In mice lacking Nav1.6 channels, I NaP currents are reduced by 39%, and I NaR currents are suppressed by 76%, leading to the loss of subthreshold oscillations, impedance resonance, and both spontaneous and evoked rhythmic firing (Enomoto et al., 2006, 2007)
Prescription medications like Wegovy (semaglutide) and Mounjaro (tirzepatide) are designed to mimic GLP-1's effects so precisely that the body essentially treats them as the real thing
These results suggest there is no excess cardiovascular risk with tirzepatide and are consistent with the improvements of numerous surrogate markers of cardiovascular health, including weight reduction, glycemic control with less hypoglycemia, blood pressure reduction, and improvements in the lipid profile
They may also be sipping less water, skipping meals without meaning to, or feeling too nauseous to drink enough
Substantial weight loss naturally increases testosterone production as fat tissue (and its aromatase enzymes) diminishes
These results highlight the role of MOTS-c in energy balance
