Testosterone is a form of the male hormone testosterone. Testosterone Decanoate is commonly used in the mixture of sustanon. After an application the decanoate ester releases a long lasting effect of testosterone into the bloodstream. This lasts approximately 3 weeks similar to nandrolone decanoate but more than enanthate and cypionate depending on the users metabolism and initial hormone level. To maintain the physiological levels of the testosterone in the body it is necessary to receive applications every 3 weeks to maintain hormone levels
Testosterone Decanoate is a modified form of the male hormone testosterone. It is an ester of a carboxylic acid-decanoic acid bound to the 17-beta hydroxyl group. These modified forms of testosterone are not as polarized as the free testosterone which generates slow absorption from the injection site. Once the testosterone decanoate is in the bloodstream, the decanoate ester bond is separated from the testosterone making it free and active. This type of esterified steroid is designed to prolong the effect of the testosterone in the body, requiring less applications compared to other steroids that are not esterified. Testosterone decanoate has a half life of approximately 3 weeks.
All types of testosterone have the ability to aromatize in the body due to the action of an enzyme called aromatase, this is also responsible for the conversion of testosterone to estrogen. Due to the prolonged effect of testosterone, hormone levels tend to fluctuate after every application increasing the risk for higher estrogen levels in the blood system. It is essential to use antiestrogens to control estrogen levels and to decrease the risk of gynecomastia, water retention and body fat gain. These type of products have no hepatotoxic effects in comparison to other oral substances. Like all androgenic anabolic steroids, testosterone has the ability to reduce the production of endogenous testosterone.Prolonged use could cause hypogonadism which could cause an excessive loss of muscle mass and an imbalance in anabolic and catabolic hormones at the termination of testosterone treatment. It is important to complete a proper post cycle therapy to stimulate the production of endogenous testosterone to avoid losing significant muscle mass in a short period of time.
Testosterone is a fine white powder, easy to compress, stable in normal environmental conditions and has a low melting point in comparison to other substances.
Testosterone Decanoate is an oil base that is generally a very light yellow to transparent in colour. In high concentrations testosterone decanoate does not crystallize within the vial. The viscosity in comparison to other substances is higher and it is uncommon to be found on it own.
