GHK-Cu 50/100mg
50 / 100 mg · Lyophilized
GHK-Cu is a copper-associated tripeptide sequence widely referenced as a laboratory standard in peptide and matrix research. This 50 mg lyophilized format is packaged for traceable handling with batch documentation available through our verification portal. For in vitro research use only — not for personal, cosmetic, or consumptive application.

GHK-Cu Raw Powder
1 g / 20 g · Raw powder
GHK-Cu (copper tripeptide-1; CAS 89030-95-5; C₁₄H₂₂CuN₆O₄; MW 403.92 g/mol) in a 20 g sealed raw-powder research format for high-throughput and multi-assay laboratory programmes that prefer bulk copper-tripeptide stock over repeated vial replenishment. Chemically the same Gly-His-Lys copper(II) complex as our lyophilized vial line, cataloged as an independent presentation family with its own lot documentation — never interchangeable with 50/100 mg vial certificates. Correctly complexed material is visibly blue-green; colour loss on receipt is a reason to pause and check the published COA before the lot enters an experiment. Strictly for qualified in vitro analytical research — not for human, personal, cosmetic, medical, or consumptive application.

Compound identity
GHK-Cu is the copper(II) complex of glycyl-L-histidyl-L-lysine (copper tripeptide-1). Catalog identifiers used across VaultLabs presentations include CAS 89030-95-5, molecular formula C₁₄H₂₂CuN₆O₄, and molecular weight 403.92 g/mol. The sequence is Gly-His-Lys with a coordinated copper centre — not a simple mixture of free peptide and copper salt.
A correctly complexed lot is visibly blue-green. That colour comes from the metal complex itself. White or off-white material is a reason to pause receiving qualification and compare the physical lot against its published certificate before the material enters an experiment.

Raw powder vs lyophilized vials
VaultLabs lists GHK-Cu in two presentation families. Lyophilized vials (50 mg and 100 mg) suit defined single-unit assay work with a fixed nominal mass per sealed vial. Raw powder (1 g and 20 g) is a separate catalog line for laboratories that need bulk copper-tripeptide reference material without repeated vial replenishment.
Both families share the same compound identity and independent lot documentation. A certificate published for a lyophilized lot does not transfer to a raw-powder lot, and the reverse is also true. Procurement records should treat them as related but non-interchangeable catalog lines.
Choosing 1 g, 20 g, or vials
Use vial strengths when your protocol calls for a sealed unit with a fixed nominal mass per container and minimal weighing steps. Choose 1 g raw powder when the laboratory prepares larger working stocks under institutional weighing SOP and has outgrown routine vial replenishment. Choose 20 g when high-throughput or multi-assay programmes prefer fewer open events on parent stock.
Neither format is a cosmetic, supplement, or medicine. VaultLabs supplies both families strictly for in vitro laboratory and analytical research. Format choice is an inventory and workflow decision — not a claim about biological performance.
Analytical qualification notes
Published COA records for GHK-Cu raw powder typically report HPLC purity for the peptide component, with a ≥99% purity target on certificates when testing for that lot is live. HPLC purity alone does not confirm copper stoichiometry.
Laboratories that depend on the complex remaining intact should plan confirmatory checks appropriate to their instrumentation — UV-visible absorbance in the copper d-d region and mass spectrometry are routine choices in the copper-peptide literature. Enter the lot number in the VaultLabs batch verification tool rather than relying on a forwarded email attachment.
Moisture, weighing, and Gulf storage
Keep sealed GHK-Cu raw powder at 2–8 °C, protected from light and humidity. Allow the closed container to reach ambient temperature before opening so moisture does not condense onto the powder — especially important in UAE receiving and weighing rooms.
Weigh promptly under controlled conditions, then aliquot into campaign or single-use portions so the parent stock is not repeatedly exposed. Acidic diluents and strong chelators can demetallate the complex after dissolution; confirm buffer composition before preparation. Document first-open and aliquot dates in institutional logs.
