The first anabolic steroid that was effectively produced was testosterone. A fast-acting, short-ester, oil-based testosterone injectable molecule called testosterone propionate is frequently administered to treat male hypogonadism, or low testosterone levels, and its numerous symptoms.The Propionate Ester: An ester is any of a class of organic compounds that react with water to produce alcohols and organic or inorganic acids. Most esters are derived from carboxylic acids, and injectable testosterone is typically administered along with one or multiple esters. The addition of a carbon chain (ester) attached to the testosterone molecule controls how soluble it will be once it’s inside the bloodstream. The larger the carbon chain, the longer the ester, and the less soluble the medication; a large/long ester will have a longer half-life. The inverse is true of short carbon chains, like the propionate ester, which acts rapidly upon the body and evacuates the body at a similar rate. With a three-carbon chain, the testosterone ester possesses the shortest half life of all testosterone esters at 4 days.
