Research Applications & Benefits
- Acts centrally in the brain
- Activates MC4R in hypothalamus
- Unique CNS mechanism
What is PT-141 (Bremelanotide)?
Works in the brain, not blood vessels — activating MC4R in the hypothalamus.
Listed vial contents: 10mg. These are supplied quantities, not administration doses. Current pricing and availability are shown in the strength selector.
What mechanisms are being studied?
PT-141 (Bremelanotide) is a cyclic heptapeptide melanocortin receptor agonist that primarily targets MC4R and MC3R in the hypothalamus. Unlike PDE5 inhibitors (Viagra/Cialis) which act on blood vessels, PT-141 works centrally in the brain to modulate sexual arousal pathways.
What are the research questions?
- Hypoactive Sexual Desire Disorder (HSDD): FDA-approved as Vyleesi® (2019) for premenopausal women with acquired, generalized HSDD.
- Erectile dysfunction (male): Phase 2/3 data showed efficacy in ED, including in patients who failed PDE5 inhibitors.
- Sexual dysfunction research: Unique mechanism of action (brain-based vs vascular) makes it valuable for studying central sexual arousal pathways.
What does the published work describe?
Kingsberg SA et al. (Obstet Gynecol 2019) — RECONNECT trial: Statistically significant improvement in sexual desire and associated distress. Diamond LE et al. (Int J Impot Res 2004) — Phase 2 ED trial: 67% erection response vs 32% placebo, including 33% response in PDE5 non-responders.
What are the limits of this evidence?
The research described concerns the cited experimental materials and models, not proof that this supplied vial is a treatment. Cell or animal findings do not establish human benefits. Clinical findings, where cited, apply to the tested formulation and population; they do not validate this research product for human use.

How should I check lot documentation?
Match the product, strength and lot to an original analysis document. Literature describes experimental findings; it does not verify the contents of this inventory. A report is evidence only for the product, strength and lot it names.
How is PT-141 (Bremelanotide) handled in the lab?
For PT-141 (Bremelanotide), record the product code PT141, selected strength and lot before opening. Follow the material-specific safety data sheet and laboratory SOP, with appropriate gloves, eye protection and containment. For a documented dry preparation, let the sealed vial equilibrate before opening to reduce condensation; minimize time open and use clean, compatible vessels.
Choose a solvent for PT-141 (Bremelanotide) from the documented sequence or chemical identity, salt form and assay requirements. Test a small portion first and record pH, solvent composition and clarity. Do not assume one diluent works for every research material; include a solvent-only control and establish compatibility before using the stock in an assay.
For PT-141 (Bremelanotide), calculate mass concentration as measured material mass divided by final solution volume. Calculate molarity only with a documented molecular weight for the supplied chemical form; the catalog lists 1025.18 g/mol as a reference, not lot confirmation. Where available, use matched-lot net content rather than treating chromatographic purity as a mass correction. Record both stock concentration and subsequent dilution factors.
Use the documented storage conditions for the supplied PT-141 (Bremelanotide) form and lot. For a documented lyophilized preparation, keep the vial sealed and protected from moisture; for solutions, validate temperature, light exposure and holding time in the assay. Use compatible single-use aliquots when appropriate to reduce repeated freeze-thaw. No universal temperature or 28-day solution shelf life is established by the catalog name.
A PT-141 (Bremelanotide) laboratory protocol should record identity, product code PT141, strength, lot, applicable analysis results, solvent and pH, stock concentration, dilution sequence, vessel type, storage history and assay endpoints. Include vehicle and reference controls, independent replicates and predefined acceptance criteria. Separate handling validation from biological interpretation; these notes do not provide administration or dosing instructions.
Research Use Only. Not for human consumption, therapeutic, veterinary or any in-vivo use.

Quality & Verification
PT-141 (Bremelanotide) has a catalog purity specification of ≥99%; this is not a measured result for every vial. Match the product, exact strength, batch and lot to its analysis record and read only the reported fields. HPLC peak-area purity, measured content and endotoxin are separate measurements. A blank field means no result is reported, not zero or passed. A purity percentage alone does not establish identity, sterility or suitability for human use.
