Supplier: Prax Peptides
Purity: 99%+
Formulation: Spray Solution (Total dosage 10 mg — specify total volume and per-spray dosage on final product)
Molecular Formula: C₅₀H₆₈N₁₄O₁₀

Scientific Overview & Mechanism of Action

PT-141 (Bremelanotide) is a synthetic cyclic heptapeptide and potent agonist of the melanocortin receptor family, primarily the MC₄R subtype. Distinct from compounds that act through vascular pathways, PT-141 is proposed to modulate sexual function via central mechanisms in the hypothalamus.

Activation of the MC₄R receptor initiates a cascade of intracellular signaling within the brain’s arousal centers, making PT-141 a valuable compound for research on neuroendocrine control of desire and behavior.

The spray solution format provides a convenient, non-invasive route for administration, offering researchers flexibility in dosing and enabling comparative studies on absorption, onset, and systemic distribution versus injectable delivery models.

Key Research Applications and Pre-Clinical Findings

Central Nervous System Modulation
Investigated for its role in influencing hypothalamic pathways that regulate arousal and reward responses, contributing to the broader understanding of central sexual function.

Melanocortin Receptor Pathway Studies
Used as a model compound for examining the melanocortin signaling network, including its intersections with energy balance, mood, and inflammatory modulation.

Arousal Activation
Pre-clinical research suggests that PT-141 may induce measurable appetitive and consummatory behaviors, supporting its value as a central activator in studies of desire and motivation.

Alternative Delivery Route Studies
The spray solution is commonly utilized in experiments exploring mucosal absorption, bioavailability, and receptor engagement without parenteral injection.
