Testosterone enanthate is a type of androgen drug, and it is a synthetic compound of testosterone proprionate and testosterone enantate. Its effects are the same as those of testosterone acetate, which include promoting the development of male sex organs and secondary sex characteristics and resisting estrogen. It also has protein assimilating effects, which allow it to help muscle growth and weight gain. White or yellowish-white, crystalline powder. Delatestryl,Squibb,US,1954 Uses：Testosterone Enanthate is a derivative of testosterone (T155000), the principal hormone of the testes, produced by the interstitial cells. Testosterone enanthate is a heptanoate ester and a sterol ester. It has a role as an androgen. It is functionally related to a testosterone. Manufacturing Process A mixture of testosterone, pyridine and oenanthic acid anhydride is heated for 1 1/2 hours to 125°C. The cooled reaction mixture is decomposed with water while stirring and cooling. After prolonged standing at a temperature below room temperature, the whole is extracted with ether and the ethereal solution is washed consecutively with dilute sulfuric acid, water, 5% sodium hydroxide solution, and again with water. The crude ester remaining on evaporation of the dried ether solution, after recrystallization from pentane, melts at 36° to 37.5°C.
