Compound type: Long-Acting Testosterone Ester — AR Agonist (~5-day half-life) CAS Number: 315-37-7
What is Testosterone Enanthate?
Testosterone Enanthate (TE) is testosterone esterified at C17β with enanthic (heptanoic) acid, providing a ~5-day half-life after intramuscular injection. Like all testosterone esters, TE is hydrolysed by non-specific esterases in blood and tissue to release free testosterone, which then binds AR, drives 5α-reduction to DHT, and aromatises to oestradiol. TE is among the most-studied androgen esters — used as standard TRT formulation in clinical trials and the backbone of HPG axis, anabolic, and androgen comparative research. Distinguished from Testosterone Cypionate (~8-day) by shorter half-life and slightly different oil vehicle properties.

Ester Comparison
5-day vs. Cypionate (8-day) vs. Propionate (2-day) half-life comparative studies
How does Testosterone Enanthate differ from Testosterone Cypionate?
Both are long-acting testosterone esters but with different half-lives: Enanthate ~5 days, Cypionate ~8 days. The longer cypionate ester produces more stable plasma levels. Enanthate is the standard European TRT formulation while Cypionate is predominantly US-prescribed. Both produce identical biological effects via the same testosterone pharmacology.
