Your goal
Healing your gut
Here's the honest truth: no peptide is actually proven to fix your gut in humans yet. The ones people talk about for gut repair and inflammation look promising, but the good results so far come almost entirely from animal studies. Treat this as an early, hopeful area, not a solved one — there's no 'what works' tier here because nothing has earned it.
Promising, still unproven
3Interesting early signals — not proven yet.
BPC-157
EmergingIt's the go-to gut-repair peptide and protects the gut lining from ulcers and NSAID damage in study after study — but nearly all of that proof is still in animals, not people.
KPV
EarlyA tiny peptide that calms gut inflammation and eases colitis in animal models by shutting off the body's main inflammation switch, with no human trials yet.
VIP
EarlyA natural gut hormone that may protect the lining and calm intestinal inflammation, but it's a research subject, not a proven self-use treatment.
Mostly hype — be skeptical
4Lots of buzz, little human proof. Tread carefully.
LL-37
EarlySometimes hyped for gut healing, but research shows it can actually damage the gut lining, so be very cautious.
Liraglutide
EarlyA real, proven drug for diabetes and weight loss that acts on a gut hormone and slows digestion, but it's not a gut-health treatment and commonly causes nausea and diarrhea.
GHK-Cu
EarlyCalms inflammation in many tissues in lab studies, but there's no real gut-specific evidence behind the claims.
Epithalon
EarlyAn anti-aging peptide with no meaningful human data and nothing specific to show for gut health.
The honest bottom line
If you remember one thing: the gut peptides everyone raves about (BPC-157 and KPV) are promising in animals but unproven in humans, so go in with realistic expectations and a good doctor.
