Had a buddy of mine give me about 100 (10mg) pills of Oxavar. Bottle says it's made by bio tech. I can attach a pic if needed. Can anyone tell me anything about this stuff? He said he was taking about 20-40mg a day and didn't notice much difference. I think he didn't do enough mg/day, since he weighs about 275. I'm just curious if its worth taking, and if so, how many mg/day? Thanks!
