Human Long R IGF-1

I found a site that sells Human Long R IGF-1, but there are two different versions available. There is one that is anti-human, and one for human. Is it possible to use the anti-human one since it is way cheaper than the human one? Also whats the recommended dosage of Human long r IGF-1? Also for the human version there is the media grade and the receptor grade, what are the differences?

That's Gropep's site. The anti-human isn't IGF-1, it's antibody specific for IGF-1 LR3. Don't waste your money on the receptor grade. I'm not even sure they'll let you buy from them....give it a go.
