It's a drug meant to treat diabetes.
People who can afford meal plans and personal trainers and don't have the same 9-5 struggle as everyone else are using it because they're too lazy to train and eat right.
The amount of the medicine is reducing because these a$$holes are using up the supply, so people who actually need it can't get it. It's not a weight loss drug and when you start taking it you have to take it for life. It also has various side effects that can harm you long term if you don't need to be on it.
and viagara was created for hypertension
but I agree anything natural is better than these quick fixes
