Well yeah, the only value amps has for weight loss is via the appetite suppressing effects, there is no other value it ads for this purpose. And suppressing your appetite can be done far easier and safer then using amps for this, that would be way overkill for this single reason alone. Therefore simple coffee or another legal herbal stim like Yohimbe maybe, or any SNS stimulant would be perfect for this. Not saying it would be as pleasant as using amps for weight loss specifically, but definitely just as effective.
