Cell ageing is largely caused by oxidative stress
Once reconstituted from its lyophilised form, the peptide becomes vulnerable to hydrolysis, oxidation, aggregation, and microbial contamination making correct storage, handling, and adherence to sponsor-validated stability data essential for safety
This tripeptide, also called GHK, is made of a chain of three amino acids: glycine, histidine, and lysine
At 5mg/mL, that same 0.25 mg dose requires only 5 units, a smaller and harder-to-read measurement
tendon-to-bone integration also noted in preclinical settings (Staresinic 2003
Selank is the most-studied peptide on this pathway
