How to read this board
Direct official prices only. No affiliate commission is currently attached to these links. No copied reviews, hidden score, or universal best claim. Availability and prices can change after the checked date.
Normalized board
Price per 30 mL makes unlike bottle sizes legible.
A low normalized price does not prove better performance, stability, tolerability, or value for a particular person. It answers one narrow question well: how much does the current formula cost at a common volume?

Evidence ledger
What each product page can actually support.
Brand tests can help describe one finished formula. They cannot prove that the formula beats every other serum or that an ingredient result transfers to every product.
Squalane + Copper Peptide Rapid Plumping Serum
The official page reports brand product studies involving 31 women. Those results apply to this finished formula and are not a comparison with the other products here.
Inspect official evidence and label ↗Copper Peptide Pro Firming Serum
The official page reports brand product studies. They are formula-specific and are not head-to-head evidence.
Inspect official evidence and label ↗Liquid Peptides
The official page reports an independent consumer study of 60 participants over eight weeks. It is product-specific consumer evidence, not a head-to-head clinical trial.
Inspect official evidence and label ↗Copper Amino Isolate Serum 3 1:1
The official ingredient and product page supports the label description. It does not establish superiority over other finished formulas.

Small board, strict comparison.
- Use the official US product page, not a marketplace copy.
- Record the displayed direct price, bottle volume, and availability.
- Calculate price per 30 mL as price divided by volume, multiplied by 30.
- Record copper-peptide language only when visible on the official page or ingredient list.
- Describe product studies as brand or product-specific and never as head-to-head proof.
Tax, discounts, subscriptions, shipping, and bundles are excluded unless the official displayed price requires them. Check the seller page before purchase.

Price is one column. The formula is the decision.
Use the skincare guide to interpret ingredient families and cosmetic claims. Use the GHK-Cu category guide if a page crosses into research, compounding, injection, or clinical-trial language.
