What are you researching?
Pick a goal. We'll show which peptides have the strongest evidence for it, which are worth watching, and which to treat with caution — so you don't start from 50 cards.
Peptides studied for appetite, incretin biology, and metabolic regulation. Some are approved drugs; others are investigational or speculative.
8 compounds →
Healing / tissue repairCompounds studied for tissue repair, angiogenesis, and protection — largely in animal models. Human evidence is generally limited.
5 compounds →
Skin / hair / cosmeticPeptides studied mostly in topical/cosmetic contexts for skin and collagen biology.
4 compounds →
Growth hormone axisPeptides that influence growth-hormone release (GHRH analogs and ghrelin-receptor agonists) and the IGF-1 axis.
11 compounds →
Longevity / mitochondrialMitochondria-derived and longevity-associated research peptides — among the most hype-prone and least clinically validated.
6 compounds →
Cognitive / focusNeuropeptides studied for cognition, mood, and neuroprotection; human evidence varies and is often limited.
4 compounds →
SleepPeptides discussed for sleep and calm; evidence is limited and early.
2 compounds →
Libido / sexual healthPeptides acting on melanocortin and reproductive pathways; includes one approved agent for a specific indication.
4 compounds →
Immune / inflammationThymic, antimicrobial, and immune-modulating peptides studied for immune activity and inflammation.
4 compounds →
Liver fat / MASHCompounds studied for hepatic fat and metabolic-liver outcomes, mostly within metabolic-drug programs.
3 compounds →
Sports / performance (caution)Frequently discussed for recovery and performance, but largely preclinical and often prohibited in sport.
