fully diminish. For medical purposes this is the most widely prescribed testosterone, used regularly to treat cases of hypogonadism and other disorders related to androgen deficiency. Since patients generally do not selfadminister such injections, a long acting steroid like this is a very welcome item. Therapy is clearly more comfortable in comparison to an ester like propionate, which requires a much more frequent dosage schedule. This product has also been researched as a possible male birth control options. Regular injections will efficiently lower sperm production, a state that will be reversible when the drug is removed. With the current stigma surrounding steroids however, it is unlikely that such an idea would actually become an adopted practice. Testosterone is a powerful hormone with notably prominent side effects. Much of which stem from the fact that testosterone exhibits a high tendency to convert into estrogen. Related side effects may therefore become a problem during a cycle. For starters, water retention can become quite noticeable. This can produce a clear loss of muscle definition, as subcutaneous fluids begin to build. The storage of excess body fat may further reduce the visibility of muscle features, another common problem with aromatizing steroids. The excess estrogen level during/after your cycle also has the potential to lead up to gynecomastia. Adding an ancillary drug like NolvadexВ® and/or ProvironВ® is therefore advisable to those with a known sensitivity to this side effect. The antiaromatase ArimidexВ®, Femara, or Aromasin are a much better choices though. It is believed that the use of an anti-estrogen can slightly lower the anabolic effect of most androgen cycles (estrogen and water weight are often thought to facilitate strength and muscle gain), so one might want to see if such drugs are actually necessary before committing to use. A little puffiness under the nipple is a sign that gynecomastia is developing. If this is left to further develop into pronounced swelling, soreness and the growth of small lumps under the nipples, some form of action should be taken immediately to treat it (obviously quitting the drug or adding ancillaries like Nolvadex). Being a testosterone product, all the standard androgenic side effects are also to be expected. Oily skin, acne, aggressiveness, facial/body hair growth and male pattern baldness are all possible. Older or more sensitive individuals might therefore choose to avoid testosterone products, and look toward milder anabolics like DecaDurabolinВ® or EquipoiseВ® which produce fewer side effects. Others may opt to add the drug ProscarВ®/PropeciaВ®, which will minimize the conversion of testosterone into DHT (dihydrotestosterone). With blood levels of this metabolite notably reduced, the impact of related side effects should also be reduced. With strong bulking drugs however, the user will generally expect to incur strong side effects and will often just tolerate them. Most athletes really do not find the testosterones all that uncomfortable (especially in the face of the end result), as can be seen with the great popularity of such compounds. Although this particular ester is active for a much longer duration, most athletes prefer to inject it on a weekly basis in order to keep blood levels more uniform. The usual dosage would be in the range of 250mg-750mg. This level is quite sufficient, and should provide the user a rapid gain of strength and body weight. Above this level estrogenic side effects will no doubt become much more pronounced, outweighing any new muscle that is possibly gained. Those looking for greater bulk would be better served by adding an oral like Anadrol 50В® or Dianabol, combinations which prove to be nothing less than dramatic. If the athlete wishes to use a testosterone yet retain a level of quality and definition to the physique, an injectable anabolic like DecaDurabolinВ® or EquipoiseВ® may prove to be a better choice. Here we can use a lower dosage of enanthate, so as to gain an acceptable amount of muscle but keep the buildup of estrogen to a minimum. Of course the excess estrogen that is associated with testosterone makes it a bulking only drug, producing too much water (and fat) retention for use near contest time. With the proper administration of ancillary drugs, much of the new muscle mass can be retained for a long time after the steroid cycle has been stopped. Those who rely solely on a fancy tapering-off schedule to accomplish this are likely to be disappointed. Although a common practice, this is really not an effective way to restore the hormonal balance.
