I've used igf1-lfr1 before but never really researched much about it, was just spur of the moment purchase. It's a fantastic product though, really like it. I was thinking about it but since cjc-dac increased baseline values up to 300%, i figured it wasn't really needed on top of everything else.
With that said, pretty sure you need to inject it twice per day, everyday if im not mistaken to be optimal.
Or maybe I just did that because you're supposed to do that with GH anyhow...
