I was on the fence with that (Reforvit-B) and Bionabol. Unfortunately, I chose the latter. Anyway, everyone who has used Reforvit-B has been happy with the results. Personally, with d-bol, I would only go with British Dispensary Pink Thais. Naps (Romanian) are supposedly good, too. Bionabol, from personal experience, is not worth it.
