Documented mechanisms of action Preclinical studies (mostly Russian, to be reproduced in international protocols) report several mechanistic targets: BDNF increase (Brain-Derived Neurotrophic Factor) in the hippocampus and frontal cortex, measured by ELISA and Western blot 24-72 h post-administration Monoaminergic system modulation : cortical dopamine increase, serotonergic modulation Activation of the melanocortin pathway via MC4R receptors (residue shared with ACTH) Anti-oxidant and anti-apoptotic effect in cerebral ischaemia models (MCAO, middle cerebral artery occlusion) Experimental paradigms The most reported rodent models are the Morris water maze (spatial memory), novel object recognition (recognition memory), passive avoidance (aversive learning)
Gene-profiling work reported that GHK modulates the expression of a substantial fraction of human genes upregulating antioxidant, DNA-repair, and tissue-remodeling pathways while downregulating inflammatory and pro-fibrotic genes producing transcriptional profiles characteristic of less-aged cells in vitro 1
Repressing the storage of additional glycogen and fat deposits
Before the peptide can be used in experiments, the powder must be reconstituted with a sterile solvent , creating a liquid solution with a known concentration
