GHK-Cu
GHK-Cu is a three-amino-acid peptide that binds copper. Papers look at wound-healing gene activity and cosmetic skin use. Injectable research vials and creams are different products. Listed seller masses here include 100 mg and 200 mg labels. Those are listing sizes for the chart. Cream stays cream.

What is GHK-Cu?
The library also has GHK without copper and several LVLUP-branded GHK products on separate cards. Copper content changes what a paper can support. Salt form does too. Cream versus vial changes it again. A cream result does not move to a vial.
Copper-binding tripeptide; findings for one formulation cannot establish benefit or safety for another.
Regulatory status, dated 2026-10-09
Compounding
not established. Compounded products do not carry FDA product approval; legal eligibility is not established here.
Research
investigational. Human injectable safety and therapeutic evidence remain insufficient.
Sport
unknown. Not individually verified; consult the current sport rules. Absence of a listing is not permission.
What the cited papers actually measured
Pickart’s reviews (including PMID 18644225 and later updates such as 29972712) summarize gene-expression and wound models. Those papers are mostly lab and observational cosmetic work. They do not approve an injectable wellness product. They do not grade seller purity. This catalog does not record a US drug approval. A cream study that tracked skin appearance does not move its measurements onto a 100 mg research vial sitting in a fridge.
We mark the cited papers as D. That is our label for how strong those papers are. It does not say the compound works.
How long it lasts, how you store it, listed sizes
The catalog does not record a single hour value. No verified formulation-specific human estimate in this source set; no guessed value is supplied.
100 mg and 200 mg listings look large next to 5–10 mg healing peptides. Treat them as labeled masses for math. They are not a hint that more is better. Follow the product label for light and temperature. Copper solutions can stain. That is a handling fact. Wipe the bench. If a 200 mg listing sits next to a 5 mg healing-peptide row, that gap is a seller title, not a hint that the larger number is the one a paper used.
U-100 math for listed GHK-Cu sizes. Each cell is micrograms per syringe mark if you add that much liquid. The table does the same math as the calculator. It does not pick an amount for you.
| Listed vial | 1 mL liquid | 2 mL liquid | 3 mL liquid |
|---|---|---|---|
| 100 mg | 1000 | 500 | 333.3 |
| 200 mg | 2000 | 1000 | 666.7 |

Questions people ask
Is GHK-Cu an FDA-approved drug?
This source set shows no US drug approval. Cosmetic uses, if any, sit in a different bucket than a drug approval.
Why is the units chart using 100 mg?
That mass appears on seller listings tied to this catalog id. Type a different mass if your vial says something else.
