Not listed or not clear
The amount shown is what the store lists. It is not advice on how much to use. We show price per milligram (mg) only when the whole pack amount is clear. IU is a different unit. We do not turn IU into mg.
Pack details not clear
This is the store’s price before shipping, tax or codes with extra rules. We do not check if a product is genuine, safe or approved for sale.
THE PRODUCT BEHIND THE PRICE
What this listing tells you.
Read the whole pack.
GHK-Cu is a listing from PeptideStacks. The saved ingredient label is GHK-Cu. The product form was not clear in the source.
We cannot state a clear total in mg for this pack, so a price per mg would be a guess. This often happens with blends, units such as IU, or a label that does not say how many items the price covers. A pack amount is not an amount to use.
Read the price in time.
There are 2 saved checks shown in this page’s history starting October 20, 2026 and running through October 22, 2026. A saved check records what the seller showed at that time.
A seller’s crossed-out price and a price drop we observed are different facts. The history below shows our checks. Delivery, tax, account-only prices and codes may change what you pay at the store.
Use the side-by-side pack table to check the same ingredient, form, amount and number of items. A cheaper price across different packs is not a like-for-like result.
THE SCIENCE BEHIND THE NAME
Get to know the named ingredients.
GHK-Cu
A small peptide joined to copper. Researchers ask how it affects skin and tissue signals. GHK-Cu is a copper-bound complex of the three-amino-acid peptide glycyl-histidyl-lysine. Exact salt, copper ratio and finished-form identity need the maker’s documents.
A small randomized study of skin care after laser treatment had 13 completers. Objective redness and wrinkle measures did not differ significantly between groups, though satisfaction was higher with GHK-Cu. Another trial studied a specific topical gel with diabetic-ulcer care. The results apply to the specific topical formulations and clinical settings studied.
Compare the amounts and prices listed by sellers. A milligram (mg) is a small unit of weight. Price per mg means the pack price divided by its total mg. The bars show prices checked within 72 hours in CAD only. A shorter bar means a lower price per mg. We leave the total blank if the seller has not given enough facts.
