Ok. I have used Igf before and had great results. The pumps were crazy to the point I was catching cramps and I was tired all the time. I was taking 60mcg to 100mcgs and i felt the pumps immed. Well I have been taking MC IGF since Thursday of last week. I started at 60mcg and yesterday up it to 100mcg. I still dont feel any pumps nor am I tired at any point. Why am I not feeling anything yet?
