Testosterone (T.) derivatives for clinical use. T. esters for im. depot injection are T. propionate and T. heptanoate (or enanthate). These are given in oily solution by deep intramuscular injection. Upon diffusion of the ester from the depot, esterases quickly split off the acyl residue, to yield free T. With increasing lipophilicity, esters will tend to remain in the depot, and the duration of action therefore lengthens. A T. ester for oral use is the undecanoate. Owing to the fatty acid nature of undecanoic acid, this ester is absorbed into the lymph, enabling it to bypass the liver and enter, via the thoracic duct, the general circulation. 17-0 Methyltestosterone is effective by the oral route due to its increased metabolic stability, but because of the hepatotoxicity of Cl 7-alkylated androgens (cholestasis, tumors) its use should be avoided. Orally active mesterolone is 1 a-methyl-dihydrotestosterone. Trans-dermal delivery systems for T. are also available. 

Also referred to as heptanoic acid enanthic acid enanthylic acid heptylic acid heptoic acid Oenanthylic acid Oenanthic acid. Enanthate is one of the most prominent esters used in steroid manufacture (most commonly seen with testosterone but is also used in other compounds like Primobolan Depot). Enanthate will release a steady (yet fluctuating as all esters are) level of hormone for approximately 10-14 days. Although in medicine enanthate compounds are often injected on a bi-weekly or monthly basis, athletes will inject at least weekly to help maintain a uniform blood level...
