Good thread. I have done IGFLR3 many moons ago, and I do think it helped my shoulder tendons survive, at least temporarily, the torture to which I was then subjecting them. I have not used it in years, principally because I think genuine IGFLR3 is hard to come by, and HGH and other compounds are equally if not more effective for me in helping my tendon issues. That said, I am attracted analytically to the concept of IGFLR3 as triggering the development of satellite cells rather than the enlargement of existing cells. I may try it again in the future given my chronically bad shoulders!
