I hate the way yohimbe makes me feel. Extenze works alright tho, just don't like getting jitters, why not just take a product you don't need help with in that area? I took h-drol when younger and some natural products today give me just as good of results but none of the sides, plus no shutdown so u maintain what u gain. I'd try optimum alpha, I recently ran it for 8 weeks and put on 14lbs. Starting I was 6'1' 230lbs at 10% bf, finished 244lbs at 9% bf. amazing results, but I was try hard, lifting hard 6 days a week and 7-8 meals a day.
