MBL PRIMO 100 is an injectable steroid derivative of dihydrotestosterone (DHT) with a mild myotrophic activity index 0.85 and a low androgenic index 0.12. Its half-life is dose dependent and is generally between 5 and 10 days. Methenolone is considered one of the safer steroids, meaning it has few side effects.
Methenolone, because of its 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. Primobolan is the number 1 choice for female athletes and bodybuilders next to Anavar since it offers them an excellent anabolic profile without the worry of virilization.
Metenolone enanthate was introduced for medical use in 1962.[6] In addition to its medical use, metenolone enanthate is used to improve physique and performance.[6] The drug is a controlled substance in many countries and so non-medical use is generally illicit.[6] It remains marketed for medical use only in a few countries
