GHK-Cu Price: Cost per mg at Every Vendor We Review

GHK-Cu looks cheap next to every other peptide on the tracker, and it is: vials hold 50 or 100 mg, not 5 or 10, so the price per milligram is the smallest on the board and a vial price in the tens of dollars is normal. That also makes it easy to misread. A 100 mg vial for the price of a 10 mg vial of something else is not a bargain, it is a different amount of a different, much lighter, molecule. This page prices the injectable research vial from each vendor's own store data every morning and explains how to compare it fairly.

What You Are Paying For

GHK-Cu is the copper complex of glycyl-L-histidyl-L-lysine, a three amino acid peptide that is present in human blood and falls with age. It is better known as a skincare and hair ingredient than as an injectable: copper peptide serums are sold everywhere, and the topical GHK-Cu page and copper peptides for hair cover that side. The GHK-Cu guide covers the injectable research literature, which is smaller and mostly preclinical.

A tripeptide is the cheapest kind of peptide to make, so the cost floor is very low and the difference between vendors is mostly margin, testing and how much copper is actually bound. That last point is specific to this compound. Plain GHK without copper is a different product, and a vial can be short of copper while passing a purity test on the peptide alone. A good certificate reports the copper content or at least identifies the complex, not just the tripeptide.

How to Read a GHK-Cu Price

Vendors sell GHK-Cu in 50 mg and 100 mg vials, so the vial price alone tells you little. Divide the price by the milligrams in the vial and every listing collapses into one figure you can compare: the price per mg in the tables above. Because the numbers are cents rather than dollars, the table shows them to the cent and the size table shows the lowest price at each vial size. Four things move the figure.

• Vial size. The 100 mg vial is usually cheaper per mg than the 50 mg one, but only if you will use it. A mixed GHK-Cu solution keeps for weeks in a fridge, not months, and a large vial mixed at once can waste more than it saves. The storage guide covers the stability side.
• Colour and appearance. The copper complex is blue. A freeze-dried GHK-Cu powder and its solution are blue to blue-violet; a white or colourless powder sold as GHK-Cu is worth a question to the vendor.
• Where the vendor sits in the supply chain. Almost no Western research vendor synthesises anything. They buy bulk material from a small number of manufacturers, then fill, freeze-dry, label and ship, so two vendors at very different prices are often selling material from the same source.
• Testing. A vendor that pays for a third-party certificate on every batch carries a cost that a vendor publishing one old certificate does not. That is a reason to pay a little more, and a reason to check that the certificate is for your batch.

Listings that bundle GHK-Cu with other peptides (the "glow" and "klow" blends) are left out of the table, because a blend has no single price per mg to compare.

Injectable, Topical and Cosmetic: Three Different Purchases

Most of the GHK-Cu sold in the world is in creams, serums and microneedling products, and those are priced per bottle, not per milligram. A research vial is something else: a freeze-dried powder sold for laboratory use only. If you are comparing a 50 mg research vial with a $30 serum you are comparing different things, in concentration, purity standard and intended use, and the Bureau does not recommend using a research vial on skin or in the body. Nothing here is medical advice.

Inside the research-vial market the spread between vendors is wide in proportion, because the base cost is so low that every added cent of margin or testing shows up. That makes the certificate more informative than the price: two vendors at similar prices can differ by whether they publish a batch-specific test, and that is the column to check first.

How to Check a Vendor Before You Pay

The cheapest listing in the table is only cheap if the vial holds what the label says. Four checks take ten minutes.

• Match the certificate to your batch. A useful certificate of analysis names the lab, the batch or lot number, the date, an HPLC purity figure and a mass spectrometry identity check. A generic certificate with no batch number proves nothing about your vial, and for GHK-Cu it should say something about the copper. The peptide testing guide shows what a real one looks like.
• Type the address yourself. Popular vendor names attract look-alike domains, some of which take payment and ship nothing. The guide to buying peptides covers how to tell a real store from a copy.
• Pay by card on a first order. Crypto and bank transfer discounts are real, and so is the chargeback right they cost you. Take the discount once a vendor has delivered.
• Read the review. Every vendor in the table links to the Bureau's review or scorecard entry, which says what the vendor states, what the Bureau could verify and what it could not. The 2026 vendor scorecard ranks the ones we score, and the coupon page lists the codes we have seen work.

Doses are outside the scope of this page. How a research schedule is usually written is in the GHK-Cu injection dosage page, and the side effects page covers what was reported.

Frequently Asked Questions

What is the price of GHK-Cu today?

On 28 October 2026 the lowest in-stock price among the vendors the Bureau reviews was $0.35 per mg (Luv Aminos, 100 mg for $35.00), the median was $0.69 per mg and the highest was $1.30 per mg (Pantheon Peptides, 50 mg for $65.00). Prices are list prices for single vials before any code, read from each store's own data.

How much does GHK-Cu cost per mg?

Far less than most peptides, because vials hold 50 or 100 mg. The table above gives the price per mg at every vendor, refreshed every morning, to the cent, and the size table gives the lowest in-stock price for a 50 mg and a 100 mg vial. Prices are list prices before any code.

Is a 100 mg vial of GHK-Cu cheaper than a 50 mg vial?

Usually, per milligram. The size table shows the lowest in-stock price per mg at each size. A 100 mg vial only saves money if you use it before the mixed solution degrades, so a 50 mg vial can be the better buy for a short protocol.

Why is my GHK-Cu blue?

Because the copper complex is blue. A freeze-dried GHK-Cu powder and its solution are blue to blue-violet, and a white or colourless powder sold as GHK-Cu may be the peptide without copper. Ask the vendor what the certificate says about copper content.

Is the cheapest GHK-Cu listing the best buy?

Not on price alone. A price far below the rest of the market can mean a vendor clearing stock, a vial holding less than the label says, or a product without the copper. Check that the vendor publishes a batch-specific certificate with HPLC purity and mass spectrometry identity before treating a low price as a bargain.

How do I work out the cost of one dose?

Multiply the price per mg by the amount in milligrams; amounts are often written in micrograms, and 1,000 mcg is 1 mg. The Peptulator GHK-Cu calculator does the arithmetic and gives the syringe mark for a given vial and water volume; the dosage page covers how schedules are written.
