I have used both and there is a LOT of difference in NOT only purity but also stability. If people understand IGF just a bit (as most people do), they know that IGF is even less stable then GH; thus, when you buy media grade IGF what happens is that it's ALREADY reconstituted and during shipping so much LESS stable then receptor grade products which come as lyophilized powder (white dry powder). Let me put it this way, I've put BC water in TOO fast into IGF (instaed of dropping it in, I squirted) and my IGF bubbled up and was useless - basically ruinted, that's how FRAGILE it is. Yes, it was an expensive lesson but it made me realize how fragile these products are. Thus, I only suggest lyophilized powder (white dry powder) receptor grade products which are high-quality, more stable, and you will KNOW what you're getting. Don't have some company reconstitute it for you, god knows how they did it, do it yourself and see the product yourself.
