GHK-Cu calculator

GHK-Cu math uses the listed vial sizes on this card and the liquid you type. Concentration in mcg per mL is vial milligrams times 1000, divided by milliliters. A U-100 syringe has 100 marks per milliliter, so each unit is that concentration divided by 100. Example numbers so you can see the math: a 100 mg listing plus 2 mL of liquid. Change any number and the units change. Try the numbers. A research-market vial is not the same material used in a trial.

These are example numbers so you can see the math. Try yours. Change them to match the vial in your hand.

0.5U-100 units · 0.005 mL

500 mcg per unit · 50000 mcg/mL

That draw is under 5 units, so the barrel is easy to misread. Add more liquid or measure a larger mass if you want a bigger mark. The page does not tell you to take more.

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

FDA product approval

not established. No US therapeutic product approval is established by this curated source set; other countries and products may differ.

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.

Risks and mix-ups already on the record

  • Safety is incomplete; absence of reports does not establish safety.
  • Unknown or incomplete for research formulations; this is not a clearance for use.
  • Unknown or incomplete; do not infer compatibility with medications or other substances.

People using PepBear often log: Existing clinician-directed records, symptoms and dated health measurements. Record missing data; trends do not demonstrate causation.

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.

How many units is a listed GHK-Cu vial after you add water?

Units = (amount in mcg ÷ (vial mg × 1000 ÷ water mL)) × 100 on a U-100 syringe. Enter the three numbers. The chart shows the same math for each listed vial size and 1, 2 or 3 mL of liquid.

Why flag amounts under 5 units?

A U-100 barrel is easy to misread below about 5 marks. That is a measuring warning. The page does not tell you to take more.
