IGF-LR3 Grades?

**CheddaNips** · 05-08-2008, 02:40 PM

My sources for IGF-LR3 all have 2 different grades of it. Media grade which is a good bit cheeper, and then Receptor Grade which is more. Is there really that big of a difference between the 2 to make a difference?

not too long ago i read the difference is a mere 1-5% difference in purity & that its nearly insignifcant for our purposes

also that true receptor grade would cost a nearly ridiculous amount to obtain, and any "receptor grade" sold by sources is not really that

this topic has been tossed around several times....if i cared to use igf again, i'de search
