For some background information I've been running MK-677 at 25mg for 2 months, worked out natural for about 3 years and I'm unsatisfied with my progress. Mainly looking for something that can help build muscle. My only concern I have with IGF-1 LR3 is the possibility of accelerated bone maturation thus shortening my remaining window of skeletal growth. I'm 5'10 currently if that's relevant.
