How many vials are in a kit?

Ten. A kit is 10 vials of the same product and strength.

What is the minimum order?

One kit per product and strength. Different products and strengths can go in one order, each from one kit.

In writing, by the kit. Prices are tiered by the number of kits of each product and strength, and the quote states the unit price, shipping and lead time.

Payment is not taken on this website. After you accept the written quote, sales arrange payment with you by chat or email.

What does the batch COA report?

HPLC purity, MS identity, bacterial endotoxin and fill, for the batch whose number it carries. Each batch of a stocked product has its own COA.

Its copper(II) ion absorbs light in a broad band near 606 nm, in the orange-red part of the spectrum, so the material looks blue. A white powder sold as GHK-Cu has no bound copper.

Copper peptides & blends · by the kit

Copper peptides and copper blends in lyophilized vials, sold by the kit.

GHK-Cu and AHK-Cu, and three blends built on GHK-Cu — GLOW, KLOW and a 50 mg GHK-Cu, TB-500 and BPC-157 vial — as lyophilized powder in sealed vials: 10 vials of one strength per kit, from one kit, with a COA for each batch. We supply peptide distributors, clinics and med spas, individual researchers and research laboratories.

Spray & capsules · US stock

GHK-Cu in a spray bottle, and capsule bottles too — stocked in the US

Besides the blue lyophilized powder, GHK-Cu 100 mg is sold in nasal spray form; the spray comes in 10 or 20 mL bottles. Separately, we keep capsule bottles of selected compounds — ask our sales team for that list and a quote. Both ship within the US, from the stock we hold there.

Check a batch

Three checks for any GHK-Cu batch.

Whoever you buy from. Each check uses a number you can look up: PubChem records and published spectra.

01
Colour
GHK-Cu is blue: the copper(II) bound in the peptide absorbs near 606 nm. A white powder sold as GHK-Cu has no bound copper.
02
CAS and molecular weight for the form
89030-95-5 is the copper complex; 49557-75-7 is GHK without copper. 401.91 g/mol is the neutral 1:1 complex, 742.3 g/mol the 2:1 form.
03
The copper lines of the COA
HPLC purity measures the peptide only. Copper content and peptide content give the Cu²⁺ : peptide ratio — about 1.0 for a 1:1 batch.

Batch data

A COA for each batch of every copper product.

The COA carries the number of the batch it covers. Ask for the COA of the batch you would receive; sales send it with the quote.

On every batch COA

Batch COA — issued for the batch, with its batch number
HPLC purity — reversed-phase HPLC result against the purity specification
MS identity — mass spectrometry confirming the peptide
Endotoxin — bacterial endotoxin result for the batch
Fill — measured amount per vial against the labelled amount
