When used in conjunction with other steroids Primobolan can bring out the best in all cutting cycles and athletic improvements. Many bodybuilders regularly use it with Anavar, Trenbolone and winstrol to improve cutting power and overall strength. For females in short and concise cycles Primobolan can be extremely beneficial on its own. Many even report that they see massive improvements in athletic power and in bulking when taking moderate doses. Primobolan works better on its own in women but can help men achieve explosive results when they are using other types of steroids.
Schering did used to make a fast-acting primo, that is, the Methenolone Acetate version as an injectable. However this was 20mg/ml and is no longer made. Some underground labs, particularly in the US have recently been making injectable methenolone acetate. However beware, as there is a reason that it was originally made at 20mg/ml; anything from 50mg/ml and above of this product will cause severe injection site pain following injection, and furthermore pretty much everyone I have read of who has tried this form of Primo at such concentrations will get flu like symptoms after every shot for a day or so. Thus the reason why methenolone acetate is not marketed by any major underground labs.
