PT-141 (Bremelanotide)

A melanocortin-pathway peptide studied in neurobehavioral research.

Half-life
~2-3 hours
Routes
subcutaneous, intranasal

Overview

PT-141, also known as Bremelanotide, is a synthetic peptide studied in research literature for its interactions with melanocortin receptors in the central nervous system. It is a commonly referenced compound in neurobehavioral and melanocortin-pathway research contexts.

Referenced research ranges

0.52 mg, as referenced in research, not daily — research protocols reference intermittent, event-based administration

Reconstitution default

10 mg in 2 mL yields 5 mg/mL; a 1 mg reference dose is 0.2 mL (20 units on a U-100 syringe).

Storage

Store lyophilized vials in a cool, dark place; refrigerate after reconstitution and protect from light.

Considerations

  • Interacts with central melanocortin receptors rather than a peripheral tissue target.
  • Research protocols reference intermittent rather than continuous administration.
  • Reconstituted peptide is temperature-sensitive and light-sensitive.
