Primary Use: Primo is not a steroid one would use when attempting to pack on the pounds. Rather, it is used for improving the quality of one’s musculature, which it accomplishes by increasing both muscle hardness and reducing subcutaneous water retention. Primo also stacks well with most aromatizable drugs, as its mild anti-estrogenic component helps in mitigating estrogenic side effects. It is properly regarded as being one of the safer steroids of the bunch, having a lesser impact on cardiovascular function, the liver, kidneys, prostate, etc. Possessing SARM-like traits, Primo is a weak androgen and completely absent of all estrogenic activity. This makes it an ideal choice for those desiring a relatively pure muscle-building effect, with cosmetic side effects rarely manifesting at normal dosages. The number of potential applications for which Primo is well-suited are numerous, as it can be safely and effectively stacked with just about anything.
