Testosterone phenylacetate (TPA; brand names Perandren, Androject) is an androgen and anabolic steroid and a testosterone ester.[1][2][3] Analogously to estradiol benzoate having been one of the first estrogen esters to be introduced, testosterone phenylacetate was one of the first testosterone esters to be introduced.[4] However, since its introduction, it has largely been replaced by other esters, such as testosterone propionate.[4]

Testosterone phenylacetate was a 50 mg/mL microcrystalline aqueous suspension under the brand name Perandren.[5][6][7][8][9] It was used at a dosage of 50 to 200 mg by intramuscular injection once every 2 to 5 weeks.[6][10] The medication was used to treat hypogonadism and eunuchoidism in males and for palliation of breast cancer in females.[8][9] It was developed by Ciba Pharmaceutical Company.[8]

A study found that, measured by 17-ketosteroid excretion, 300 mg testosterone propionate in oil solution had a duration of 5 days, 300 mg testosterone propionate in aqueous suspension had a duration of 13 days, 353 mg testosterone cypionate in oil solution had a duration of 24 days, and 354 mg testosterone phenylacetate in aqueous suspension had a duration of 66 days.[11][9] In 1955, testosterone phenylacetate in aqueous suspension was said to have the longest duration of any clinically used androgen marketed up to that point.[12]

Testosterone phenylacetate in aqueous suspension by intramuscular injection, similarly to other aqueous suspension formulations, causes local injection site reactions, including local pain, swelling, and tenderness.[11] These symptoms last for several days after the injection and then subside.[11] These reactions do not typically occur with oil solutions.[11] The injection site reactions were viewed as less important in the case of testosterone phenylacetate due to its prolonged duration and less frequent administration.[11]
