MD Weight Loss Rx offers high-quality lifestyle medications that do not require a prescription or a visit to the pharmacy. Semaglutide sodium has been used to treat diabetes for more than a decade as a GLP1-RA (glucagon-like peptide 1 receptor agonist). It has been known for some time that these agents cause weight loss, but Semaglutide Sodium appears to be the "best-in-class" GLP-1 RA for weight loss and has recently been approved for use under the brand name Wegovy by the FDA.
