GHK-Cu and TB-500: UK Research Supply Reference (2026)

GHK-Cu and TB-500: UK Research Supply at a Glance

Peptify UK (PEPTIFY LIMITED, Companies House #17021295) supplies GHK-Cu and TB-500 as research-use-only peptides, each dispatched from London with a per-batch Certificate of Analysis produced by Janoshik Analytical, an independent Czech laboratory.\n\nBoth compounds sit in the restoration group of the Peptify UK catalogue. This reference sets out what each peptide is, the research pathways examined in the published literature, and the verifiable supply facts a UK laboratory needs before ordering.\n\nEvery batch of both peptides links to a downloadable COA on its product page at peptifyuk.com, showing the HPLC chromatogram and the batch identifier printed on the vial. GHK-Cu is supplied to a 99%+ HPLC-verified purity specification; TB-500 is supplied to an honest 98%+ HPLC-verified specification, reported per batch rather than rounded up. Both ship by Royal Mail Tracked, with same-day dispatch on orders placed before 1pm Monday to Friday and free UK delivery over £40. All material is sold strictly for in-vitro and laboratory research and is not intended for human consumption.

What Is GHK-Cu?

GHK-Cu is a copper-binding tripeptide (glycyl-L-histidyl-L-lysine complexed with copper) that has been studied in the scientific literature since the 1970s. Peptify UK supplies it as a 50mg research vial at £18.99, HPLC-verified to a 99%+ purity specification with a per-batch Janoshik COA.\n\nThe compound was first described in research on the copper-binding fraction of human plasma, and the published literature has examined it across several distinct pathways. Reported research areas include:\n\n- Collagen-synthesis research, where the tripeptide has been investigated in dermal fibroblast models in vitro.\n- Extracellular-matrix research, where studies have examined matrix-associated markers in cultured cells.\n- Antioxidant-gene-regulation research, where published work has examined the modulation of gene expression associated with oxidative-stress response.\n- Copper-transport research, where the peptide's role as a carrier of copper ions has been studied at the cellular level.\n\nThese are descriptions of research areas found in the peer-reviewed literature, not statements of outcome. GHK-Cu is provided for laboratory investigation only, and nothing here should be read as guidance for any use outside a controlled laboratory setting.

What Is TB-500?

TB-500 is a synthetic peptide corresponding to an active fragment of thymosin beta-4 (Tβ4), a 43-amino-acid protein present in most cell types. Peptify UK supplies TB-500 as 5mg and 10mg research vials, HPLC-verified to an honest 98%+ purity specification with a per-batch Janoshik COA.\n\nThymosin beta-4 is a primary actin-sequestering molecule, and the published literature has examined the TB-500 fragment across several research pathways. Reported research areas include:\n\n- Cell-migration research, where the peptide has been studied in relation to actin dynamics in cultured cells.\n- Angiogenesis research, where published work has examined vascular endpoints in preclinical models.\n- Cell-differentiation research, where studies have examined cellular markers across multiple tissue types in vitro and in vivo.\n- Inflammatory-marker research, where the literature has examined modulation of cytokine expression.\n\nThese descriptions reflect the direction of published investigation, not any claimed effect. TB-500 is supplied for research use only. The 98%+ specification is reported honestly per batch rather than inflated; a batch that falls below the stated specification at intake is rejected. The COA for each lot documents the actual measured purity for that specific batch.

Purity Specifications and the Per-Batch COA

Every GHK-Cu and TB-500 batch supplied by Peptify UK is tested by Janoshik Analytical, an independent third-party laboratory, and each lot carries its own downloadable Certificate of Analysis. Independent, per-batch testing is the single most important verification step when sourcing research peptides in the UK.\n\nThe distinction between the two purity figures is deliberate and honest. GHK-Cu is verified to a 99%+ HPLC purity specification. TB-500 is verified to a 98%+ HPLC specification, a figure reported truthfully rather than rounded to 99% for marketing symmetry. Reporting the genuine per-batch number matters more for research reproducibility than presenting a uniform headline figure.\n\nA compliant COA for either peptide should show:\n\n- The batch or lot number, matching the number printed on the vial.\n- The HPLC chromatogram, with the main peak clearly identified.\n- The measured purity percentage for that specific batch.\n- Mass-identification data confirming the peptide's molecular weight.\n- The name of the testing laboratory (Janoshik Analytical) and the test date.\n\nResearchers should always cross-check the lot number on the received vial against the COA published on the product page. If a supplier cannot provide an independent, batch-specific COA, the material's purity is unverifiable and should not be relied upon for research.
