Carnosine vs Ipamorelin

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.

Ipamorelin binds to the ghrelin receptor (GHSR-1a) and stimulates dose-dependent GH release with a clean hormonal profile. Unlike GHRP-6 or hexarelin, it does not significantly stimulate appetite-related pathways or cortisol secretion at standard research doses. This selectivity makes it a frequently studied peptide for protocols where hormonal side-effect profiles are a consideration.

Ipamorelin is a selective growth hormone secretagogue and ghrelin receptor agonist. It stimulates pulsatile GH release from the anterior pituitary with high selectivity — producing minimal effect on cortisol, prolactin, or ACTH compared to earlier GHRPs. It is commonly researched for its role in supporting body composition, recovery, and lean mass maintenance.
