Which peptides are actually approved drugs? Trying to separate signal from hype

So much of the online conversation blends approved peptide medications with experimental research compounds as if they're the same tier of evidence. I'd like to build a clearer mental map of which peptides have actually cleared regulatory approval for a medical indication.

Off the top of my head: insulin obviously, the GLP-1 class (semaglutide, tirzepatide, etc.), and things like octreotide. I know there are more. Not looking for anything about using these, just trying to understand the landscape of what's genuinely been through approval vs what lives in the research-only bucket.

Good framing, and your starting list is solid. There's a real ecosystem of approved peptide drugs: insulin and its analogs, the GLP-1 receptor agonists you named, somatostatin analogs like octreotide, desmopressin (a vasopressin analog), leuprolide and other GnRH analogs, calcitonin, and more across oncology and metabolic medicine. These have defined indications, trial data, and regulatory review behind them.

That's categorically different from the long tail of compounds that show up in forums with mostly preclinical or anecdotal support. The single most useful habit is exactly what you're doing: asking 'is this an approved drug for a defined indication, or a research compound?' before weighing any claim about it.

Seconding all of that. One caution worth stating plainly for anyone reading: even for an approved drug, approval is for a specific indication, formulation, and population studied. A peptide being 'approved' doesn't mean every use you read about is supported, and it doesn't transfer safety to a chemically-similar research analog. Keep the evidence attached to the specific product and use, and route any personal decision through a clinician who knows your history.
