What are cosmetic peptides?

Cosmetic peptides are studied for their effects on skin, hair and pigment. GHK-Cu is the classic, a copper complex found naturally in human plasma and researched since 1973 for collagen and wound models. AHK-Cu is its cousin, studied mostly for hair follicles.

SNAP-8 is a longer version of Argireline, the peptide that made this field popular in skincare, and it’s studied for expression lines. Melanotan 2 acts on the melanocortin receptor that controls pigment. The GLOW blend and Smooth lotion combine several of these in one product.

How to choose cosmetic peptides

For skin and collagen research, GHK-Cu is the obvious starting point, as a vial, as capsules or inside the GLOW blend. For hair follicle work, choose AHK-Cu. For topical application, the Smooth lotion combines GHK-Cu, SNAP-8 and KPV.

Pigment research uses Melanotan 2, available as a vial and as a nasal spray. The Calabasas bundle groups the main skin and copper peptides at about 15% off.

Formats and prices at a glance

This range has 8 products: four lyophilized vials, one blend, one nasal spray, one capsule bottle and one lotion. Prices run from $34.99 to $169.99. Every product page lists the exact amount, the format and the SKU, so you can compare like for like before you order.

Quality, testing and storage

Most of our vials carry a QR code on the label that opens the certificate of analysis for that exact batch. Check the lot number on the COA against the vial before you open it, and keep a copy with your notes.

Store lyophilized vials in the fridge, or the freezer for long periods, and let them reach room temperature before opening. Sprays go in the fridge once opened. Capsules and lotions keep on a cool, dry shelf.

Copper peptides explained

GHK-Cu and AHK-Cu both bind a copper ion tightly. The peptide acts as a carrier, delivering copper to cells in a form they can use, and the copper is what gives the powder its blue color. Copper peptides are among the most studied compounds in skin research. AHK-Cu was developed from the same idea, with one amino acid changed, and it shifts the focus from skin to hair follicles. Both are sold here as 100mg vials.

Cosmetic peptides FAQ

What’s the difference between GHK-Cu and AHK-Cu?

One amino acid. GHK-Cu is mostly studied for skin, AHK-Cu for hair follicles.

Do you sell topical cosmetic peptides?

Yes. The Smooth lotion contains GHK-Cu, SNAP-8 and KPV.

Why is GHK-Cu powder blue?

Because of the copper. It’s normal.

Are cosmetic peptides for human use?

No. They’re sold for laboratory research only.
