About this item

PT-141, also known as bremelanotide, is a research peptide most commonly associated with libido and the central regulation of sexual response. It is selected for projects involving the melanocortin system, behaviour and receptor communication in the central nervous system.

Its cyclic structure makes it a useful material for comparing melanocortin receptor activity. The product is supplied as a lyophilised vial, and every batch is supported by purity testing and analytical documentation. For research use only.

Form: lyophilised powder in a type I glass vial with a chlorobutyl rubber stopper and an aluminium seal. Structure: cyclic heptapeptide closed by a lactam bridge. Purity: not less than 98% by HPLC. Appearance: white to slightly off-white cake.

The peptide content of the vial is stated on the batch label and in the certificate of analysis, which covers HPLC and mass spectrometry results. Vials are packed individually and without solvent; bacteriostatic water is ordered separately.

Unopened vials are stored at -20 °C, in the dark and at low humidity. Bring the vial to room temperature before opening so that water vapour does not condense on the cold cake.

Reconstitution uses bacteriostatic or sterile water, added slowly down the inner wall of the vial; the stream is never directed onto the cake. The vial is not shaken, because foaming promotes loss of peptide activity, and a gentle swirl until the solution is clear is enough. The solution is kept at 2-8 °C, protected from light, and treated as usable for a limited period; for longer holding it is aliquoted and frozen so that repeated thawing is avoided.

This product is supplied for research and laboratory purposes only. It is not a medicinal product, dietary supplement, cosmetic or medical device. It is not intended for ingestion or for any use in humans or animals.

The material may be handled only by personnel trained in working with chemical reagents, in a designated area and with personal protective equipment. Keep out of reach of children and unauthorised persons. Sold exclusively to research users.

Questions

Before you order

Answers to the questions that matter before ordering this position.

Peptides are short chains of amino acids offered here as raw materials and reference compounds for laboratory research and further processing. They are not medicines, dietary supplements or cosmetics and are not intended for human or veterinary use. Match the identity, CAS number, sequence, form, declared purity, amount and storage conditions on this page to your protocol. We do not select a material by a health goal or describe an expected effect; we can explain the specification, batch documentation and handling requirements before you order.

Every batch we accept has a certificate of analysis of its own — not one written for the product line — with identity and purity documented by HPLC or mass spectrometry, and a lot number traceable to the manufacturer. Write to us with your order number and we will send the documentation for the batch you were sent.

Unopened vials are stored at -20 °C, in the dark and at low humidity. Bring the vial to room temperature before opening so that water vapour does not condense on the cold cake. Reconstitution uses bacteriostatic or sterile water, added slowly down the inner wall of the vial; the stream is never directed onto the cake.… Follow the supplier's own instruction on the packaging; it is reproduced on this page where the supplier provided one. We match storage and shipping to the material, cold-chain positions included, so what reaches you still matches its certificate.

We ship with InPost and DPD, and parcels usually arrive within 2–5 working days. An order placed before 13:00 goes out the same working day. Delivery is free over 46 €; below that it starts at 6 € to an InPost locker. You get a tracking number and a tracking link once the parcel is sent. Checkout shows the methods available for this order: online payment or bank transfer and, with selected delivery methods, payment on delivery. The final method selection, delivery charge and full amount are shown before you confirm the purchase.

You have 14 days to withdraw from the purchase without giving a reason, provided the packaging is unopened and the item is complete and intact. Materials delivered in sealed packaging cannot be returned once the seal is broken. Return postage is yours unless the item was faulty or not what you ordered; the refund goes back the way the payment came, within 14 days of the return arriving.

We supply quantities from a single vial upwards and quote for repeat and bulk orders. Send us the position, the quantity and the delivery address, and we will answer specification and handling questions before the order rather than after it.
