PT-141 (Bremelanotide) is a cyclic heptapeptide and metabolite of Melanotan II (MT-II), supplied as a lyophilized powder in a 10mg vial requiring reconstitution before research use. Unlike MT-II, which is a non-selective melanocortin agonist binding across MC1R through MC5R, PT-141 is studied primarily for its selective activity at MC4R — the melanocortin receptor subtype expressed in hypothalamic regions associated with sexual arousal and desire. This central nervous system mechanism distinguishes PT-141 from peripheral vascular approaches to sexual function research, making it relevant in studies examining neurological pathways of sexual motivation. Every batch is independently lab tested and ships with a Certificate of Analysis.

What are the Potential Effects of PT-141 Peptides?
Male Sexual Function Research
In preclinical and clinical research, MC4R activation by PT-141 has been associated with pro-erectile effects in male models — an effect documented during early MT-II tanning research and subsequently the primary driver of PT-141's development as a standalone compound. Research examines both the neural pathway (hypothalamus → spinal cord → peripheral nerve) and the degree of selectivity compared to MT-II's broader melanocortin profile.
Female Sexual Function Research
PT-141 is studied in female research models for effects on sexual arousal, desire, and responsiveness — applications that led to Bremelanotide's eventual development as a pharmaceutical intervention for hypoactive sexual desire disorder (HSDD) in premenopausal women. Research in this area examines both subjective desire and physiological arousal markers in response to MC4R pathway activation.
CNS-Mediated Sexual Arousal
PT-141's primary studied effect is the activation of MC4R receptors in hypothalamic regions of the brain — specifically the medial preoptic area and paraventricular nucleus — that are associated with sexual arousal and motivation. Unlike phosphodiesterase inhibitors that work through peripheral vascular dilation, PT-141's mechanism is centrally mediated, making it relevant for research on the neurological basis of sexual desire rather than its vascular expression.
Appetite & Metabolic Secondary Effects
As a melanocortin receptor agonist with some activity beyond MC4R, PT-141 is also examined in research for secondary effects on appetite regulation and metabolic signaling — though these effects are less pronounced than with the non-selective MT-II. Studies investigating the relative selectivity of PT-141 vs MT-II across the melanocortin receptor family contribute to understanding which receptor subtype drives which observed effect.

PT-141 Research Overview
Acting through central nervous system pathways, PT-141 is widely examined for its influence on desire and arousal signals. It works by interacting with melanocortin receptors in the brain, rather than focusing on blood flow mechanisms.
In research settings, PT-141 is often associated with increasing sexual motivation and responsiveness in both men and women. It is also explored in studies related to low libido, particularly in cases involving reduced desire and psychological factors.
Beyond libido support, PT-141 is being studied for its potential role in improving sexual performance, including in individuals who may not respond to traditional approaches. Its mechanism allows it to address both mental and physical aspects of sexual function.
Additionally, PT-141 is known for relatively quick onset in research applications, with effects observed within a short time after use. Its dual impact on neurological and physiological pathways makes it relevant in a wide range of studies.
Due to its targeted neurological action and stable profile, PT-141 is suitable for extended research where desire, performance, and response are key areas of focus.

Frequently Asked Questions
PT-141 Peptides are synthetic peptides designed to support desire and libido through central nervous system activity. These peptides are a form of lyophilized powder, requiring reconstitution before use. PT-141 acts on melanocortin receptors, which play a role in sexual arousal and function, targeting both male and female sexual wellness. Packaged in 10mg vials, they are verified with a Certificate of Analysis for quality assurance, making them a reliable choice for individuals seeking intimacy-focused support.
PT-141 (Bremelanotide) is priced at ₡56,810 per 10mg vial at Peptides Costa Rica, in USD. With a 15% bulk discount on orders of five or more vials, the per-vial cost drops to ₡48,875 — a saving of ₡43,125 on a five-vial order.

PT-141 (Bremelanotide) is a direct metabolite of MT-II (Melanotan II) — it was identified when researchers studying MT-II's tanning effects observed that a metabolic breakdown product retained the sexual function effects with less melanogenesis activity. The key difference is receptor selectivity: MT-II is a non-selective melanocortin agonist binding across MC1R, MC3R, MC4R, and MC5R simultaneously — producing tanning, appetite suppression, and sexual effects in parallel. PT-141 has a more selective profile favoring MC4R, reducing the melanogenesis signal while retaining the CNS-mediated arousal effects that MC4R drives. Researchers studying sexual function with minimal pigmentation effects use PT-141; those studying the full melanocortin receptor profile or tanning mechanisms use MT-II. Both are available at Peptides Costa Rica.
PT-141 is studied for CNS-mediated sexual arousal and desire via MC4R activation in the hypothalamus; pro-erectile effects in male research models through the hypothalamic-spinal-peripheral pathway; sexual desire and responsiveness in female research models, including research paralleling the clinical development of Bremelanotide for hypoactive sexual desire disorder (HSDD); comparative melanocortin receptor selectivity studies examining PT-141 vs MT-II across the MC receptor family; and secondary appetite and metabolic effects associated with its residual MC3R/MC4R activity.
PT-141 binds primarily to MC4R receptors in hypothalamic brain regions — particularly the medial preoptic area and paraventricular nucleus — associated with sexual arousal and motivation. MC4R activation in these regions initiates a descending neural signal through spinal cord pathways that influences erectile and arousal physiology peripherally. This central mechanism is distinct from PDE5 inhibitors like sildenafil, which act peripherally on vascular smooth muscle. PT-141's CNS mechanism makes it relevant for research on the neurological origins of sexual desire rather than its end-organ vascular expression.
PT-141 and Kisspeptin-10 both feature in sexual function and arousal research but act at entirely different points in the neurological hierarchy. PT-141 acts at the hypothalamic MC4R level to directly stimulate arousal pathways. Kisspeptin-10 acts upstream at the GnRH neuron level — stimulating GnRH release which drives LH and FSH, which in turn regulate gonadal hormone production. Kisspeptin-10 research in sexual function focuses on the hormonal regulation of desire through the HPG axis; PT-141 research focuses on direct CNS arousal signaling independently of gonadal hormone levels. Both are available at Peptides Costa Rica — Kisspeptin-10 10mg is priced at $130 per vial.
Unreconstituted PT-141 vials should be stored refrigerated at 2–8°C in lyophilized (powder) form, protected from light and moisture. Freezing is suitable for long-term storage. Once reconstituted with bacteriostatic water, keep the solution refrigerated and use within the timeframe outlined in your research protocol. Avoid repeated freeze-thaw cycles and minimize light exposure during handling.
