I have been using Organon Sust the past few years. This year, I am using a UGL Test E and there is no difference at all. It's the same thing. The problem with UGL's is they are not always dosed properly and they can have problems being steril, so a lot of people get sick the first couple of weeks on them.
If the dose is correct, there is no difference. When people say pharm grade is far superior to UGL, it is all bullcrap, and those people really have no idea what they are talking about. They are just parrots that go by what they heard from someone who got crappy UGL gear. If there is a difference between the gains you get, then it really is not noticeable at all.
