Product Description: Module D is one of five products within PHP’s Modular Peptide System, a modular framework of peptide formulations designed for research evaluation. Researchers may evaluate individual modules independently or as part of three structured configurations: Phase 1, Phase 2, or the Complete Configuration. Module D is a peptide formulation centered on AHK-Cu, a copper-coordinated peptide complex representing a distinct chemistry class within the modular framework. Unlike the free peptides utilized elsewhere in the system, AHK-Cu exists as a coordinated metal complex, introducing analytical variables specific to copper coordination chemistry. Composition is independently verified through ISO/IEC 17025-accredited analytical testing using HPLC-UV-MS methodology. Batch-specific Certificates of Analysis are available through the COA-Topicals library. Module D is the only product within the framework in which the peptide exists as a coordinated metal complex rather than a free peptide. Research Framework:

• Distinct copper-coordinated peptide chemistry class
• Single-peptide composition with supporting formulation architecture
• Elevated-concentration advanced module
• Compatible with Phase 2 and Complete Configuration
• May be evaluated independently or alongside Module B
• Includes the system’s only coordinated metal-peptide complex

Formulation Characteristics:

• AHK-Cu serves as the primary peptide component at 0.10%
• Tocopherol (Vitamin E) incorporated as part of the formulation’s oxidation-management architecture
• Buffered serum-emulsion matrix engineered for copper-peptide stability
• Chelation system incorporated to support coordination-complex integrity
• Elevated pH range relative to other modules to accommodate copper-complex stability requirements
• Airless packaging minimizes oxygen exposure and supports compositional integrity
• UV-protective packaging is particularly important for copper-coordinated peptide systems

Comparative Position Within The System: Within the modular framework, Module D functions as the advanced composition and represents a distinct chemistry class relative to the other products in the system. It is analytically paired with Module B, as both products utilize elevated-concentration, single-peptide-dominant architectures while representing different formulation and chemistry frameworks. AHK-Cu also appears at a lower concentration (0.02%) within Module E, enabling comparative evaluation of the same compound at different analytical levels across the system. Copper-Peptide Selection Rationale: PHP’s formulator selected AHK-Cu as the copper-peptide component of Module D based upon formulation-engineering considerations related to compositional stability. AHK-Cu is the copper coordination complex of N-acetyl-alanyl-histidyl-lysine, an N-terminus-acetylated peptide structure. The acetylation modifies copper coordination behavior, contributing to stable formulation characteristics across the pH ranges typically encountered in aqueous peptide systems and supporting long-term compositional integrity throughout the documented shelf life of the product. This represents a formulation-design decision regarding stability and composition rather than a comparative statement regarding biological or topical activity. Product Specifications:
