I've recently been taking IGF1-LR3 that I purchased through a friend who I trust. It came in 4 vials with powder in it and the way I was told to take it worked out to be 100mcg pre workout. I have been taking a little over half what I was told as this was my understanding through my own research. Let me tell you.. 50-60mcg of this stuff is ridiculous. I have never sweat so much while working out on this stuff than from taking anything else. More than tren which I've used 100mg eod for 6 weeks and more than clen which I've pyramided up to 140-160mcg. Has anyone else experienced this ridiculous sweating and hunger pains with lr3? I'm 6ft just under 200lbs and about 8% body fat.
