Peptides by category
Start from the goal rather than the molecule. Each hub ranks its peptides by how much indexed research actually exists — so a short list is a finding, not an omission.
Research-backed peptides for weight loss and fat reduction. GLP-1 agonists, amylin analogs, and GH-axis peptides compared with mechanism, dosing, and study data.
Peptides studied for muscle hypertrophy, strength, and recovery. GH secretagogues, IGF-1 analogs, and myostatin inhibitors with mechanism, dosing, and study data.
Peptides studied for soft-tissue repair, tendon and ligament recovery, and post-injury healing. BPC-157, TB-500, GHK-Cu, and more — with research data.
Peptides studied for skin regeneration, wrinkle reduction, and dermal repair. Copper peptides (GHK-Cu, AHK-Cu), Argireline, Matrixyl, SNAP-8, and more.
Peptides studied for sleep quality, deep sleep, and circadian regulation. DSIP, Pinealon, Epitalon, and GH-axis peptides with research data.
Peptides studied for longevity, cellular aging, telomere maintenance, and senescence. Epitalon, NAD+, Glutathione, SS-31, FOXO4-DRI and more.
Peptides studied for memory, focus, neuroprotection, and synaptic plasticity. Semax, Selank, Cerebrolysin, Dihexa, P21 and more.
Peptides studied for libido, sexual dysfunction, fertility, and reproductive hormone modulation. PT-141, Kisspeptin, HCG, Gonadorelin and more.
Peptides studied for immune modulation and inflammation control. KPV, Thymosin Alpha-1, LL-37, Thymulin, Thymalin and more.
Peptides studied for metabolic health, glucose regulation, mitochondrial function, and energy. NAD+, MOTS-c, SS-31, AICAR, GLP-1 agonists.
Peptides studied for joint pain, tendon and ligament repair, and connective-tissue regeneration. BPC-157, TB-500, GHK-Cu, MGF, Cartalax.
Peptides studied for hair follicle stimulation and hair regrowth. AHK-Cu (Copper Tripeptide-3), GHK-Cu, Thymulin and more.
Peptides studied for energy, mitochondrial function, exercise capacity, and athletic performance. NAD+, MOTS-c, AICAR, L-Carnitine, SLU-PP-332.
Peptides studied for anti-aging — telomerase, mitochondrial repair, senescence, and skin/cellular renewal. Epitalon, NAD+, GHK-Cu, SS-31, FOXO4-DRI.
A peptide appears in a hub when its category tags match, and only when its profile has a written summary — stub pages are excluded here and from search engines. Counts move as the Librarian files new work. For educational and research purposes only; not medical advice.
