A simple way to think about the current theoretical risk is: Lower theoretical concern: BPC-157 Moderate theoretical concern: TB-500 and thymosin beta-4 fragments Higher theoretical concern: GH/IGF-1-stimulating compounds, such as CJC-1295, ipamorelin, and MK-677 Not primarily a cancer concern: GLP-1 agonists, such as semaglutide, tirzepatide, and retatrutide, except in individuals with MEN2 or medullary thyroid cancer risk Does GHK-Cu cause copper toxicity
