Every peptide, A–Z.

Adipotide

Prohibitin-targeting peptidomimetic. Striking primate fat-loss data, and the renal toxicity that stopped it.

5-Amino-1MQ

Small-molecule NNMT inhibitor. Not a peptide, but it lives in the same catalogs and the same conversations.

AOD-9604

The hGH 176-191 fragment. Lipolytic signal without the growth-promoting part of the parent hormone.

Argireline

Acetyl hexapeptide-8. A topical SNARE-complex inhibitor marketed as a needle-free wrinkle treatment.

Bacteriostatic water

0.9% benzyl-alcohol water. The reconstitution diluent — and the single most-searched peptide accessory.

BPC-157

Pentadecapeptide from gastric juice. The most-cited tissue-repair compound in the field, and the one with the thinnest human evidence.

BPC-157 / TB-500 blend

The “Wolverine stack” in a single vial. Two repair mechanisms with no combination trial behind them.

Cagrilintide

Long-acting amylin analog. Interesting alone, far more interesting stacked with semaglutide as CagriSema.

Cartalax

Ala-Glu-Asp-Pro. The cartilage-directed Khavinson bioregulator.

CJC-1295

GHRH analog. The no-DAC form pulses; the DAC form doesn't — and that difference drives everything else.

CJC-1295 / Ipamorelin

GHRH analog plus selective secretagogue — the classic complementary-mechanism GH stack.

DSIP

Delta sleep-inducing peptide. Named for an effect the modern literature has struggled to reproduce cleanly.

Epithalon

Ala-Glu-Asp-Gly. Telomerase claims from Russian trials that have never been independently replicated.

GHK-Cu

Copper tripeptide. The best-evidenced cosmetic peptide there is — and injectable and topical are not interchangeable.

GLOW blend

BPC-157 + TB-500 + GHK-Cu in one vial. Three well-studied constituents, zero trials on the combination.

Glutathione

The master intracellular antioxidant. Redox cycling is well established; the skin-lightening claim is not.

Gonadorelin

Synthetic GnRH. Pulsatile dosing stimulates the axis; continuous dosing shuts it down.

Hexarelin

The most potent GH secretagogue of the ghrelin-mimetic class — and the fastest to desensitize.

IGF-1 LR3

Long-arg3 IGF-1 — an engineered analog with ~100× the free-fraction half-life of native IGF-1.

Ipamorelin

Selective GHS-R agonist — a growth-hormone secretagogue that leaves cortisol and prolactin alone.

KLOW blend

The GLOW trio plus KPV — GHK-Cu, BPC-157, TB-500 and KPV in one 80 mg vial, and no study of any of it together.

KPV

The C-terminal tripeptide of α-MSH. Anti-inflammatory signal in gut and skin models without the pigmentation effect.

Matrixyl

Palmitoyl pentapeptide-4. The other cosmetic workhorse — a matrikine that signals collagen synthesis.

Mazdutide

GLP-1/glucagon dual agonist developed for the Chinese market. Strong Phase 3 weight data, narrow approval.

MOTS-c

Mitochondrial-derived peptide that activates AMPK. The closest thing the field has to an exercise mimetic.

NAD+

The redox cofactor at the center of the longevity conversation. Injectable, IV, and oral-precursor routes all behave differently.

Pinealon

Khavinson tripeptide (Glu-Asp-Arg) aimed at neuronal tissue. Bioregulator theory, thin external evidence.

PT-141

Bremelanotide. MC4R agonist acting in the CNS rather than the vasculature; approved as Vyleesi.

Retatrutide

Triple GIP/GLP-1/glucagon agonist — the most-searched research peptide in the world, and still investigational.

Selank

Tuftsin-derived anxiolytic from the Russian school. GABAergic and BDNF effects without benzodiazepine sedation.

Semaglutide

The GLP-1 analog behind Ozempic and Wegovy — the molecule that started the metabolic-peptide boom.

Semax

ACTH(4-10) fragment. Raises BDNF; used in Russian stroke protocols, unapproved everywhere else.

Sermorelin

GHRH(1-29) — the original secretagogue. Discontinued as a drug, still everywhere as a research compound.

SS-31

Elamipretide. Binds cardiolipin on the inner mitochondrial membrane; has FDA orphan history in Barth syndrome.

Survodutide

Dual GLP-1/glucagon agonist in Phase 3. The glucagon arm is what separates it from tirzepatide.

TB-500

Synthetic thymosin β4 fragment. Actin-sequestering, and almost always discussed alongside BPC-157.

Tesamorelin

Stabilized GHRH analog, FDA-approved as Egrifta for HIV lipodystrophy — the rare peptide with a real label.

Testagen

Lys-Glu-Asp-Gly. Khavinson's testicular-tissue bioregulator.

Thymosin α-1

28-aa immunomodulator, approved in more than 30 countries as Zadaxin. One of the better-evidenced peptides here.

Tirzepatide

Dual GIP/GLP-1 agonist behind Mounjaro and Zepbound. Approved as a drug; sold separately as a research compound.

Vesugen

Lys-Glu-Asp. The vascular-endothelium bioregulator in the Khavinson series.

Vilon

Lys-Glu dipeptide. The thymus-directed bioregulator, and the shortest peptide in this library.
