PT-141 (Bremelanotide) 10mg – Melanocortin Receptor Agonism & CNS Signaling Research

Description

What is PT-141 & CAS 189691-06-3?

Biological research identifies PT-141 (Bremelanotide) as a unique cyclic heptapeptide analog of Alpha-Melanocyte Stimulating Hormone ($\alpha$-MSH). Registered under CAS 189691-06-3, this compound is a synthetic derivative of Melanotan II, specifically engineered by removing the C-terminal amide group. Unlike other performance peptides that act on the vascular system, PT-141 is distinguished by its ability to act directly on the central nervous system, making it a primary subject for studies involving neuroendocrine signaling and sexual dysfunction.

The chemical integrity of our PT-141 10mg vials is strictly preserved through a high-precision lyophilization process. This professional freeze-drying technique stabilizes the peptide into a vacuum-sealed white cake, preventing molecular degradation and ensuring high potency during global transit. At 99Purity-Peptide, we provide a clinical-grade research medium that enables high-fidelity data collection for investigations into libido enhancement and physiological vitality.

PT-141 Mechanism of Action and Research

Functioning as a non-selective agonist of the melanocortin receptors, PT-141 primarily targets the MC3R and MC4R receptors located in the hypothalamus. In a laboratory environment, this interaction is uniquely researched for its ability to trigger downstream signaling pathways that regulate sexual behavior and desire. By acting on the CNS rather than the cardiovascular system, PT-141 provides a distinct experimental pathway for studying erectile function and female sexual arousal disorder (FSAD) without the blood pressure complications associated with traditional phosphodiesterase inhibitors.

Deepening the investigation into metabolic and neuro-behavioral regulation, contemporary trials utilize Bremelanotide to evaluate its influence on inflammatory responses and energy balance. Emerging data from high-fidelity laboratory trials suggest that MC4R activation may offer broader insights into systemic vitality and the management of neuroendocrine decline. Its role in the growth-performance-enhancement category makes it a critical subject for research into holistic physiological performance and the restoration of natural libido rhythms.

PT-141 FAQ

How does PT-141 differ from Melanotan II in research?

While both act on melanocortin receptors, PT-141 is a metabolite of Melanotan II that lacks the C-terminal amide. In research settings, this means PT-141 focuses almost exclusively on MC3R and MC4R (desire and arousal) rather than MC1R (skin tanning), making it a more specific tool for vitality studies.

What is the expected onset of action for PT-141 in laboratory models?

Studies typically observe physiological responses within 2 to 4 hours after administration. Researchers document this timeline to understand the peptide’s pharmacokinetics and its sustained signaling effects on the hypothalamus.

What is the recommended reconstitution for PT-141 10mg?

To preserve the 99% purity, researchers use sterile bacteriostatic water. The liquid should be added slowly, allowing it to run down the side of the vial. Gently swirl—never shake—until the lyophilized cake is fully dissolved. Once reconstituted, it must be kept refrigerated at 2-8°C.

Is PT-141 stable at room temperature?

In its lyophilized (freeze-dried) state, PT-141 is highly stable and can withstand room temperature during shipping. For long-term preservation of its chemical integrity, it should be stored in a freezer at -20°C upon arrival at the laboratory.

Does PT-141 affect blood pressure?

Unlike many performance enhancers, PT-141 acts on the brain rather than the heart. However, research models sometimes show transient increases in blood pressure. Scientists monitor these variables to study the safety profile of melanocortin agonists in clinical models.
