Fuck!!! Just found this from another site.........
Fast-acting Primo?
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 However beware, as there is a reason that it was originally made at 20mg/ml; anything from 50mg/ml and above of this product will cause severe injection site pain following injection, and furthermore pretty much everyone I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.
