GHK-Cu: the copper peptide.
GHK is a short peptide made from glycine, histidine, and lysine. GHK-Cu refers to its copper complex. It is a specific ingredient identity, rather than a general name for every peptide used in skincare.
The GHK-Cu gel patch sample places this ingredient story at the center of a targeted care concept. The finished formulation and its supporting documentation will define the product, including the final ingredient list and any substantiated cosmetic claims.

PDRN stands for polydeoxyribonucleotide, a material composed of DNA fragments. It is not a peptide. The distinction matters when reading product names and comparing scientific background.
Our PDRN Microneedle Patches sample introduces an eye-contour care concept. The product name alone does not confirm the complete formulation, ingredient source, or concentration. Those details belong in the final product documentation.

The label is the starting point.
A product story may highlight one ingredient, but a complete formula usually tells a more detailed story. The ingredients that receive the largest type on the front of a pouch are not a substitute for reading the full list.
The supplied PDRN back label also mentions GHK-Cu. We are treating that as sample wording requiring confirmation, rather than evidence that the final PDRN product contains a particular peptide or combination. Precise naming is part of making the collection easier to understand.
An ingredient is not a promise.
Ingredient research can explain why a material attracts interest. Product evidence is what supports a claim about a specific finished product. The route of use, formulation, test conditions, and measured outcomes all belong in that conversation.
We avoid presenting PDRN and GHK-Cu as equivalent, and we do not infer the performance of our samples from another product or a different setting. Our science page explains how to read that distinction.

As launch information becomes available, look for the full ingredient list, the intended application area, product-specific directions, and evidence that matches the finished formula. If any detail is missing, it is reasonable to ask before deciding.
Ingredient sourcing and suitability questions deserve product-specific answers. Contact our product team with the exact product name, and include batch information if you are asking about a sample.
