A woman may get away with one short cycle of winny, var, or primo but I think using any form of test is pushing it. However, I do think some of it depends upon the woman too. However, I have seen some women who can use one product at a safe dosage and it wreck them while another woman can do the same thing and have only positive things happen for them without the bad sides. Actually, I had a girl who ended up giving me a couple months supply of Nandro-phenyl and primo because after a short time it started messing with her in a bad kind of manly way.
