PT-141 Single Vial
Melanocortin Research · single vial · no minimum order
PT-141 is available as an individual vial shipped from our UK facility, so a laboratory can take one vial rather than a wholesale box. Every single vial is the same material as the factory-direct range, held in the UK for tracked next-working-day delivery, and supplied strictly for laboratory research.

The wholesale format is a multi-vial factory-direct box with a lower per-vial cost and a minimum order quantity. See PT-141 factory direct.
About PT-141
PT-141, also known as Bremelanotide or Vyleesi, is a research peptide classified under sexual health compounds for laboratory investigation. This synthetic peptide has garnered significant attention in research settings for its unique mechanism of action and potential applications in sexual function studies. The compound operates through activation of melanocortin receptors in the central nervous system, specifically targeting MC3 and MC4 receptors. Research indicates that PT-141 modulates neurotransmitter release pathways involved in sexual function regulation, distinguishing it from other approaches that focus on vascular mechanisms. This central nervous system-mediated action represents a novel pathway for sexual health research. Clinical research has demonstrated PT-141's effects in laboratory models, with studies reporting increased sexual desire, improved sexual arousal, enhanced erectile function, and increased frequency of satisfactory sexual events. Some research also suggests potential mood enhancement effects. The evidence grade is classified as B, reflecting several human clinical trials that have investigated the compound's efficacy, particularly in research models of hypoactive sexual desire disorder (HSDD). Studies indicate significant improvements in sexual desire scores compared to placebo controls in research settings. However, the literature emphasises that additional research is needed to fully characterise long-term safety profiles and comprehensive efficacy data. The compound's unique central nervous system mechanism makes it a valuable tool for researchers investigating sexual health pathways and neurological aspects of sexual function regulation.
Mechanism
PT-141, also known as Bremelanotide, works by activating melanocortin receptors in the central nervous system. This activation leads to increased sexual arousal and desire by modulating neurotransmitter release. It primarily targets the MC3 and MC4 receptors, which are involved in sexual function regulation.
Reported research findings
- Increased sexual desire
- Improved sexual arousal
- Enhanced erectile function
- Increased frequency of satisfactory sexual events
- Potential mood enhancement
Why a single vial
Pilot and method work
A single vial covers assay development, method validation or a short pilot run without committing to a wholesale quantity of PT-141.
UK held, fast turnaround
Vials ship from our UK facility on a tracked service, so a study is not waiting on an international consignment or a customs queue.
Same material as the box
Single vials are drawn from the same vetted manufacturing source as the factory-direct range, with the same batch documentation.
Predictable spend
Small laboratories and independent researchers can budget one vial at a time rather than a full minimum order quantity.
Storage and handling
Before reconstitution
Store the sealed lyophilised vial at 2 to 8°C, protected from light and moisture. Longer term storage at minus 20°C is common laboratory practice.
After reconstitution
Reconstituted solution is held refrigerated at 2 to 8°C and used within the window appropriate to the compound. Avoid repeated freeze and thaw cycles.
Reconstitution
Bacteriostatic water is the usual diluent. Our reconstitution calculator works out the diluent volume for a given target concentration.
Documentation
Every vial carries a batch number for traceable laboratory records, and independent verification is encouraged.
See the reconstitution guide and the calculator.
FAQs
Can I order a single vial of PT-141 without a minimum order?+
Yes. The single-vial range exists precisely so a laboratory can take one vial of PT-141 rather than a full wholesale box. There is no minimum order quantity on this format.
How quickly does a PT-141 single vial ship in the UK?+
Single vials are held in our UK facility and dispatched within 24 hours of a cleared payment on working days, on a tracked UK service. Orders placed at the weekend go out on the next working day.
How does the single vial differ from the factory-direct box?+
The compound and the manufacturing source are the same. The factory-direct box is a wholesale multi-vial pack with a minimum order quantity and a lower per-vial cost, while the single vial is one vial from UK stock for small-scale or pilot work.
What purity is stated for PT-141?+
99%+ manufacturer-stated purity. Buyers are encouraged to run independent third-party verification, and our testing directory lists laboratories that perform it.
Is this PT-141 vial for human use?+
No. Every PeptX product, including the single-vial range, is supplied strictly for laboratory research. It is not for human consumption, diagnosis, treatment or any clinical use.
What is PT-141?+
PT-141, also known as Bremelanotide, is a research peptide that activates melanocortin receptors in the central nervous system. It is classified under sexual health compounds and is used exclusively for laboratory research investigating sexual function pathways.
How does PT-141 work?+
PT-141 works by activating MC3 and MC4 melanocortin receptors in the central nervous system, which modulates neurotransmitter release involved in sexual function regulation. This represents a unique central nervous system-mediated mechanism for sexual health research.
What is the half-life of PT-141?+
Specific half-life data for PT-141 is not definitively established in the current research literature. Researchers should consult the latest pharmacokinetic studies for the most current information on the compound's duration of action in research models.
How is PT-141 stored?+
PT-141 should be stored according to standard peptide storage protocols in laboratory settings. Lyophilised powder should be kept in appropriate laboratory storage conditions, and reconstituted solutions should be handled according to institutional research guidelines.
Strictly for laboratory research. Not for human consumption, diagnosis or treatment.
