What grade of compunds do UG labs use?

[katton]

Are there different grades of test? Like one with higher bioavailabilty than the other or is all test equal in quailty be it UG or Human grade.

UG is UG, there can be anything in there. Read about different labs, and youll get different info. RT is a really good one, theres some others, but just search around. The only thing that changes test is the ester(correct me if Im wrong). Prop or suspension will have more active test per gram than enanthate or cypionate because of the weight of the ester. As for the grade, human grade gear has the same ingredient as the vet gear, but human grade is way more sterile.
