20-50mg depending on your experience. closer to 20 if youre new to taking aas, closer to 50mg if youre and experienced and want more gain. I am sensitive to aas and get great gains off low doses, but I guess Im lucky, others need more its an individual thing, plus I dont want to look like a freak. I take 30, but have gone up to 50, but I think that is a waste of money for me. Others may go up to 100, but there is no accounting for intelligence.
