Methenolone Enanthate is the injectable version of methenolone with a long ester attached to slow absorption of a the active methenolone compound and provide steady blood concentrations. The oral version of this compound is practically identical with the difference being the attached ether (the oral version has a shorter acetate ester attached). Both versions of methenolone are good choices for cutting cycles for men and/or women and have shown to maintain muscle while on a low-calorie diet. Methenolone Enanthate provides a less frequent administration mode for methenolone and anecdotally appears to require a lower overall dose in order to be as effective as the oral acetate version.

Methenolone has a reputation as being a very safe steroid and in doses of up to 200 mgs/week very little side effects are reported. Unfortunately, many users also report minor gains at best using such a low dose and more pronounced gains seem to occur at 350 mgs/week (100 mg EOD) and up. While methenolone is mild without much HPTA suppression, higher doses will result in negative feedback in this regard. Also, some users report hair loss while using Primo so a product like finasteride may be necessary while cycling methenolone. On the plus side, because of the few side effects exhibited by primo use, an anti-estrogen is likely not necessary.
