PT-141

PT-141 10ml Vial

The Science, Simplified:

      PT-141 is a synthetic cyclic heptapeptide analog of α-melanocyte-stimulating hormone (α-MSH). It selectively activates melanocortin receptors in the hypothalamus — the command center for sexual desire and behavior.

Product Specifications – PT-141 10mL Vial (20mg)

• Total PT-141: 20 mg
• Volume: 10 mL vial
• Concentration: 2 mg/mL
• Purity: Research-grade, third-party tested (COA available)
• Format: Ready-to-use liquid vial

Key Research Focus: Sexual desire, arousal, and performance enhancement via central melanocortin receptor activation.

Physical Form & Solubility:

• Appearance: White to off-white lyophilized powder
• Solubility:
  • Water: Highly soluble (≥50–100 mg/mL reported for acetate salt; freely soluble noted in technical sheets)
  • DMSO: ≥100 mg/mL
  • Ethanol: Soluble
• Often handled and supplied as the acetate salt (C₅₂H₇₂N₁₄O₁₂, MW ~1085 Da) for improved stability and solubility in research settings.

Stability & Handling Notes:

• Lyophilized powder: Stable long-term at –20°C (typically 1–2 years when protected from moisture and light). Some suppliers list ≥2 years stability.
• In solution: Sensitive to heat, light, and pH extremes. Peptide bond hydrolysis can occur; reconstituted solutions are generally kept refrigerated (2–8°C) and used promptly (weeks-scale stability in research protocols).
• Protect from moisture during storage/handling to prevent degradation.
