Copper Tripeptide-3
Copper Tripeptide-3 • 99%+ Purity • HPLC Verified
AHK-Cu (Alanine-Histidine-Lysine Copper) is a next-generation synthetic copper peptide engineered specifically for targeted hair follicle activation and advanced skin regeneration. Unlike naturally occurring GHK-Cu, AHK-Cu is designed with a focused mechanism of action that makes it the gold standard for scalp and hair care formulations.
This powerful tripeptide works at the cellular level by binding to copper ions, enabling critical biological processes including collagen synthesis, wound healing, and enzymatic activity. The histidine residue provides a key coordination site for copper binding, creating a stable metal-peptide complex that influences cellular signaling and tissue repair pathways.
Our AHK-Cu powder is supplied at 99%+ purity, verified by HPLC analysis. Each batch is carefully tested to ensure optimal potency and effectiveness for your cosmetic formulations.
Stimulates dermal papilla cells and promotes the anagen (growth) phase of hair follicles. Research shows AHK-Cu can significantly extend the hair growth cycle.
Helps protect hair follicles from DHT-related damage and miniaturization — one of the primary causes of androgenetic alopecia (pattern hair loss).
Boosts collagen and elastin synthesis, improving skin texture, tone, and flexibility while visibly reducing wrinkles and fine lines.
Increases VEGF production, enhancing blood flow to follicles and ensuring they receive vital oxygen and nutrients.

Dissolve the desired amount of AHK-Cu powder in distilled water. For a 0.01% solution, add approximately 0.1g of AHK-Cu to 1 liter of water. The powder dissolves easily at room temperature.
Ensure your final formulation has a pH between 5.5 and 7.0. AHK-Cu works best within this range. Avoid using with acidic ingredients like vitamin C, AHAs, or citric acid.
Add the AHK-Cu solution to serums, creams, shampoos, conditioners, or scalp treatments. The typical use level is 0.001% to 0.01% of total formulation weight.
Store your finished product in a cool, dark place. For best results, use amber or opaque containers to protect from light degradation.
