PT-141 (bremelanotide) is a melanocortin receptor agonist (MC3R/MC4R) that works centrally—not like Viagra. It's FDA-approved for HSDD in women, but remains a hot research topic for other applications. When sourcing PT-141 for research, look for: ✅ 99%+ purity – verified via HPLC ✅Third-party COAs– batch-specific, not generic ✅Lyophilized powder– stored properly (< -18°C) ✅Clear "for research only" labeling– non-negotiable Price range: ~$35–$60 for 10mg | ~$105–$180 for 50mg Common documented effects: nausea, flushing, headache, transient BP changes.
