NONE nothing works like AS, period. Anavar is the least potent...but a great starter.... ....prohormones suck. They are a waste of money. I'm certain others will chime in. Obviously, if you've asked...you've been lurking and reading that Anavar is the most mild.....and you are tying to find a natural equivilent? Forget it.
Anyway's, that's obviously a "natural" question.... I'd try supp's from Primordial and protein factory if you want shit that works. I have 4 bottles of legal-gears methyl- 1d you can HAVE.....just pay for shipping. It's crap.
