Yo Rocco,
Hey I have been using MC IGF for the past three years straight and I am up to 200 mcg pre workout, no issues at all, never hypo and see my doc every two months for check up and blood work....all good.....
I highly recommend MC IGF you wont be sorry, the best supplement you can use out there.....apply it to the muscle you're working that day and see / feel instantly a noticeable difference..
Peace E
