Peptides are short chains of amino acids, the body's native signaling molecules. Where hormones broadcast, peptides whisper. They tell specific cells to repair, regenerate, secrete, or stand down. Modern peptide therapeutics are precision tools: GLP-1 agonists for metabolic recalibration, growth-hormone secretagogues for tissue maintenance, healing peptides for repair, neuropeptides for cognition and mood. The compounds below are organized by their primary axis of action.
GLP-1 & Metabolic.
Incretin mimetics and metabolic-axis compounds. The new class of fat-loss and glucose-control therapeutics.
5-Amino-1MQ
Small-molecule NNMT inhibitor. Targets the NAD+/methylation pathway for fat loss and stem cell maintenance.
Cagrilintide
Long-acting amylin analog. Slows gastric emptying, increases satiety. Often paired with semaglutide as CagriSema.
MOTS-c
Mitochondrial-derived peptide. AMPK activator and metabolic flexibility agent.
AOD-9604
Modified GH fragment. Stimulates lipolysis without affecting glucose or IGF-1.
Retatrutide
Triple agonist. GIP, GLP-1, and glucagon receptors.
Semaglutide
GLP-1 receptor agonist. Appetite, satiety, insulin sensitivity.
Tirzepatide
Dual GIP/GLP-1 agonist. Glycemic control and fat-mass attenuation.
Growth Hormone.
Secretagogues and releasers that signal the pituitary. Axis maintenance, body composition, sleep architecture.
MK-677 (Ibutamoren)
Oral ghrelin mimetic. Sustained GH/IGF-1 elevation without injection.
Hexarelin
Potent GHRP. Notable for cardioprotective effects beyond GH release.
Sermorelin
The original GHRH (1-29) analog. Foundation of the modern GH-axis stack.
Tesamorelin
GHRH analog with strong specificity for visceral fat reduction.
CJC-1295
GHRH analog. Increases GH and IGF-1. Available with or without DAC.
Ipamorelin
GH secretagogue. Pulsatile GH release without cortisol or prolactin elevation.
Recovery & Repair.
Healing peptides for soft tissue, gut lining, vascular repair. The rebuild stack.
Cosmetic & Skin.
Topical and systemic peptides for skin, hair, and tone. Lineup expanding.
Argireline (Acetyl Hexapeptide-3)
Topical SNAP-25 modulator. The 'Botox in a bottle' claim. Modest but measurable.
Matrixyl (Palmitoyl Pentapeptide-4)
Collagen synthesis signal for topical use. Anti-aging skincare workhorse.
Melanotan II
α-MSH analog. Tanning, plus libido side effects (the predecessor to PT-141).
GHK-Cu
Copper peptide. Skin quality, hair growth, anti-aging.
Cognitive & Emotional.
Neuropeptides for focus, mood regulation, sleep, and stress response.
Longevity & Immune.
Thymic factors and bioregulators. The slow-axis tools: telomeres, immunity, healthspan.
Humanin
Mitochondrial-derived peptide. Cytoprotection and the metabolic-aging axis.
Thymosin Alpha-1
Polypeptide hormone. Immune modulation and T-cell function.
Epitalon
Tetrapeptide. Telomerase activity and pineal regulation.
NAD+
Mitochondrial currency. The compound that runs underneath everything else.
Sexual Wellness.
Melanocortin and reproductive-axis peptides. Libido, response, and the HPG.
