I've used many diffirent types of gear, and the ones I trust the most? Well its kind of a toss up between, Organon, Scherring, QV, and IP. If a sterile product is an concern, You can't go wrong with Organon, QV, and Scherring. But for Mg. to Ml. ratio's IP Is the right choice. I'm not saying that IP is not sterile, it is somewhat a very clean product, but I have heard complaints from time to time. As for orals there is several companys I would recomend. Organon, British Dispensary, British Dragon, Scherring, Anfarm, and of course IP. I've had great results with alot of British Dispensary and IP tabs. For dbols nothing beats British Despensary's Thai's. Its the best choice for stacking on a bulk cycle with sustanon or test enanthate.
