### On this page

GHK-Cu 50 mg versus 100 mg: compare the exact material and labelled amount before comparing a quote. EPS is open for research and catalogue browsing; ordering and shipping have not opened, so this page does not present a live offer. Final EUR prices, shipping charges and tax treatment remain unconfirmed.

## EPS catalogue formats

Listing | Labelled amount | Price and report status

[GHK-Cu](https://europeanpeptideshop.com/shop/ghk-cu-50mg/) | 50 mg | Ordering closed; see the product page for its report status

[GHK-Cu](https://europeanpeptideshop.com/shop/ghk-cu-100mg/) | 100 mg | Ordering closed; see the product page for its report status

The 100mg GHK-Cu vial has twice the labelled amount of the 50mg vial. Whether it has the lower cost per mg depends on the current prices. Compare the listed formats, then request final pricing and matching documentation. A larger label does not mean higher purity.

## What do the 50mg and 100mg vials cost?

Price per labelled milligram means the vial price divided by the amount on its label. It is not a measured batch-content result. Shipping, quantity pricing and coupons can change the checkout total. Check availability and dispatch information separately from the price.

## Is one 100mg vial better value than two 50mg vials?

Compare one 100mg vial with the actual checkout price of two 50mg vials. Include quantity pricing and shipping. Separate containers may be useful when the laboratory work requires independent preparations; a lower price per mg is only one part of that choice.

Do not assume that a report for a 50mg lot also covers the 100mg lot. Use the report linked to each listing and check the sampled quantity. [how to check a lab report](https://europeanpeptideshop.com/blog/how-to-read-peptide-coa/) explains how to match those details.

## Does 100mg mean twice the purity?

No. Milligrams describe the labelled amount; purity is a separate test result. Neither number by itself establishes suitability for personal use. To compare batches, read the applicable reports rather than borrowing a percentage from another size.

## Are GHK, GHK-Cu and copper-peptide skincare comparable?

They can describe different materials. GHK is a peptide; GHK-Cu is its copper complex. A finished cosmetic contains a formulation, and a percentage on that product may refer to an ingredient solution rather than the same weighed material as a research vial. The [GHK-Cu guide](https://europeanpeptideshop.com/blog/ghk-cu-research/) explains the distinction.

## How do GLOW and KLOW fit into the comparison?

These measurements describe the submitted samples. They do not establish the contents of every vial, the lot currently dispatched or a nominal blend recipe. Price per labelled mg of a blend is a price per mg of total blend, not per mg of this component.

Those blends include GHK-Cu with other peptides. The total blend amount is not the amount of GHK-Cu alone. Check each ingredient and its stated amount before comparing a mixed vial with standalone GHK-Cu. See [GLOW vs KLOW](https://europeanpeptideshop.com/blog/glow-vs-klow-peptide-blends/).

## Before comparing an order total

Keep the supplier quote, labelled quantity, applicable taxes and shipping charge together. A sample checkout subtotal is not a confirmed delivered price. The [shipping page](https://europeanpeptideshop.com/shipping/) will carry the final arrangements when the store launches. A lower unit price cannot replace a matching specification or batch report.

## EPS documentation

Use the [research catalogue](https://europeanpeptideshop.com/shop/) to check the exact name, labelled amount and format. The [COA library](https://europeanpeptideshop.com/coa/) publishes the original Janoshik reports selected for EPS, retaining the original report client name and any missing batch fields. Literature findings and another supplier's analytical results are not evidence about an EPS batch.
