Where to buy GHK-Cu
Vendors we have vetted on testing, certificates of analysis, and shipping. These are plain references, not affiliate links — see the disclosure below.
| Vendor | 3rd-party tested | COA | Ships to | Notes |
|---|---|---|---|---|
| Vendor B (placeholder) | Yes (Colorado Peptide Lab) | Yes | US, CA | Illustrative entry. Third-party tested with per-batch certificates of analysis. Replace with a real vetted vendor post-legal-review. |
| Vendor C (placeholder) | No | No | US | Illustrative entry kept deliberately weak (no third-party testing, no COA) to exercise the "caution" rendering path in the template. |
