What exactly is GHK-Cu, and where does the 50mg tier fit?
GHK-Cu is a copper-tripeptide — glycyl-L-histidyl-L-lysine chelated to a Cu²⁺ ion — that occurs endogenously in human plasma and drops with age. In pre-clinical research it appears in extracellular-matrix remodeling, wound-healing, and skin-model literature. The 50mg per vial tier is the standard research presentation, suitable for most single-cohort study designs. The 100mg tier (CU100) is the extended-study option when a single reconstitution needs to supply multi-week working stocks.
What does this specific lot’s CoA cover?
Every CU50 lot ships with a batch-specific certificate: reverse-phase HPLC purity by area, mass-spec identity against theoretical mass, and copper stoichiometry disclosed as 1:1 peptide-to-Cu²⁺ — the standard research presentation. The CoA is not a stability panel.
How do I reconstitute a 50mg GHK-Cu vial?
- Wipe the vial stopper with an alcohol swab.
- Draw 2 to 5 mL of bacteriostatic water (working concentration determines exact volume).
- Inject the diluent slowly against the vial wall — do not aim at the peptide cake.
- Swirl gently to dissolve. Do not shake — the copper-peptide complex disperses readily but shaking risks foaming.
- Store the reconstituted vial at 2 to 8 °C. Use within 30 days.
Should I order the 50mg or 100mg tier?
The 50mg tier suits single-cohort study designs and protocol-development work. The 100mg tier (CU100) reduces per-vial reconstitution overhead for extended studies or higher-throughput designs where a single reconstitution supplies multi-week working stocks. Both tiers ship as kits of 10 vials or single vials.
How is GHK-Cu different from adjacent tissue-repair research peptides?
GHK-Cu carries a copper cofactor as an integral part of the molecule — the copper is not a supplement bolted on but a chelated component with distinct redox-active behavior in the extracellular matrix. BPC-157 (BC10) is a synthetic pentadecapeptide from a gastric juice protein; TB-500 (BT10) is a synthetic thymosin beta-4 fragment. The three are frequently studied in adjacent tissue-repair contexts because their reported mechanisms — copper-carrier ECM remodeling, cytoprotection, and angiogenesis — do not overlap.
What ships in the box, and how fast?
- 10 lyophilized GHK-Cu 50mg vials
- 1 lot-specific certificate of analysis (HPLC + MS + copper stoichiometry)
- 1 handling and reconstitution insert
