I'm not sure about the mc igf-1 from what I hear it is vear hard to get real igf but I see everyone's posts on here about how good it is so I want to try it but because I have type 1 diabetes I have to look in to everything and then look some more and look again cause I can end up in a coma again or I could die again I'm on my 5Th life so I want to know as much as i can so if u can help me it might just help me or it might save someons life
