Sorted into six categories by what they actually do. Tap any entry for the full breakdown — what it is, how it works, how long it lasts, how it's given, and what it's used for.
The peptides you can get through a doctor or pharmacy. The ones with FDA approval, prescription pathways, or established clinical use. Where most people begin.
Everything on this site is for learning, not for treating yourself. Nothing here is a recommendation to use, buy, or inject any of these peptides. Real health decisions belong with a doctor who knows your full picture.
Most peptides aren't regulated like vitamins or supplements. Many are prescription-only drugs. Some are still being tested. Some are sold only for lab research. Treating them like a casual wellness purchase is a mistake.
Compounds sold "for research only" don't follow the same manufacturing standards as actual medications. Two vials with the same label can have very different actual contents. Quality, purity, and what's actually in there varies a lot between sources.
For a lot of these peptides, we don't yet know what years or decades of regular use does to a person. Animal studies and a few months of human trials can't tell us about long-term safety.
If something on this site interests you, the next step is a conversation with a doctor — ideally one who knows hormones, metabolic medicine, or the specific peptide you're curious about. Not a forum, not an influencer, not a guy at the gym.
