Research category
UK supplier of five regenerative-research peptides spanning tissue-repair, connective-tissue and immunomodulatory pathways. From the most-cited tendon-research peptide BPC-157 to the copper-binding tripeptide GHK-Cu - the canonical reference catalogue for regenerative-pharmacology research in the UK. Every batch independently HPLC-verified by Janoshik Analytical at 99%+ purity. Research use only - not for human consumption.
The regenerative peptide family is unified by a shared research focus: modulation of tissue-repair, angiogenesis, fibroblast activity, and immunomodulatory signalling. Compounds in this category are studied in published preclinical models for tendon, ligament, gut-mucosal, dermal and connective-tissue repair endpoints. Mechanistically the family spans copper-coordination chemistry (GHK-Cu), nitric-oxide pathway modulation (BPC-157), actin-binding angiogenesis modulators (TB-500), and TLR-9 / immune signalling (Thymosin Alpha-1).
This is one of the most cited research-peptide categories in published literature, with thousands of preclinical papers. The Sikiric group (BPC-157), Pickart and Margolina (GHK-Cu), and Goldstein (Thymosin Alpha-1) reviews are the canonical reference summaries.
| Compound | Class | Residue count | Primary research focus |
|---|---|---|---|
| BPC-157 | Pentadecapeptide (gastric protein fragment) | 15 | Tendon / gut / connective tissue |
| TB-500 | Thymosin β4 fragment | 17 | Angiogenesis / actin-binding |
| GHK-Cu | Copper tripeptide complex | 3 + Cu²⁺ | Collagen / dermal / antioxidant |
| Thymosin Alpha-1 | Acetylated 28-AA peptide | 28 | Immunomodulation / TLR-9 |
| KLOW Blend | Proprietary regenerative blend | Multiple | Composite tissue research |
BPC-157 (Body Protection Compound 157) is a synthetic 15-amino-acid sequence (GEPPPGKPADDAGLV) identified within human gastric juice protein. Its defining feature is unusual stability in acidic conditions, characterised across decades of preclinical literature led by the Sikiric group. Mechanism includes nitric-oxide synthesis modulation, growth-hormone receptor expression in fibroblasts, and angiogenic markers.
GHK-Cu is the smallest peptide in this category - just three residues (Gly-His-Lys) bound to a Cu²⁺ ion. The Pickart 2018 review surveys ~600 published studies in dermal-fibroblast, collagen-synthesis and antioxidant-pathway research. The copper coordination is essential to the bioactive complex.
For a direct comparison, see GHK-Cu vs BPC-157.
BPC-157 and TB-500 are the two most-cited references. BPC-157 dominates the literature for gut-research and tendon repair; TB-500 leads in actin-binding and angiogenesis-pathway research.
GHK-Cu is the canonical reference for collagen-synthesis and dermal-fibroblast research. The bound copper is essential to the studied chemistry.
Thymosin Alpha-1 is the canonical reference for TLR-9 / innate immunity research. Approved in some jurisdictions; widely used as a research reference.
The KLOW Blend is supplied for researchers needing a multi-peptide composite reference in a single vial. See product page for compositional notes.
All compounds in this category are supplied as lyophilised powder in sealed glass vials. Reconstitute with bacteriostatic water added slowly down the side wall, swirling gently. GHK-Cu is light-sensitive - store in amber containers and protect from prolonged light exposure.
Compounds in this category are independently HPLC-verified by Janoshik Analytical at 99%+ purity. Where a Janoshik report has been issued for the current batch it is supplied with the order, and verification records are published on the Purity page.
