is ghk-cu a growth hormone Peptide Therapy Guide: GHK-Cu, CJC Unlocking the Secrets of GHK-Cu:

GHK-Cu may help support collagen and elastin, while NAD+ is linked to cellular repair and response to oxidative stress

Benefits May enhance focus, improve emotional resilience, reduce stress, promote mental clarity, and support overall brain health

When you take both together, they are activating the same physiological endpoint (GH secretion) through different receptor pathways

In neuronal senescence model studies, the active ingredient of the product can cross the blood-brain barrier (and act directly on neurons in vitro), increase NAD+ levels in nerve cells, protect mitochondrial function, reduce neuronal apoptosis, and promote the synthesis and release of neurotransmitters (such as dopamine and acetylcholine), thereby improving signal transduction in nerve cells
