COA PublishedWhat's in the Vial
GHK-Cu is a copper complex — use sterile water or phosphate-buffered saline (PBS). Do not use acidic solvents. Refrigerate at 2–8 °C after reconstitution; use within 21 days. The solution will appear light blue-green.
General Protocol Ranges
These are published research ranges — not a prescription. Your physician finalizes your protocol.
Research models typically use 0.5–2 mg per injection, daily or every other day, topically or subcutaneously depending on the tissue target. Dose varies substantially based on endpoint (skin, neural, systemic).
Why Physician Oversight?
SourcePeptideCo does not dispense research-grade peptides without licensed physician oversight. This isn't a formality — these compounds interact with individual biochemistry in ways that require clinical judgment.
Our process: you submit a consultation intake, a coordinator matches you with a licensed physician in your state within one business day, and the physician designs a protocol appropriate to your research goals and health profile.
No physician sign-off, no order. That's the standard we hold to.
Request Consultation for GHK-Cu →Frequently Asked Questions
Yes. GHK-Cu has an established topical application literature (cosmetic and wound-healing research), in addition to systemic injection studies. The research-grade lyophilized compound can be reconstituted for either route. Your physician will specify the appropriate administration route.
The color comes from the copper(II) chelate in the molecule. This is expected and does not indicate contamination or degradation. A colorless solution after reconstitution would suggest loss of the copper complex.
Lyophilized peptide powder: store at −20 °C for long-term (up to 24 months) or at 4 °C for up to 6 months. Once reconstituted: refrigerate at 2–8 °C, use within the timeframe specified on your product (typically 14–30 days). Avoid repeated freeze-thaw cycles.
Our lyophilized peptides carry a 24-month expiry from manufacture date as printed on the batch label. Each COA confirms the exact lot date and expiry. Once reconstituted, shelf life drops significantly — see the reconstitution notes for your specific compound.
SourcePeptideCo operates through a licensed physician network. Peptide research compounds can interact with medications, contraindicate with certain conditions, and require clinical judgment for correct dosing. We don't sell without physician oversight — not as a formality, but because the oversight is part of the value.
A Certificate of Analysis (COA) documents the test results for a specific production batch. It certifies identity (the peptide is what we say it is), purity (by HPLC-UV), molecular mass (by LC-MS), endotoxin levels, and sterility. Every batch is tested by an independent ISO 17025-accredited laboratory.
