| GHK-Cu | Tesamorelin / CJC-1295 / Ipamorelin | |
|---|---|---|
| What it is | A naturally occurring copper-binding tripeptide with a long history in topical skincare research. Injected use is not what the research studied. | Three growth hormone secretagogues in one vial, commonly 6:3:3. Two of the three do the same job, which is the thing worth knowing before buying it. |
| EvidenceHow much human evidence exists, not how well it works. | Preclinical | Preclinical |
| Regulatory statusReviewed 2026-08-12 | Permitted as a topical cosmetic ingredient in the United States and widely sold as such. Not approved as an injectable medicine, and injectable material is a research chemical with no manufacturing standard behind it. | The mixture is not approved anywhere. Tesamorelin alone is FDA-approved for HIV-associated lipodystrophy, at a dose and for a purpose that has nothing to do with this blend. |

| Storage once mixed | Refrigerated at 2–8 °C. The solution is characteristically blue; that colour is expected and is not a fault. | Refrigerated at 2–8 °C and used within about 30 days. A blend cannot be split. A contaminated vial takes every component with it. |

This page is educational. It describes what published research reports, not what you should do. Peptides discussed here are largely not approved for human use, and nothing on BioAlmanac is medical advice. Nothing here ranks these two against each other. A table can show that one has more human evidence behind it or costs less per milligram; neither of those is a recommendation, and the right comparison for any person is one their doctor makes with them.
