I was gifted 10ml of lipostabil.
It made me have to go to the bathroom a lot for a few days. The second time I did it I drank more water (~2.5 gallons/day) and that helped keep my energy levels up.
It's good for the lipid profile. Gave me energy on the first day, but my sleep was very deep, too.
Got a slightly noticeably leaner.
The down side is the price and number of shots you have to take.
Probably best saved for the problem areas. For me that's low abs/low pecs/butt/low back fat.
Wish I had more.
