Copper-peptide and dermatological-research reference compounds for in-vitro and extracellular-matrix study. COA-backed, lyophilized, and shipped from the USA.
The Cosmetic & Blends category focuses on copper peptides and multi-peptide reference blends studied in dermatological and extracellular-matrix (ECM) research. These are laboratory research reagents supplied for in-vitro and preclinical work. For research use only — not for human consumption. Nothing here describes a cosmetic, skincare or personal-care use; the summaries reflect only how these compounds appear in the research literature.
GHK-Cu is a copper-binding tripeptide (glycyl-L-histidyl-L-lysine complexed with copper) that has been investigated in research models of extracellular-matrix remodeling, fibroblast activity and collagen-related signaling. It is the anchor reference compound of this category and a common standard in copper-peptide assays. Labs that buy GHK-Cu for research value a lot-verified powder they can qualify by COA.
The Glow Blend combines complementary peptides in a single lyophilized vial for study designs that examine synergy across dermatological-research targets. Its exact composition is listed on the product page and reflected on the lot COA.
The Klow Blend is a related multi-peptide reference material formulated for comparative ECM and skin-model research. As with all blends, each component is documented so results stay attributable, and the ratio of constituents is fixed per lot so repeat orders behave consistently across a study series.
Blends raise the bar on verification because more than one sequence must be confirmed. Each lot is independently tested — HPLC for purity against our ≥99% target and mass spectrometry for identity of the constituents — and reported on a batch-specific Certificate of Analysis. Every vial is traceable to its source lot. If a blend's COA is unfamiliar territory, the COA reading guide explains how to read multi-component results so each peptide can be accounted for.
Copper peptides and blends ship as lyophilized powder and remain stable kept cold, sealed and away from light. GHK-Cu in particular should be protected from prolonged light exposure once in solution, and all reconstituted material is best aliquoted to avoid repeated freeze-thaw. Use the reconstitution guide for solvent selection and the storage & handling page for cold-chain practice. Reconstitution supplies are in our supplies category.
We ship research-grade cosmetic-research peptides from the USA with a COA on every batch, transparent sourcing and full lot traceability. Handling runs 1–2 business days and delivery 2–5, all priced in USD; orders over $75 ship free while a flat $12 applies below that. Offline payment is available by crypto, bank transfer, Zelle, Cash App and Venmo, and first-time buyers save 15% with LAB15.
GHK is a tripeptide that binds copper ions; the complex is what is studied in ECM-remodeling research models.
Each is a distinct multi-peptide reference material with its own documented composition — see the individual product pages and their COAs.
No. They are research chemicals for laboratory study only and are not cosmetics, skincare or products intended for human use in any form.
Each lot is made to a fixed formulation and documented on its own COA, so you can confirm the constituents match your previous order before you rely on it.
