Carnosine vs Ghrelin

Dipeptide that buffers lactic acid in muscle during high-intensity exercise; chelates metal ions; prevents and reverses protein glycation; scavenges aldehyde oxidative byproducts

A naturally occurring dipeptide in muscle and brain tissue with multiple anti-aging and performance benefits. Buffers muscle acidity during exercise and prevents glycation-related aging damage.

Must be acylated at Ser3 (by GOAT enzyme) for GHSR-1a binding. Receptor activation in the pituitary stimulates GH release; hypothalamic action via NPY/AgRP neurons increases appetite and reduces energy expenditure.

An endogenous 28-amino acid peptide hormone produced primarily by gastric oxyntic cells. Functions as both the primary hunger signal and a potent GH secretagogue. The natural ligand for the growth hormone secretagogue receptor (GHSR-1a).
