PT-141 20mg Pen

PT-141 (bremelanotide) is a synthetic cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone (α-MSH). It binds multiple melanocortin receptors with a particular research focus on MC4R, a receptor expressed in central nervous system regions involved in neuropeptide signaling. Published research on PT-141 / bremelanotide includes Phase 3 clinical work that supported approval of the compound under a licensed pharmaceutical brand for a specific human-use indication, and the compound is widely studied as a melanocortin agonist in central nervous system pathway research.

The ProPeptide 20mg pen is a pre-filled FlexiPen device with a 20mg / 3mL label claim, ready to use out of the box. No reconstitution, no bacteriostatic water, no syringes to draw. The printed click guide is based on that label claim and ranges from a nominal 1mg setting (15 clicks) to a nominal 5mg setting (75 clicks). The box includes 10 pen needles.

Published Janoshik testing for batch PT20P-001 reports 6.84mg/ml PT-141 concentration and 99.703% peptide purity by HPLC. The purity assessment includes peptide peaks only. The report does not establish molecular identity by LC-MS or confirm whether the peptide is free base or acetate. It links directly to this product from the batch-specific Testing page. The product is not a licensed medicine and is sold as a research peptide.

PT-141 is widely cited in the published melanocortin literature. The pathway work below is drawn from that research and is described in third-person, hedged terms. Several pathways come up repeatedly:

Melanocortin receptor binding

Binds the melanocortin receptor family with a particular focus on MC4R. Acts as an agonist at multiple receptor subtypes in the published research.

MC4R pathway

MC4R is expressed in central nervous system regions involved in neuropeptide signaling. PT-141 is widely cited in MC4R-focused research.

Cyclic α-MSH analog

Cyclization of the heptapeptide stabilizes the active conformation and improves pharmacokinetic properties compared with the linear α-MSH parent peptide.
