Methenolone enanthate 303-42-4 CAS NO.303-42-4

metenolone enanthate (or methenolone enanthate) is adihydrotestosterone (dht) based anabolic steroid. it is an esterderivative of methenolone sold commonly under the brand namesprimobolan (tablet form) or primobolan depot (injectable). when it interacts with the aromatase enzyme it does not form anyestrogens. it is used by people who are very susceptible toestrogenic side effects, having lower estrogenic properties thannandrolone. methenolone, in form of enanthate and acetate, is available as an injection or as an oral respectively. the injection is naturally regarded as having a higherbioavailability. it is an enanthate ester which is quite long-acting. because it by-passes hepatic breakdown on the first pass, it also has a higher survival rate. the tablets are in a short-lived acetate form. methenolone is not 17-alpha-alkylated, but 1-methylated for oral bioavailability. this reduces the stress on the liver, but also the availability. it is considered one of thesafer steroids, meaning it has few side effects. methenolone has no estrogenic side effects, and its effects on cholesterol levels are minimal. in doses of 200 mg per week or less (intramuscular)blood pressure is rarely altered. it is possibly one of the saferanabolic steroids for females due to very low virilization effects in short-term usage. methenolone is also not overly suppressive of the hypothalamic-pituitary-gonadal axis, although how suppressive is debatable. for this reason, many bodybuilders use it in betweensteroid cycles during their "off-time" to help maintain their gains and strength. the long term safety of such a practice is possibly dangerous and can lead to permanent suppression of thehpta.
