Frequently asked questions
Is PT-141 the same as Viagra?
No. Different mechanism. PT-141 acts on CNS melanocortin receptors. Sildenafil acts on peripheral vascular smooth muscle via PDE5 inhibition. Not interchangeable.
Can I get Vyleesi on the NHS?
Vyleesi is FDA-approved in the US but has no UK marketing authorisation. The NHS does not prescribe it.
