GLP-1/GIP dual agonists like tirzepatide (Mounjaro) activate both GLP-1 and GIP receptors simultaneously
GPx activity was determined using the Ransel glutathione peroxidase assay (Randox Laboratories, Crumlin, UK), following the manufacturers instructions and also adjusted to a 96-well plate
Potent mTOR Activation : Both leucine and dileucine activate the mTOR pathway, but dileucine creates a more robust anabolic response, as evidenced by greater increases in muscle protein synthesis rates
In aged rat models, treatment increased activity of antioxidant enzymes like superoxide dismutase (SOD), glutathione peroxidase, and glutathione-S-transferase, improving overall oxidative defense
However, it's important to note that B12 injections should not be used as a substitute for a healthy diet and lifestyle
