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.
