GHK-CU CU50 GHK-CU50

Standards for Appearance and Characteristics：The product appears as a pale blue or bluish-purple, loose, freeze-dried solid—distinct from the vast majority of white peptides. It is normal for the solid to crumble into loose powder due to vibration during transport; its activity remains unaffected. The powder is dry and fluffy, resistant to moisture absorption or sticking to the vial walls, and odorless; there is no condensation or powder leakage inside the vial.

Mechanism of Action and Key Benefits：Promotes collagen and elastin synthesis for anti-aging and firming effects
Stimulates fibroblast activity, boosting the production of Type I and III collagen and hyaluronic acid; addresses soft tissue laxity, fine lines, and rough texture; repairs photo-aging damage while enhancing skin firmness and radiance.
Repairs soft tissue and accelerates recovery from injury
Regulates the balance of matrix metalloproteinases (MMPs) and accelerates the repair of micro-injuries in superficial soft tissues and fascia; reduces post-traumatic edema and inflammatory responses.
Potent antioxidant action and reduction of chronic inflammation
Scavenges free radicals, inhibits the NF-κB pathway, and downregulates various pro-inflammatory factors; alleviates chronic low-grade inflammation and redness/sensitivity, while reducing post-exercise tissue soreness and inflammation.
Optimizes microcirculation and enhances nutrient delivery
Gently promotes local microcirculation, increases tissue oxygen supply, and facilitates the elimination of metabolic waste; improves slow tissue recovery caused by poor circulation.
Balances skin pigmentation and fades marks
Moderately inhibits tyrosinase activity; improves the appearance of acne marks and superficial pigmentation, resulting in a more even skin tone.

Storage Guidelines
Unopened Lyophilized Vials
Long-term storage: Store sealed and protected from light at -20°C; shelf life is 12–24 months.
Short-term storage (to be used within 3 months): Store refrigerated at 2–8°C, protected from light. Avoid high temperatures, repeated freeze-thaw cycles, and direct sunlight.
Reconstituted Solution (with BAC)
Store refrigerated at 2–8°C, protected from light, throughout the usage period. Strict 28-day expiration limit; discard all remaining solution after this period. Do not freeze the solution; freezing causes irreversible damage to the chelated structure, rendering it permanently ineffective.
