PT-141 10mg Nasal Spray peptide Details
PT-141 10mg Nasal Spray — Research Grade | Pre-Formulated Liquid Solution
This nasal spray formulation delivers PT-141 (Bremelanotide) as a pre-formulated, sterile liquid solution for research use. No reconstitution is required — the product arrives ready for laboratory application via the nasal spray delivery format.
PT-141 (Bremelanotide) is a cyclic heptapeptide melanocortin receptor agonist developed from Melanotan II. It was discovered serendipitously during Melanotan II research when subjects reported unexpected effects on sexual arousal. It primarily acts on MC3R and MC4R receptors in the CNS. PT-141 has been studied extensively in the context of sexual function research in both male and female preclinical models.
Nasal spray format note: This product is supplied as a metered-dose nasal spray bottle for research convenience. The intranasal delivery format for melanocortin receptor agonists has been explored in preclinical and early clinical research. All use is strictly for laboratory and research purposes only.
⚠️ For Research Use Only — Not for human consumption. Requires 2nd Day Air or Next Day Air shipping (no ground shipping available).
T-141 10mg Nasal Spray peptide Scientific Research
- Melanocortin Receptor Pharmacology
Used to investigate GPCR-mediated signaling, PT-141 allows researchers to explore agonist binding profiles, EC50 behavior, receptor desensitization, and second-messenger responses (e.g., cAMP, phospho-ERK). Its structure makes it suitable for receptor selectivity studies involving MC3R and MC4R. - Central Nervous System (CNS) Pathway Exploration
PT-141 is employed in rodent models to study hypothalamic signaling, neuromodulation, and neuroendocrine axis regulation. Experimental readouts include immediate early genes (IEGs), CREB activation, and behavioral assays linked to hypothalamic and limbic circuits. - Inflammatory Signaling & Immune Modulation
By targeting MC1R, PT-141 is also examined in immune cell models to evaluate macrophage phenotype modulation, cytokine expression profiles, and systemic inflammatory response markers. - Pigmentation & Melanocyte Function
In melanocyte-focused studies, PT-141 is used to map melanocortin pathway effects on melanin production, enzyme regulation, and UV-response signaling through cAMP/PKA/MAPK pathways.

Handled correctly, stability holds
All peptides are supplied as sterile, lyophilized powder and are stable when handled correctly.
Store vials in a cool, dry place away from heat and direct sunlight.
For optimal longevity, keep lyophilized peptides refrigerated to help maintain integrity.
Use an appropriate research diluent (for example, BAC water). Store the reconstituted solution in the refrigerator and use within 20–30 days for best stability.
Minimize exposure to moisture and repeated freeze–thaw cycles. Follow your institution's safety procedures when handling research materials.
Frequently Asked Questions
PRODUCT & PURITY
This product is offered for laboratory and research use only. It is not intended for human consumption, medical use, therapeutic use, or veterinary use.
Yes, all of our products are sterile and sealed with a sterility plug and safety cap.
Our products undergo quality control internally at our lab and then 3rd party tested at Bioviridian (at their Texas facility) prior to shipment. All of our COA's are then posted on our site immediately upon receipt.
99% or higher. Period. The expected purity is listed on the individual product page or Certificate of Analysis, when available.
No. We are a manufacturing company and because these products are sold for research purposes only, we do not provide dosing, administration, or medical-use guidance.
Unless specifically stated otherwise, these products are not approved by the U.S. Food and Drug Administration for therapeutic or diagnostic use.
STORAGE & STABILITY
As a lyophilized powder, peptides are stable. Delays in shipments up to 7 days will have zero to minimal impact on efficacy of peptides. Most precautionary efforts must be made to maintain temperature consistency once reconstituted.
Store the product according to the storage recommendations provided on the label or accompanying documentation in your shipment. Proper storage helps maintain product integrity during its shelf life. Most peptides have an expiration date of 2 years if kept unreconstituted (lyophilized powder).
SHIPPING
Shipping times vary based on your location and the shipping method selected at checkout. We offer shipping options between 1 and 5 days.
No.
Once your order is processed, you will receive a shipping confirmation email with tracking information.
