In STEP-1 (semaglutide), lean mass decreased by ~9.7% while fat mass fell by ~19.3%, with the proportion of lean mass increasing by ~3 percentage points ( Limited preclinical and clinical data, particularly from MRI-based studies, suggest that skeletal muscle changes induced by GLP-1RAs may be adaptive
Peak semaglutide concentrations typically occur 24-48 hours after injection, which is why many patients report the strongest appetite suppression midweek
Most clinical studies show that while it can lead to a small amount of additional weight loss, it is not nearly as powerful as prescription medications like Ozempic, Wegovy, Mounjaro, or Zepbound

Whether youre recovering from an injury, managing joint discomfort, or looking to optimize your overall wellness, this regenerative peptide can be a powerful addition to your care plan
