The UK reference on healing & regeneration research peptides

Body Protection Compound 157 · PL 14736 · Pentadecapeptide BPC 157

A 15-amino-acid pentadecapeptide derived from a protective protein found in human gastric juice. The most-studied healing research peptide, with extensive pre-clinical work on tendon, ligament, gut, and vascular repair.

Thymosin Beta-4 fragment · Tβ4 17-23 · TB500

A synthetic peptide commonly described as a fragment of thymosin beta-4 incorporating the actin-binding 'LKKTETQ' motif. Studied for soft-tissue repair, wound healing, and cardiac tissue regeneration in animal models.

Copper tripeptide-1 · Glycyl-L-histidyl-L-lysine:copper(II)

A naturally occurring copper-binding tripeptide (Gly-His-Lys) complexed with Cu(II). Extensively studied in dermatology for wound healing, collagen synthesis, antioxidant defence, and hair-follicle stimulation.

α-MSH 11-13 · Lysine-Proline-Valine tripeptide

A three-amino-acid C-terminal fragment of α-MSH studied for its anti-inflammatory effects in colitis, atopic skin conditions, and mucosal healing models — without the pigmentary effects of full-length MSH.

Cathelicidin LL-37 · hCAP-18 fragment

The only human cathelicidin antimicrobial peptide — a 37-residue cationic helix studied for direct antimicrobial action, wound healing, angiogenesis, and modulation of host immune responses.

Tβ4 · TMSB4X · Full-length thymosin beta-4

A 43-amino-acid actin-sequestering peptide expressed in nearly all human cells. Distinct from the shorter TB-500 fragment; investigated in cardiac repair, corneal healing, and dermal regeneration.
