Out of that list...which do u think is the most potent and sterile?
You see here's the thing...it is almost impossible to know. Sure, you could have your product tested, run lab test to check dosage and bacteria levels, if you had the means but even then you're not out of the water. Let's say you test your test-e from a UG source and it comes out dosed correctly and clean for the most part...I say "for the most part" because it wasn't made in a controlled environment...OK, great, but now you'll have to test each batch from each batch number, again, because it's not made in a controlled environment.
Here's the next thing, some UG's start out OK, they at times though get sloppy, especially once they get bigger. Further, the odds that they're using top-shelf powders to make their products are about a million to one...not good odds.
In my opinion, in this day in age it makes no sense to use UG gear. The quality is unknown, always will be, the risk is far greater in terms of health and legal. HG gear is readily available both with a prescription or without if you so choose.
UGL gear makes no sense...zero...none at all.
