BPC-157

Body Protection Compound-157

Cat 1 — 2026
injectableoral
Evidence

15-amino acid peptide derived from human gastric juice. Promotes tissue repair, gut healing, and angiogenesis. Among the most-researched repair peptides available.

Thymosin Alpha-1

Tα1 / Thymalfasin / Zadaxin

Cat 1 — 2026
injectable
Evidence

28-amino acid immune-modulating peptide derived from the thymus gland. Approved in 70+ countries as Zadaxin. Among the most clinically validated peptides globally.

Wolverine Stack

BPC-157 / TB-500 Combination / Recovery Stack

Cat 1 — 2026
injectable
Evidence

The most researched tissue repair combination in peptide science. BPC-157 and TB-500 work through complementary mechanisms — local repair signaling and systemic actin regulation — making them the gold standard recovery stack.

KPV

Lys-Pro-Val tripeptide / α-MSH fragment

Cat 1 — 2026
injectableoral
Evidence

Tripeptide fragment of alpha-MSH with potent gut anti-inflammatory effects. One of the few peptides with genuine oral bioavailability making it uniquely valuable for gut-specific research.

VIP

Vasoactive Intestinal Peptide

RUO only
nasalinjectable
Evidence

28-amino acid neuropeptide with remarkable anti-inflammatory lung-protective and cognitive properties. Significant research interest for Long COVID and chronic inflammatory response syndrome.

LL-37

Cathelicidin / hCAP-18 fragment

RUO only
injectabletopical
Evidence

Human host defense peptide with broad-spectrum antimicrobial and wound-healing properties. Naturally produced by immune cells. Dual antimicrobial plus healing mechanism is unique.

ARA-290

Cibinetide / Innate Repair Receptor agonist / IRR agonist

RUO only
injectable
Evidence

A synthetic 11-amino acid peptide derived from erythropoietin (EPO) that selectively activates the Innate Repair Receptor (IRR) without stimulating red blood cell production. Studied for neuropathic pain, small fiber neuropathy, sarcoidosis, and metabolic syndrome. Has completed Phase II human trials. Genuinely interesting evidence profile for a non-hematopoietic EPO derivative.

Glutathione

GSH / gamma-Glutamylcysteinylglycine / The master antioxidant

RUO only
injectableoralnasal
Evidence

The body's master antioxidant — a tripeptide naturally produced in every cell, responsible for neutralizing free radicals, supporting detoxification, and regulating immune function. Levels decline with age and under chronic stress. Among the most researched compounds in this database with genuine human clinical trial data across multiple conditions. IV glutathione is widely used in longevity and integrative medicine clinics.
