It seems that Panbesy is exclusively sold and prescribed in Singapore at this time. It uses a 30mg dose of Phentermine hydrochloride, and it is talked about on several online forums. But there is no official source concerning it. Users online have reported feeling more energetic than usual, sleep disturbances, dry lips and throat, a reduction in food cravings, a reduction in appetite, and various other things. In other Phentermine forms we’ve seen, a 30mg dose generally means about 24mg in terms of what your body will have access to. It should be combined with diet, exercise, and therapy to change overall behavior, and it is only for short term use. At this time, we have not actually seen any verification that is sold at this time.
