GHK-CU vs AHK-CU
Two 100mg copper-peptide Skin listings. Catalog shopping comparison, not a wound-care protocol.
These overviews are product information for laboratory and research use. They are not medical advice, not a protocol, and not a claim that any listing diagnoses, treats, cures, or prevents disease.
Two copper peptides, two 100mg listings
GHK-CU is glycyl-L-histidyl-L-lysine bound to copper, listed as a 100mg lyophilized vial. AHK-CU is alanine-histidine-lysine bound to copper, also a 100mg lyophilized vial. Both sit in Skin & appearance. They are separate SKUs. This shop does not treat AHK-CU as a size of GHK-CU, or GHK-CU as a larger AHK-CU.
Single-compound notes: What is GHK-Cu? and What is AHK-Cu?. This page is only a catalog comparison. Appearance-focused product information — not a wound-care protocol.
How the catalog stories differ
The GHK-CU page frames copper-peptide research angles people usually open that listing for: collagen, skin firmness, hair appearance, and scar repair. The AHK-CU page frames a different copper peptide around collagen, hair appearance, and skin repair, including scalp and follicle appearance. Those lines explain why two copper-peptide cards sit in the same group. They are not diagnoses, not clinic instructions, and not a claim that scars, hair, or skin disease will change on a schedule.
The names on the vials are the first catalog difference shoppers notice: GHK vs AHK. Same listed size (100mg). Different sequence. Buying one is not buying the other.
When a shopper might open one vs the other
Someone browsing this catalog might open GHK-CU when they want the glycyl-histidyl-lysine copper listing. They might open AHK-CU when they want the alanine-histidine-lysine copper listing. Those are shop reasons — compound name on the card — not medical criteria.
Nearby skin-group listings include the blends KLOW (GHK-Cu, KPV, BPC-157, TB-500) and GLOW (BPC-157, GHK-Cu, TB-500). See KLOW vs GLOW. Those blends are their own SKUs. This comparison does not tell you to combine a copper-peptide vial with either blend.
Testing, COA, and research-use notes
Both listings are Janoshik tested. We do not print a purity percentage or a lot number on the product page. How research peptides are supplied and how to read a COA explain what we will and will not publish. Storage stays high-level. We do not provide mixing, reconstitution, or dosing instructions.
FAQ, shipping, and policies cover checkout and research use. This shop ships US-wide to United States addresses. Inquire about GHK-CU or AHK-CU. More notes: research overviews.
