Key features: Copper coordination at the histidine imidazole the histidine ring nitrogen is the primary copper-binding site Additional copper coordination via amine groups the lysine side chain and N-terminal amine participate in the copper binding pocket Square-planar copper geometry the copper(II) ion sits in a defined geometric configuration that determines activity Naturally occurring same molecular structure as the GHK-Cu found in human plasma, just synthesized for research-grade purity The copper coordination is what gives GHK-Cu most of its activity research has documented different activity profiles for GHK alone versus GHK-Cu
For body recomposition, the combination of a GH secretagogue with AOD 9604, a fragment of human growth hormone that drives lipolysis through beta-3 adrenergic receptors without affecting muscle anabolism, is worth considering for patients whose primary concern is concurrent fat loss and muscle preservation
Understanding their subtle differences is key for any researcher designing a study
