Tiger88 Let's say you lost 60 lbs in four months, prep h or thimo is not going to do alot. But if you have dropped 15 lbs in 6 weeks for a show they will help thighten a little bit of loose skin and both draw water from the subcutanous area. So yes they help to get the water out of the low back, but only a little, but sometimes that is all you need.
jubei europa sports has it, I've seen it advertised all over the place though. [/B]
