One (blue/green) for injecting, typically longer for intramuscular administration
Unlike GHK-Cu, which has decades of preclinical and some cosmetic data, AHK-Cus peptide-specific evidence is essentially one ex-vivo / in-vitro study [1] , and no study of any kind has injected it
IGF-1 LR3 Research Applications The most established application of IGF-1 LR3 is as a growth factor supplement in serum-free mammalian cell culture, where Morris and Schmid (Biotechnology Progress, 2000) compared LongR3 against insulin in CHO lines expressing recombinant proteins, and where it is widely used as an insulin replacement at much lower concentrations
High insulin levels can contribute to atherosclerosis (hardening and narrowing of the arteries), high blood pressure, and abnormal lipid profiles (elevated triglycerides and decreased HDL cholesterol), all of which are risk factors for heart disease and stroke
