PT-141
PT-141, also known as Bremelanotide, is a synthetic peptide belonging to the melanocortin receptor agonist class. It is structurally derived from melanocortin-based peptides and is designed to interact with central melanocortin receptors, particularly MC4 pathways. It is studied for its role in modulating neuroendocrine signaling and central nervous system regulatory processes. Commonly utilized in research settings to investigate melanocortin-mediated signaling mechanisms and behavioral pathway modulation. Supplied by Peptico for research-use only.

Short-Term Storage - Lyophilized Powder Form Only
- For maximum potency, lyophilized materials may generally be stored between 2°C and 8°C (36°F to 46°F) for up to 4 weeks when maintained in their original, sealed lyophilized form.
- Maintain a cool and dry environment.
- Protect from moisture and light.
- Minimize exposure to humidity and temperature fluctuations.
Long-Term Storage - Lyophilized Powder Form Only
- For maximum potency and long-term preservation, lyophilized materials may generally be stored between -20°C and -80°C (-4°F to -112°F) for up to 1 year when preserved in their original, sealed lyophilized form.
- Maintain a cool and dry environment.
- Protect from moisture and light.
- Minimize exposure to humidity and temperature fluctuations.
Important Note:
Storage guidelines apply only to lyophilized material in its original, sealed, and untampered vial.
