To strengthen the anabolic properties of testosterone, more than 100 synthetic steroid derivatives have been described for human purposes. The anabolic effect promotes protein synthesis, muscle growth and erythropoiesis. In clinical practice, substances with anabolic effect are needed to overcome various catabolic states. However, none of these compounds are devoid of androgenicity. Androgenic and anabolic properties of anabolic steroids cannot be totally separated. Therefore, it is more appropriate to use the term anabolic androgenic steroids (AAS).
Primo is available in both oral and injectable form, but it has not proven to be a successful mass building drug when taken orally because the liver usually destroys any traces of Methenolone Acetate that is ingested through the mouth. Similar to Anavar, it is mild and contains less of those steroid properties which leads to water retention or acne or any other side effects that are related to estrogen. This makes Primo a very successful drug amongst those who become easily prone to side-effects like skin problems and digestive issues.
