Ive been injecting igf-1, 2 days on and 2 off at 10mcg's 3-5x/day and on the other 2 days I been doing 2iu's of hgh 4x/day and am having great results compared to when I did igf-1 @ 60-100mcg's/day in a single shot. Lots of shots but hey..... its easy with an insulin syringe. And worth the results I'm seeing so far. Just mix 1cc of AA with the 1mg of igf in the vial and each tick on the syringe is 10mcg's. I suck the BS water in my syringe first and then one tick of the igf. That easy
