Peptide Arcana

Every peptide, Unforgettable.

Learn what each peptide does, remember it with one image, understand where it acts.

Bremelanotide: For low desire: it switches on MC4 receptors in your brain, so it works on wanting, not plumbing. Candlelight for the hypothalamus.Insulin: Binds insulin receptors on muscle, fat and liver so they pull glucose from the blood. Analogs come fast for meals or slow all day.LL-37: An antibiotic your skin and white cells cut from cathelicidin; vitamin D turns its gene on. Sold for infections and wounds.Vasopressin: Hits V1 receptors to constrict blood vessels and V2 receptors so the kidneys hold water: a drip to lift blood pressure in shock.Semaglutide: GLP-1, a gut hormone, on a weekly contract: it slows your stomach and tells your brain 'we're full' before the second plate.Oxytocin: Contracts the myometrium, the uterine muscle, to drive labor and stop bleeding after birth. Online it's also sold as a love spray.TB-500: Thymosin beta-4's actin-grabbing stretch; actin is the filament cells crawl with. Sold to speed muscle and tendon repair.GHK-Cu: GHK, three amino acids found in blood, clasping a copper atom; in serums, meant to spur fibroblasts, the skin's collagen makers.

The 22 best known

The peptides everyone is talking about, from the GLP-1s to the gym vials.

  • The FoolBPC-157: Fifteen amino acids said to come from a gastric juice protein, sold to speed the repair of tendons, muscle and the gut lining.
  • The MagicianInsulin: Binds insulin receptors on muscle, fat and liver so they pull glucose from the blood. Analogs come fast for meals or slow all day.
  • The High PriestessEpitalon: A four-amino-acid pineal peptide sold for longevity, meant to activate telomerase, the enzyme that rebuilds chromosome tips.
  • The EmpressOxytocin: Contracts the myometrium, the uterine muscle, to drive labor and stop bleeding after birth. Online it's also sold as a love spray.
  • The EmperorTeriparatide: A daily pulse of parathyroid hormone's active end, spurring osteoblasts, the cells that lay down bone. For osteoporosis.
  • The HierophantThymosin Alpha-1: From the thymus, where T cells mature: a peptide meant to boost them, given for hepatitis B and weak flu-shot responses.
  • The LoversBremelanotide: For low desire: it switches on MC4 receptors in your brain, so it works on wanting, not plumbing. Candlelight for the hypothalamus.
  • The ChariotTirzepatide: Two gut-hormone receptors, GIP and GLP-1, in one weekly shot: insulin rises with sugar, appetite drops. For diabetes and obesity.
  • StrengthLL-37: An antibiotic your skin and white cells cut from cathelicidin; vitamin D turns its gene on. Sold for infections and wounds.
  • The HermitHumanin: Found in an Alzheimer's brain while hunting what spared its neurons: a peptide coded by mitochondrial DNA, sold for longevity.
  • Wheel of FortuneKisspeptin-10: The active end of kisspeptin, which wakes GnRH neurons, the brain's master switch for sex hormones. Sold to raise testosterone.
  • JusticeVasopressin: Hits V1 receptors to constrict blood vessels and V2 receptors so the kidneys hold water: a drip to lift blood pressure in shock.
  • The Hanged ManZiconotide: Cone snail toxin that blocks N-type calcium channels, which pain nerves use to relay signals. Infused in the spine for severe pain.
  • DeathLutetium-177 Dotatate: Docks on the somatostatin receptors of hormone-making gut tumors, delivering lutetium-177, whose beta rays damage them up close.
  • TemperanceSemaglutide: GLP-1, a gut hormone, on a weekly contract: it slows your stomach and tells your brain 'we're full' before the second plate.
  • The DevilMelanotan II: Copies alpha-MSH, the skin-darkening hormone, at melanocortin receptors in skin and brain: sold for a sunless tan, plus libido.
  • The TowerRetatrutide: One molecule, three receptors: GLP-1 and GIP to curb appetite, glucagon to burn energy and pull fat out of the liver.
  • The StarGHK-Cu: GHK, three amino acids found in blood, clasping a copper atom; in serums, meant to spur fibroblasts, the skin's collagen makers.
  • The MoonDSIP: Named for delta sleep, the deepest stage: nine amino acids from sleeping rabbits' blood, gene unknown. Sold for sleep and stress.
  • The SunMOTS-c: Coded in mitochondrial DNA, it rises in muscle during exercise; sold as exercise in a vial, meant for fat loss and blood sugar.
  • JudgementGallium-68 Dotatate: Carries gallium-68 to somatostatin receptors on hormone-making gut tumors so they glow on a PET scan, flagging who gets lutetium.
  • The WorldTB-500: Thymosin beta-4's actin-grabbing stretch; actin is the filament cells crawl with. Sold to speed muscle and tendon repair.
