PT-141
PT-141 (Bremelanotide) is a synthetic cyclic heptapeptide analog of α-melanocyte-stimulating hormone (α-MSH) engineered to selectively activate melanocortin receptors MC3R and MC4R. This cyclic structure is studied in laboratory models for its potential roles in central nervous system signaling, sexual function modulation, and neuroendocrine pathway research. Characterized by its defined amino-acid sequence and high receptor affinity, PT-141 is widely referenced in scientific literature for peptide structure–function analysis, receptor pharmacology, and investigations into appetite regulation and sexual arousal mechanisms.
Researchers value PT-141 for its ability to induce targeted melanocortin signaling in the hypothalamus and limbic system without the peripheral pigmentation effects of related analogs. Its cyclic heptapeptide design provides enhanced metabolic stability for long-term in-vitro and ex-vivo studies of sexual behavior, erectile function, and libido pathways in controlled experimental settings.
Ceritide Research offers PT-141 as a premium 10mg lyophilized research peptide with verified ≥99% purity confirmed by independent HPLC and mass spectrometry. Supplied in a sterile vial and ready for immediate reconstitution per your protocol, this product delivers the reliability top research labs demand.

Peptide Storage Guidelines: Best Practices for Research Stability
At Ceritide Research, we provide high-purity peptides for laboratory and scientific research. Proper storage preserves peptide integrity and supports reliable experimental results.
Storage Guidelines for Lyophilized (Powder) Peptides
- Long-Term Storage: Keep at -20°C (-4°F) or lower (ideally -80°C / -112°F) for multi-year stability.
- Short-Term Storage: Refrigerate at 2–8°C (36–46°F) for weeks to a few months. Minimize room temperature exposure.
- Best Practices: Store in airtight vials with desiccants. Allow vials to reach room temperature in a desiccator before opening. Protect from light and moisture. Aliquot to reduce freeze-thaw cycles.
Storage Guidelines for Reconstituted Peptide Solutions
Once dissolved, peptides are less stable and should be used promptly:
- Recommended Temperature: Store at 2–8°C (36–46°F) (refrigerator) for short-term use, typically up to 1–4 weeks depending on the sequence and buffer.
- Longer-Term Solution Storage: Aliquot and freeze at -20°C (-4°F) or lower. Avoid storing solutions long-term when possible.
- Best Practices: Use sterile techniques, bacteriostatic water or research-grade buffers, and minimize exposure to air and light. Prevent repeated freeze-thaw cycles.
