Keep in mind that UGL isotretinoin is going to degrade fairly fast. It would be a good idea to stick with pharma or maybe gradually use a higher dose to compensate if you go with UGL.
As for recommendations, I live in Canada, so I can't speak much about sourcing, but BGpharma has pharmagrade Accutane and the gel as well. I've used his stuff, and it's great; however, I will say that he's lost some respect from me over the years. He used to provide excellent customer service, but now it seems that he no longer replies to emails and would prefer to reply to posts on Meso...
