Testosterone Decanoate CAS 5721-91-5
Testosterone decanoate bodybuilding, a.k.a. Neotest 250, is probably best known as one of the ingredients in Sustanon. Neotest 250 is testosterone with the decanoate ester, a slow-acting long ester, similar to testosterone enanthate.
Testosterone decanoate commonly used in intramuscular injection solution, the oil absorption is slow, function is strong and durable, can maintain time for just a few days. More specifically, Neotests decanoate ester releases for approximately three weeks after the injection, making it similar to but slightly slower than both the cypionate and enanthate esters. At present, the decanoate version of testosterone can only be found within sustanon 250.
Testosterone Decanoate is the most commonly associated brand name to the Testosterone Decanoate product. This is an injectable testosterone hormone attached to the large / long Decanoate ester. The ester itself does not affect the compounds functions and traits; no ester has this ability. However, the attached Decanoate ester does affect the testosterone hormone's release time. This will be a very slow acting testosterone, and it will provide a slow, steady release of the hormone after a single injection.
Testosterone Decanoate As with all forms of testosterone, this product will cause weight and strength gain, fat loss, a libido increase, an increase in IGF-1 levels, Red Blood Cell count, and of course increased recovery from training.
Again, as with all forms of testosterone it is subject to aromatization as well as 5alpha-reduction, which are the pathways through which testosterone is converted to estrogen and dihydrotestosterone respectively. Excess build up of estrogen can be responsible for gynocomastia (development of female breast tissue in males) as well as bloating and water retention. Dihydrotestosterone can cause both acne as well as hair loss.
As with all forms of exogenous hormones, using this product will shut down your body's natural production of testosterone. In addition, cholesterol, immune function, and several other health markers may be adversely affected.
