I see more and more people adding igf to an AAS cycle with apparently good results, and I'm considering it for my current cycle too. The igf benefits drop off after about 4 weeks, and this is thought to be due to negative feedback causing HGH production to stop. But if this is the case wouldn't the gains from AAS be affected due to the lack of HGH once you stop igf? What's everyone's experience with igf and AAS?
