smart buy......You will so very happy with your purchase and probably be upset with yourself because you didnt jump on this a lot sooner.....MC IGF to me has worked better than anything I have tried....beats any supplements, GH and AAS....I ran it for 6 months without any gear and didnt lose any muscle and totally gave my physique a different look.....I've been running it 2x for pre-contest coming up in two weeks............
