never tried hoodia but i did try phentermine and lost 4 stone really quick. they were from a dodgy doctor in derby. i think they are similar slimming pills though
I'm not surprised you lost weight "really quick" - that's an amphetamine...
From Wiki -
Since the drug was approved in 1959 there have been almost no clinical studies performed. The most recent study was in 1990 which combined phentermine with fenfluramine or dexfenfluramine and became known as Fen-Phen.[citation needed]
In 1997 after 24 cases of heart valve disease in Fen-Phen users, fenfluramine and dexfenfluramine were voluntarily taken off the market at the request of the FDA. Studies later proved that nearly 30% of people taking fenfluramine or dexfenfluramine had abnormal valve findings. The FDA did not ask manufacturers to remove phentermine from the market.
