SKU: P41-ER Category:

PT-141 (Bremelanotide) is a cyclic heptapeptide melanocortin receptor agonist derived from the hormone alpha-MSH, with a molecular weight of 1025.18 g/mol. Unlike PDE5 inhibitors, PT-141 works centrally, activating MC3R and MC4R receptors in the hypothalamus to modulate the neural circuits involved in sexual arousal, independent of vascular mechanisms.

Research has examined PT-141 in male and female models of sexual dysfunction, with clinical studies demonstrating receptor-mediated effects on desire and arousal pathways. Its central mechanism of action offers researchers a distinct pharmacological profile for studying the neural basis of sexual response in both sexes.

Each Etched Research vial contains 10mg of lyophilized powder.

Specifications:
– Molecular Formula: C50H68N14O10
– Molecular Weight: 1025.18 g/mol

– Form: Lyophilized powder
– Storage: -20°C (lyophilized); 4°C once reconstituted, use within 30 days

FOR IN VITRO RESEARCH USE ONLY. NOT FOR HUMAN CONSUMPTION, INGESTION, OR ANY IN VIVO USE.

Research at a Glance
  • What it is: A synthetic peptide that switches on melanocortin receptors, a signaling system tied to sexual arousal. In the research literature it is called bremelanotide.
  • Researchers have studied it for: sexual desire and arousal (the main human trial literature) and melanocortin-pathway biology.
  • Evidence level: Real human evidence, but for one narrow use only. Two large phase 3 trials in premenopausal women, plus an FDA approval of a finished prescription drug for that single diagnosis. Outside that, the record is thin.
  • The short version: Bremelanotide is the most human-tested peptide in this catalog. In two large trials researchers watched it raise measured sexual-desire scores and lower related distress in premenopausal women, and regulators later approved a finished drug version for that one use. This page reports what researchers studied. It is not a recommendation to use the compound, and this material is supplied for research only.

Frequently asked questions

Does the product come with instructions?

No. Etched supplies research materials, not use instructions. Each vial ships labeled with the compound name, the labeled amount, and the lot number, and that is what comes in the box. Etched does not provide instructions for use, dosing, or administration for any product, on the label, on this page, or by email. General laboratory handling notes (storage, what bacteriostatic water is) are on the FAQ page at https://etchedresearch.com/faq/. All products are sold for research use only, not for human consumption.

What is the amount of peptide in this product?

The label reads PT-141 10mg. That figure is the labeled net quantity of PT-141 in the vial, supplied as lyophilized (freeze-dried) powder. It is not the weight of the vial and not a reconstituted volume. Where a Janoshik Analytical report exists for a lot, the measured result for that lot is on the report itself, and the reports that exist are listed on the COA page at https://etchedresearch.com/coa/. Etched ships lyophilized powder only.

Are additional supplies needed?

Nothing else is included, and Etched sells the lyophilized compound only. Bacteriostatic water is sterile water with a small amount of benzyl alcohol added, used in laboratory settings to reconstitute lyophilized (freeze-dried) research peptides into solution. Etched does not sell bacteriostatic water as a product. It is described here only to explain the reconstitution step in a research context. Any supplies a laboratory setting requires are sourced by the researcher.

How is purity verified?

By a third-party laboratory, named. Janoshik Analytical confirms compound identity by mass spectrometry and measures purity by HPLC. Etched does not use vague "third-party tested" language without naming the lab. The measured number for a tested lot is on that lot's report, not a mood word. Where a Janoshik report exists for a compound it is listed on the COA page at https://etchedresearch.com/coa/, and the report itself carries the lot number and the measured purity. Not every listing has a report posted yet, and the COA page shows which do.

Where do products ship from?

Etched ships within the United States only. There is no international shipping. Orders are fulfilled domestically from within the USA. Orders ship in plain, unmarked packaging with no indication of the contents on the outside.

Who is eligible to purchase?

Etched sells to buyers who are 21 years of age or older and who are qualified researchers, research professionals, or affiliated with a research institution, purchasing for in vitro laboratory research. Every order requires an attestation to those three points at checkout, and the order will not process without it. Research Use Only (RUO) means a product is sold only as a material for laboratory and research use. RUO compounds are not drugs, are not approved by the FDA for human consumption, and are not sold or intended for personal use. Shipping is to United States addresses only.
