Relevant peptides organized by clinical indication, with evidence ratings.
Anti-Aging & Longevity
Anti-aging peptide research spans from highly speculative Russian bioregulators to emerging mitochondrial medicine (SS-31, MOTS-c, Humanin) with genuine Phase II data. Differentiating marketing from evidence is critical in this space, which is flooded with unsubstantiated claims.

Cardiovascular Health
Cardiovascular peptide applications span from FDA-approved agents (semaglutide for MACE reduction, oxytocin for obstetric use) to mitochondrial cardioprotection (SS-31) and emerging RAS-targeting peptides (Angiotensin 1-7). The GLP-1 class has the strongest cardiovascular evidence.

Cognitive Enhancement & Neuroprotection
Peptide-based cognitive enhancement ranges from FDA-approved treatments for neurological disease (ziconotide for pain, tesamorelin for cognitive effects in HIV) to preliminary nootropics with human trial data (Semax, Selank) to highly speculative compounds with only animal data (Dihexa, P21). Evidence quality varies enormously across this category.

Immune Modulation & Infection
Immune-modulating peptides range from the well-validated (Thymosin Alpha-1 approved in 35 countries) to the preliminary (Thymalin, Vilon). Antimicrobial peptides (LL-37, Defensins) represent a critical emerging area given antibiotic resistance. Evidence quality varies dramatically.

Obesity & Weight Loss
Obesity (BMI ≥30) affects over 42% of US adults and is associated with T2D, cardiovascular disease, and multiple cancers. The peptide-based GLP-1/GIP drug class has fundamentally changed the treatment landscape since 2021, with multiple FDA-approved agents achieving 15–22%+ weight loss in clinical trials.

Sexual Health & Reproductive Function
Sexual health peptides include the FDA-approved Bremelanotide (PT-141) for HSDD, gonadorelin for hormonal support, and kisspeptin for HPG axis regulation. Evidence ranges from Phase III RCTs to research-stage compounds.

Skin & Aesthetic Medicine
Cosmetic peptides represent the segment with the most consumer marketing and the most variable evidence quality. GHK-Cu is 503A-listed with peer-reviewed clinical trials. Matrixyl/Argireline have published RCTs. Many others have no peer-reviewed human data.
7 peptides →
Tissue Repair & Recovery
Peptide-based tissue repair is one of the most active research areas, with compounds targeting wound healing, tendon repair, muscle recovery, and post-surgical healing. Evidence ranges from Phase II human trials (TB-500, Thymosin Alpha-1) to promising animal models (BPC-157). No FDA-approved peptide exists specifically for tissue repair outside specific niche indications.
