PT-141
B
Semaglutide
A side-by-side look at what PT-141 and Semaglutide actually are, so you can see where they overlap and where they genuinely differ before deciding which is worth researching further — no score, no “winner,” just the facts next to each other.
FDA status
PT-141
FDA-approved — Vyleesi, for premenopausal HSDD only (the compounded version this board ranks is not FDA-reviewed)
Semaglutide
FDA-approved — Wegovy & Ozempic (the compounded version this board ranks is not independently FDA-reviewed)
Typical dose / use
PT-141
Vyleesi's approved dose: 1.75 mg SC as needed, ≤8 doses/month (the compounded version has no agency-set dose)
Semaglutide
0.25–2.4 mg/week (FDA label range)
Product forms
PT-141
Injectable — Vyleesi ships as a pre-filled autoinjector; the compounded version is a reconstituted powder vial
Semaglutide
Injectable; also an oral tablet (Wegovy)
How it works
PT-141
Activates melanocortin receptors — chiefly MC4R in the hypothalamus — believed to trigger dopamine release that increases sexual desire, a brain-mediated mechanism distinct from PDE5 inhibitors, which act on blood flow.
Semaglutide
Activates the GLP-1 receptor alone — one target, versus tirzepatide's two — slowing gastric emptying, boosting insulin release when blood sugar is high, and reducing appetite.

Every fact above is reused from PT-141's and Semaglutide's own compound guides, not re-derived here. A highlighted value means that number is objectively larger or smaller — more providers ranked, a lower standing price — never a claim about which compound is “better.” Cost and provider counts are read live from each compound's own board and can change without notice.
