Insufficient human clinical data Most research on AOD-9604 has been conducted in animals or short-term human trials, making it difficult to determine its full long-term effects

Topical / Transdermal: Highly documented in dermatological research, as the low-molecular-weight GHK-Cu complex effectively penetrates the stratum corneum to stimulate local collagen, decorin, and glycosaminoglycan synthesis in the dermal matrix.[2] Study Duration GHK-Cu research generally follows both sub-acute and longitudinal timelines depending on the tissue remodeling goals: Wound Healing & Acute Repair: 2 to 4 weeks is the standard timeline for observing accelerated angiogenesis, enhanced blood vessel formation, and macroscopic wound closure in severe injury models.[3] Longitudinal Skin / Anti-aging Models: 8 to 12 weeks for observing sustained upregulation of structural proteins and the restoration of replicative vitality in aged or radiation-damaged fibroblasts.[1] Evidence Limitations While decades of in vitro and animal models demonstrate GHK-Cus profound ability to accelerate tissue remodeling, attract immune cells, and modulate inflammatory pathways, it is not approved by the FDA as an injectable therapeutic for wound healing, anti-aging, or systemic inflammation in humans
