1.25 - 1.25 mg
Part of the pooled 1.25/1.75mg dose group that showed statistically significant improvement over placebo.
Research focus
Central sexual arousal pathway
Observed window
30-60 min onset (on-demand)
Administration
As needed, ≥45 min before activity
Primary pathway
MC3R / MC4R
Dose data from Clayton et al. 2016 (dose-finding RCT) and the RECONNECT Phase 3 program (Kingsberg et al. 2019). For research use only.
PROTOCOL BENEFITS
◆
Activates MC3R and MC4R receptors in the hypothalamus and limbic system, engaging central nervous system pathways associated with sexual arousal and motivation.
◆
Works through a completely separate pathway from vascular-acting compounds, opening a route where those mechanisms fall short.
◆
Backed by Phase 3 trials across more than 1,200 participants, with dose-responsive improvements in desire and arousal.
SCIENCE
PT-141 is built from the same backbone as your body's own alpha-MSH. Instead of working on blood vessels, it goes straight to the source — activating melanocortin MC3R and MC4R receptors in the hypothalamic and limbic regions that drive arousal.
Most compounds in this space work on blood flow. PT-141 doesn't touch that pathway at all — it's mediated entirely through the central nervous system, which is why it shows activity even in models where vascular-acting compounds come up empty.
WHAT TO EXPECT
Effects have been observed within 30-60 minutes in research models — this is an on-demand compound, not a daily accumulation protocol. Phase 3 research tracked outcomes across a 24-week study window.

Available in 10mg. For research use only. Full documentation included with every order.
