High-quality GHK-CU AHK-Cu | Cosmetic Peptides | 99% Purity | 50mg 100mg Vial | Lyophilized Powder

Chemical Properties: Ahk cu is a hexapeptide-copper complex. Its core structure consists of an acetylated hexapeptide sequence (containing multiple histidine residues) forming a stable coordination complex with Cu²⁺, with the imidazole ring of histidine serving as the central coordination site. Chemically stable, it resists dissociation within a pH range of 5.0–7.5 and exhibits significantly superior resistance to peptidase hydrolysis compared to free peptides. It demonstrates excellent compatibility with common cosmetic ingredients such as vitamin C, ceramides, and hyaluronic acid, carries no risk of oxidative discoloration, and its complex structure protects copper ions from reduction.

     Physical Properties: Ahk cu appears as a white to light blue-gray crystalline powder at room temperature, odorless and tasteless. It exhibits excellent water solubility (solubility ≥100 mg/mL), dissolving rapidly in aqueous systems like pure water and physiological saline. It is slightly soluble in ethanol and propylene glycol, but insoluble in non-polar solvents such as ether and petroleum ether. Store at 2-8°C in a dry, sealed container protected from light. Avoid exposure to high temperatures (>40°C) and strong reducing agents. Cosmetic-grade product purity ≥98% (HPLC detection), copper ion complexation rate ≥95%.

     Source and Preparation: Ahk Cu has no natural occurrence and is synthesized via a two-step process: “solid-phase synthesis + complexation purification.” High-purity L-amino acids are first synthesized into acetylhexapeptide-1, which undergoes complexation with copper sulfate/chloride under neutral conditions. Free peptides and uncomplexed copper ions are subsequently removed via dialysis and column chromatography purification, ensuring structural uniformity and biological activity of the final product.

AHK-Cu appears in blue state, featuring repairing, hair regrowth, anti-aging, antioxidant and whitening effects. It is widely applied in hair growth products and daily cosmetics.

1. How to make an order?
Send me message and let me know what you need with quantity , then i will calculate to you.

2. What's the lead time and shipping ways?
We will delivery to the package by USPS, FEDEX, DHL paket and UPS express to you after receive your payment, it would take around 12-15 days to your address.

3. How do i keep the peptides when i receive it ?
Peptides in the form of lyophilized powder can be transported at room temperature by vacuum packaging, while polypeptides in the dissolved state need to be refrigerated at 2°C - 8°C. For long-term storage, peptides should be stored in the form of lyophilized powder store at -20°C or -80°C in a sealed container with desiccant, which can avoid the degradation of peptides to the greatest extent.

4. What's the payment methods ?
We could accept pay through usdt,bank transfer.
