Which vial size should I order?
| Vial size | Reconstitution volume | Concentration @ 2 mL BAC | Use case |
|---|---|---|---|
| 50mg (CU50) | 1-2 mL BAC water | 25 mg/mL | Small cohorts, protocol dev |
| 100mg (CU100) | 1-2 mL BAC water | 50 mg/mL | Higher-throughput designs |
What exactly is GHK-Cu, and why is a copper tripeptide interesting for extracellular-matrix research?
GHK-Cu is a copper-binding tripeptide — glycyl-L-histidyl-L-lysine complexed with a divalent copper ion (Cu²⁺). The peptide sequence occurs endogenously in human plasma, and the copper cofactor is what distinguishes the loaded complex from the apo-peptide. Every lot is assayed by HPLC (purity) and mass spectrometry (identity).

In the pre-clinical literature, GHK-Cu is one of the most extensively studied copper-carrier tripeptides. Reported activity spans extracellular matrix remodeling, wound-healing models, angiogenic and antioxidant activity, and dermal / hair-follicle cell models. It is commonly paired with tissue-repair peptides such as BPC-157 in combinatorial pre-clinical designs.
Prescott Bio supplies GHK-Cu in 50mg and 100mg vial sizes so researchers can match presentation to cohort size and dose-response design. Certificates of analysis are batch-specific and available on request via the /coa lookup. All product is sold strictly for laboratory research use only.

Questions Canadian labs ask before their first order
-
What exactly is GHK-Cu?
GHK-Cu is a copper-binding tripeptide — the sequence glycyl-L-histidyl-L-lysine (GHK) complexed with a divalent copper ion (Cu²⁺). The peptide occurs endogenously in human plasma; the copper cofactor is what distinguishes the loaded complex from the apo-peptide. Prescott Bio supplies GHK-Cu as a lyophilized copper-loaded tripeptide, characterised by its blue tint on reconstitution. -
50mg vs 100mg — which vial size should I choose for research?
The 50mg presentation suits smaller-cohort work and shorter dose-response windows, and gives a lower per-vial working stock so reconstituted material is used within the 30-day stability window. The 100mg presentation cuts per-vial reconstitution overhead for higher-throughput designs and pre-clinical cohorts running longer arms. Both ship in kits of 10 vials and come from the same synthesized lots. -
How is GHK-Cu reconstituted?
- Wipe the vial stopper with an alcohol swab.
- Draw the target volume of bacteriostatic water (typically 1-2 mL).
- Inject the diluent slowly against the vial wall — do not aim at the peptide cake.
- Swirl gently to dissolve. Do NOT shake. The characteristic blue tint indicates the copper complex is intact.
- Store the reconstituted vial at 2-8°C. Use within 30 days.
-
How is GHK-Cu stored?
- Refrigerate lyophilized vials at 2-8°C until first use.
- After reconstitution with bacteriostatic water, store at 2-8°C and use within 30 days.
- For storage beyond six months, freeze the sealed lyophilized vial at -20°C.
- Avoid repeated freeze-thaw cycles.
-
How fast does Prescott Bio ship?
Orders placed before 14:00 PT ship the same business day from our British Columbia facility. Canadian orders arrive 2-4 business days after dispatch. -
Does the CoA report the copper content or just the peptide sequence?
The CoA reports HPLC purity by area and mass-spec identity of the peptide, which confirms the peptide component. Copper content is disclosed as stoichiometric (1:1 peptide-to-copper) — the standard research presentation.
