How is GHK-cu Pen stored and handled?
Storage
Store the pen at -20°C, protected from light. Once reconstituted or in use, refrigerate at 2-8°C and keep the cap on.
Pen needles
Pen needles are not included. Use a fresh standard 31G pen needle for every draw and remove it after use so the cartridge stays sealed.

All research guides- What is GHK-Cu? A Plain Explanation of the Copper PeptideGHK-Cu is the copper complex of the tripeptide glycyl histidyl lysine, a sequence found naturally in human plasma. It is studied in dermal fibroblast, collagen synthesis and matrix remodelling models, where the bound copper ion is treated as part of the active species. It is supplied at high vial mass, so concentration must be recalculated rather than copied from a 10mg peptide.5 min read
- How to Store and Handle Research PeptidesLyophilised research peptides are stored in the refrigerator at 2 to 8 °C, or frozen at -20 °C for longer storage, sealed and protected from light. After reconstitution with [bacteriostatic water](/product/bacteriostatic-water-10ml) the solution is kept refrigerated, never shaken, and never refrozen.5 min read
- How to Read a Peptide COA (Certificate of Analysis)A peptide certificate of analysis shows what an independent laboratory found in one specific batch: identity confirmed by mass spectrometry, purity measured by HPLC, and the measured quantity against the labelled amount. Read it by checking the batch reference against your vial first, then the identity result, then the purity figure and the test date.6 min read
- GHK-Cu vs AHK-Cu: Two Copper Peptides ComparedGHK-Cu is the copper complex of the tripeptide glycyl histidyl lysine, a naturally occurring human plasma peptide with a large preclinical literature in skin and connective tissue models. AHK-Cu is the copper complex of alanyl histidyl lysine, a related but far less studied tripeptide that appears mostly in hair follicle and dermal cell work.6 min read
- What your vial should look likeA sealed research peptide vial normally holds a white to off-white lyophilized cake or powder under an intact stopper and crimp cap. Pre-filled pens and nasal spray kits arrive sealed, with their documented appearance on the product page. Appearance never proves identity or purity; the COA for the batch does.4 min read
