Find peptides by
condition.
Eighteen therapeutic categories, each scored by evidence depth and peptide count. Start with the problem space — compounds with the strongest signal for that goal surface first.
Anxiety & Mental Health
Anxiolytic peptides — particularly Selank and Semax from Russian research — offer a theoretically distinct mechanism from benzodiazepines, with documented GABA-A modulation and BDNF effects but limited Western RCT data.
Athletic Performance & Recovery
Performance and recovery applications of research peptides — a category where WADA prohibition status matters, access has shifted significantly post-2023, and evidence quality varies widely.
Cardiovascular Health
Cardiovascular applications span from GLP-1 agonists with landmark outcomes trials to TB-500's cardiac repair data from RegeneRx Phase II trials — with distinct mechanisms and very different evidence quality.
Cognitive Enhancement & Neuroprotection
Peptides with nootropic, anxiolytic, and neuroprotective effects — ranging from Russian-origin compounds with approval in specific countries to theoretical neuroprotective agents with animal-model evidence.
Gut Health & GI Disorders
BPC-157's origins as a gastric pentadecapeptide make GI applications its most mechanistically grounded use case — with strong animal evidence spanning IBD, leaky gut, and gastric ulcers.
Hormone Optimization
Peptides that modulate the growth hormone, sex hormone, and thyroid axes — including secretagogues that preserve endogenous production and compounds used alongside traditional hormone replacement therapy.
Immune Support & Modulation
Thymic peptides and immune-modulating compounds with evidence spanning from approved anti-infective uses to research-stage immunomodulation — a category with unusually strong clinical data in certain regions.
Injury Recovery & Tissue Repair
Peptides for accelerating tissue healing — tendons, ligaments, muscle, gut lining, and cartilage — represent one of the most actively researched areas, though regulatory access to the most studied compounds has narrowed significantly.
Longevity & Healthy Aging
Anti-aging peptide research spans telomerase activation, growth hormone restoration, immune modulation, and cellular repair — all areas of active study with varying levels of evidence.
Sexual Health & Libido
Melanocortin-based and hormonal approaches to sexual dysfunction — PT-141 (bremelanotide) is the only peptide with FDA approval for sexual dysfunction, representing a unique regulatory position in the category.
Skin Health & Hair
GHK-Cu (copper peptide) has the most robust evidence base for skin applications among research peptides — decades of research from Loren Pickart document gene-regulatory effects on collagen, elastin, and wound repair.
Sleep Optimization
Peptide-based approaches to sleep quality, from delta sleep-inducing peptide to GH secretagogues that amplify the nocturnal growth hormone pulse — with a focus on what the evidence actually shows.
Weight Loss & Metabolic Health
Peptide-based approaches to weight management span from FDA-approved GLP-1 agonists with robust clinical evidence to research-stage compounds with preliminary data. The landscape changed dramatically with the approval of semaglutide and tirzepatide.
Evidence quality still varies widely
Some conditions have FDA-approved peptides backed by Phase 3 RCTs. Others have only animal model data. The condition pages are designed to make that difference visible immediately.
Phase III randomized controlled trials with adequate power.
Phase I/II human trials, smaller cohorts, or strong observational data.
Animal models, in vitro work, or limited human evidence.
Anecdotal reports, case studies, or pre-clinical theory.
