GHK-Cu is a naturally occurring tripeptide copper complex with diverse biological activities. It regulates copper ion metabolism to exert antioxidant, anti-inflammatory, and collagen – synthesis – promoting effects. Widely used in cosmetics, skincare, anti – aging products, and healthcare, GHK-Cu improves skin aging, promotes wound healing, and enhances skin elasticity. It also offers anti-inflammatory and antioxidant benefits, promotes hair health, regulates gene expression, and aids in treating certain diseases. As a multifunctional bioactive molecule, GHK-Cu shows great potential in delaying aging, boosting skin health, and improving tissue repair.
BAC Water (Bacteriostatic Water) is a sterile injectable water containing benzyl alcohol, which exhibits broad-spectrum antimicrobial activity. It is suitable for dissolving, diluting, or reconstituting lyophilized peptides, proteins, and bioactive molecules. Benzyl alcohol inhibits microbial growth, maintaining the sterile condition of multi-dose vials. It preserves peptide stability, prevents degradation, and extends the shelf life for multiple withdrawals. This water is low-ionic, pyrogen-free, and allergen-free, and is compatible with various synthetic peptides such as BPC-157, TB-500, and IGF-1 LR3. Compared to conventional sterile water, it supports repeated sampling, remains stable at room temperature, and reduces reliance on the cold chain.

Klow is a blend comprising TB4, BPC-157, KPV, and GHK-CU. TB4 modulates actin dynamics to promote cell migration, angiogenesis, and collagen synthesis, supporting connective tissue regeneration; BPC-157 upregulates relevant factor expression, enhances angiogenesis and fibroblast activity, repairs multiple tissues, and provides cellular protection; KPV suppresses pro-inflammatory factors, reduces inflammation, and promotes mucosal repair; GHK-Cu stimulates collagen production, regulates inflammation and antioxidant activity, and supports tissue repair. The four peptides complement each other: TB500 and BPC-157 provide migration-angiogenesis-matrix templating, KPV blocks inflammatory negative feedback, while GHK-Cu stabilizes collagen cross-linking and scavenges free radicals. This forms an “anti-inflammatory-migration-regeneration-remodeling” closed loop, enabling Klow to significantly accelerate repair, reduce scarring, and restore function in soft tissue injuries, postoperative healing, skin aging, and mucosal ulcers.
NAD+ (Nicotinamide Adenine Dinucleotide) is a critical molecule universally present in living organisms. It plays a key role in essential physiological processes such as cellular energy metabolism, DNA repair, and antioxidative stress, providing fundamental support for normal cellular function. By activating anti-aging factors, NAD+ promotes cell repair and regeneration, slows down the aging process, and demonstrates significant effects in enhancing immunity, improving metabolic health, protecting the cardiovascular system, and maintaining neural function. As a core molecule in anti-aging research, NAD+ not only sustains daily health but also offers new directions for delaying aging and preventing diseases.
