PT-141 reconstitution calculator

The research material PT-141 is available in lyophilized form in 10 mg vials. The published research record, which aligns with the approved bremelanotide (Vyleesi) framework, documents a per-use protocol of 1500–2000 mcg, with 250 mcg titration steps, administered as needed. The record specifies a single dose per administration, with at least 24 hours between doses.

This tool calculates the peptide concentration after reconstitution and the exact volume to draw for a target dose between 1500 and 2000 mcg. It provides results in milliliters and syringe units, includes precision guidance, and notes the evidence grade on file protocol is A, as it is based on the approved on-demand dosing window.
