I have never taken IGF1 LR3 and am considering a doing a 12 wk cycle along with the rest of my gear. I have done HGH in the past with great results. If one of the vets that has experience with both could put their opinion in it would be greatly appreciated. I was considering doing 50mcg a day of the IGF1. In the past with the HGH i would run 4-5 IUs a day. I am 6'5 weigh right at 245 and very lean.
