Yep thats the good stuff, the good thing about injecting IGF is that you dont have to have your liver convert it. When your body releses HGH or you inject HGH, your liver has to convert it to IGF-1, that is were all the growth takes place in your body. But some peoples liver do not convert it taht well and a lot of it is wasted. By taking IGF directly you bypass the liver, cut out the stain on it as well, get the full benifit, and cut out tons os side effects.
Also the IGF that your body makes only alsts in your system between 20min-60min, the IGF-1LR3 that you take through injections lasts 16 hours in your body, the benifits are unreal as you can see from what I have posted.
