What exactly is GHK-Cu, and why do research programs pick the 100mg tier?
GHK-Cu is the copper-bound form of the tripeptide glycyl-L-histidyl-L-lysine (Gly-His-Lys) complexed with a Cu²⁺ cofactor. It has been studied for decades in pre-clinical wound-healing, extracellular-matrix (ECM) remodeling, and hair-follicle regeneration models. The 100mg per vial tier is the high-mass option in the Prescott catalogue — suited to extended topical formulations, bulk carrier-solution work, or multi-week reconstituted stocks where a smaller vial would force frequent re-mixing.
What does this specific lot’s CoA cover?
Every GHK-Cu lot is analysed by reverse-phase HPLC for peptide purity and by mass spectrometry to confirm the expected Gly-His-Lys + Cu²⁺ mass profile. Lot-specific certificates of analysis are being catalogued and will appear on the product page as they come online.
How do I reconstitute a 100mg GHK-Cu vial?
- Warm the vial to room temperature and sanitize the stopper with an alcohol swab.
- Draw 1 to 2 mL of bacteriostatic water — GHK-Cu dissolves rapidly and yields a characteristic blue solution.
- Introduce the diluent slowly against the glass wall so the lyophilized cake wets gradually.
- Roll the vial gently; the blue colour confirms the copper complex is intact.
- Hold at 2 to 8 °C and use the reconstituted vial within 30 days.
GHK-Cu 100mg vs the 50mg CU50 tier
CU50 is the lower-mass sibling for programmes that only need a single working concentration or short study window. CU100 doubles the peptide mass per vial, which cuts per-vial reconstitution overhead in half for identical carrier volumes and is preferred when a laboratory is preparing bulk topical vehicles or extended in-vitro incubations.
How does GHK-Cu compare with other ECM-remodeling peptides?
Unlike the pentadecapeptide BPC-157, which is studied for cytoprotective signalling, GHK-Cu carries a bound copper cofactor that participates directly in ECM enzyme activity. It is often paired with keratin-tropic peptides such as KPV in follicle and dermal-model designs where copper-dependent and copper-independent signalling arms are compared side by side.
