It´s a great choice for this purpose, and many competitors have used it very successfully to retain muscle while on a calorie reduced diet. The reason Primo is so useful for this purpose is that one of its primary functions is to help your body retain nitrogen at a greatly enhanced rate. The greater your nitrogen retention is, the more muscle you will build. In the case of using primo as a pre-contest drug, this nitrogen retention will help you retain muscle and ensure that your dieting preferentially favors fat loss over muscle loss. The half-life is about 5 days. The drug is particularly excellent for use as the last injectable used in a cycle, since for any given anabolic effect it gives much less inhibition than other steroids such as testosterone, nandrolone, or trenbolone. Therefore, residual levels of Primobolan can allow recovery in the taper while still offering useful anti-catabolic or even anabolic support. Michael Mooney and many other respected doctors who work with AIDS patients have found sufficient evidence to claim that Primobolan is an immune enhancer and as such is very useful for AIDS patients. Effective dose(oral): (Men)50-100mgs/day; (Women) 10-25mgs/day Effective dose (injectable): (Men) 350-600mgs/week; (Women) 100mgs/week Active Life: 10-14 days (injectable); 4-6hrs (oral) Detection Time: 4-5 weeks Anabolic/Androgenic Ratio (Range): 88:44-5 Store in temperature not exceeding 77oF(25oC), in a dark place.
All anabolic/androgenic steroids when taken in doses sufficient to promote muscle gain are expected to suppress endogenous testosterone production. Without the intervention of testosterone-stimulating substances, testosterone levels should return to normal within 1-4 months of drug secession. Note that prolonged hypogonadotrophic hypogonadism can develop secondary to steroid abuse, necessitating medical intervention. Primobolan® is generally described as having a low impact on endogenous testosterone production. While this may be true in small clinical doses (20-25 mg daily), this may not be a major distinction when used for physique- or performance-enhancing purposes. In one study, more than half of the patients receiving only 30-45 mg per day noticed a 15-65% suppression of gonadotropin levels. 585 While this is far from having no hormonal impact, the suppression caused by methenolone acetate may still be less pronounced than with many other agents. If Primobolan® is used at moderate doses for less than 8 weeks, hormonal recovery should not be a protracted experience.
