Methenolone enanthate is an injectable steroid derivative of dihydrotestosterone (DHT) with a mild myotrophic activity index 0.85 and a low androgenic index 0.12. It's half-life dose dependent and is generally about 5 days. Methenolone is considered one of the safer steroids, meaning it has few side effects.

Methenolone, because of it's low androgenic activity does not suppress endogenous testosterone secretion. Methenolone also is not overly suppressive of the hypothalamic-pituitary axis (HPTA), but will become suppressive with increased doses.
