GHK-Cu GHK-Cu is composed of a tripeptide (glycyl-L-histidyl-L-lysine) present in human fluids
What the Human Trial Record Shows This compound has a documented history in human clinical research that distinguishes it from the vast majority of synthetic research peptides, which have never been tested in human subjects
McTiernan, N., Kjoss, I., & Arnesen, T
Elevated MOTS-c levels in senescent cells, which are exposed to these peptides, increased mitochondrial respiration and some senescence-associated secretory phenotypes (SASP) in the former, suggesting that mitochondria-secreted peptides exert a therapeutic effect by targeting mitochondrial energy and SASP production in senescent cells 50
This means that instead of these macronutrients going unused, B12 helps them fuel your body for extra energy
