not to sh!t on UG labs, cuz there are plenty of good ones out there, a caution when deciding to use one:
some punk chemistry reject who got hold of some powder can mix this stuff in his bathtub for all you know, you could get a serious infection from bacteria, bogus shit, underdosed, etc... be careful when going UG, make sure its "legit" from a trusted lab, and that it is actually from that lab and not copied, as some scammers and new chemmies do.
