The protocol
What is PT-141.
PT-141 (Bremelanotide) is a synthetic peptide, structurally related to melanocortin, that is compounded for off-label use in women's low sexual desire (also known as HSDD). Unlike therapies that work primarily on blood flow, PT-141 acts on melanocortin receptors in the central nervous system to increase arousal signaling. Off-label use is not FDA-approved for this purpose; your clinician reviews risks, benefits and alternatives during intake. Individual results vary.

The mechanism
How it works
N°01
Central nervous system activation
PT-141 binds melanocortin receptors (MC3R/MC4R) in the brain, the circuitry that initiates sexual desire — a mechanism distinct from purely vascular therapies.
N°02
Desire, not just response
Because it acts upstream in the arousal pathway, PT-141 is often used by women whose primary concern is low libido rather than physical response alone.
N°03
Works independent of blood flow
PT-141 does not rely on vascular dilation, so it can be considered for women who haven't found relief with other approaches.
