I think we are sort of in the worst of both worlds right now re: medicines/supplements/gray market.
FDA approval is expensive slow process. Doctors train for a long time and then work 40+ years entire careers, some without a ton of continuing education.
But then we have an entire gray market because enough legal and practical loopholes to drive a freight train through, such that people are self medicating with dubious substances of dubious origin of dubious purity sourced via dubious means.
Even if peptides work, you have no idea what side effects they have, or if the ones you are taking are even real, not contaminated/tainted in some manner, etc. Given a lot of the hype comes from social media for otherwise healthy people to take them for lifestyle / augmentation reasons.. to me the risks still outweigh the rewards.
Real solutions like regulatory reforms to find ways to bring down testing costs seem more important than reforms to make it easier to slap anything on the shelf at GNC as a completely untested “supplement”.
