PT-141 API Technical Information
| CAS Number | 189691-06-3 |
|---|---|
| Molecular Formula | C50H68N14O10 |
| Molecular Weight | 1025.18 g/mol |
| Description | PT-141 (Bremelanotide) is a synthetic cyclic heptapeptide lactam analogue of alpha-melanocyte-stimulating hormone (α-MSH). Its peptide sequence structure is defined as Ac-Nle-cyclo(Asp-His-D-Phe-Arg-Trp-Lys). Unlike traditional compounds that target the vascular system, PT-141 acts as a non-selective melanocortin receptor agonist (primarily targeting MC3R and MC4R) in the central nervous system, making it widely researched for the treatment of sexual dysfunction and hypoactive sexual desire disorder. |

FAQ
What is PT-141?
PT-141 (Bremelanotide) is a synthetic cyclic heptapeptide lactam analogue of alpha-melanocyte-stimulating hormone (α-MSH). It acts as a non-selective melanocortin receptor agonist (primarily targeting MC3R and MC4R) in the central nervous system, and is widely researched for sexual dysfunction and hypoactive sexual desire disorder.
In which supply forms can I order PT-141?
PT-141 is available as bulk raw material and vial-packed research material. Specify the required supply form when requesting a quotation.
Which raw material and vial specifications are available for PT-141?
Raw PT-141 is supplied in quantities from 10 g to 1000 g. Available research vial specifications: 10 mg. Each kit contains 10 vials.
What is the minimum order quantity for PT-141?
The minimum order for raw PT-141 is 10 g. For vial-packed PT-141, the minimum order is 10 vials, equal to one kit.
In what physical form is PT-141 supplied and how is it packaged?
Raw PT-141 is supplied as lyophilized powder in fluorinated bottles, then vacuum packed in aluminum foil bags. Vial-packed research PT-141 is supplied as lyophilized powder in sealed pharmaceutical glass vials, with 10 vials per kit.

We keep kilogram-scale stocks of raw PT-141, normally dispatching within 7 days. Research vials of PT-141 are kept in stock, normally delivered within 7 days. If stock cannot cover your order, we arrange production, usually taking 7 days, with delivery in 7–15 days.
How are bulk PT-141 orders quoted and which wholesale discounts apply?
Raw PT-141 is quoted at gram and kilogram scales. Bulk research-vial orders qualify for wholesale discounts when they reach the applicable order amount. Every first order receives wholesale pricing regardless of its amount, reducing first-order evaluation costs. Quotes reflect specification, quantity, packaging and delivery destination.
Why choose LJH Global as your PT-141 supplier?
LJH Global manufactures PT-141 raw material in-house and independently controls quality for consistent supply. Product purity: 99.77% (HPLC). Batch support includes COA, HPLC and LC-MS reports. Supply ranges from gram-scale raw material to custom milligram research vials for academic research and bulk procurement.
Where can I source PT-141 and request a bulk quotation?
Source PT-141 from China-based supplier LJH Global. Request current bulk pricing through our website inquiry form or WhatsApp. We reply within half an hour during working hours.
What are the structural features and mechanism of PT-141?
PT-141's peptide sequence is defined as Ac-Nle-cyclo(Asp-His-D-Phe-Arg-Trp-Lys). Unlike traditional compounds targeting the vascular system, PT-141 activates melanocortin receptors in the CNS, mainly MC3R and MC4R, as a non-selective agonist.
What are the main research areas for PT-141?
PT-141 is widely researched for the treatment of sexual dysfunction and hypoactive sexual desire disorder due to its action on central melanocortin receptors.
Is PT-141 for human or veterinary use?
No. PT-141 is supplied only as a chemical reagent for in-vitro laboratory research, not for human or veterinary use. LJH Global is not a pharmacy or compounding facility.
