SIUG is an underground lab, so its generic chinese GH that they have labeled. SIUG is a very reputable UG. The chinese generics are a bit better than Jins, either Kefei blue tops (usually 10iu, but there are 4iu also) or brown top (always 8iu). You shouldn't be paying more than $2/iu though for U.S. domestic chinese generic. Since these are labeled by SIUG, and since you are not getting them directly from SIUG, I can say w/ near absolute certainty that you would paying too much. I can also say w/ near absolute certainty that you should not have any concerns about the quality of the product.
