I got this from someone who copied it from Meso.They said it was part of a post made by someone claiming to work in the medical field.....................Here's a little fact that many don't know, IGF has an affinity for non-specific absorption to glass or other surfaces, with out the addition of a carrier protein like bovine serum albumin. So in simple terms your IGF sitting in your glass vial is being absorb into the glass surface.Am I telling you to add bovine serum albumin to your IGF; ABSOLUTELY NOT injecting this would cause an immune response by your body. Why do you need to know this, well in a few weeks when your not feeling the effects of the IGF anymore , there's one of the reasons why. Have I used IGF, yes. Do I feel it works, yes.But to use it without doing your research, is foolish, remember this is a growth factor and as such cause the growth of both good and bad cells. Will it cause localized growth , no way no how and saying so shows a lack of understanding of the functioning and processing of peptides in the human body.
