About PT-141 (Bremelanotide)

PT-141, also known as Bremelanotide, is a synthetic peptide analog of alpha-MSH (alpha-melanocyte stimulating hormone). It's a melanocortin receptor agonist that has been researched for various personal health applications.

Typical Research Dosing

  • Starting Dose: 1000mcg (1mg)
  • Standard Dose: 1750mcg (1.75mg)
  • Maximum Research Dose: 2000mcg (2mg)
  • Timing: 30-45 minutes before desired effect
  • Frequency: As needed, not daily

Reconstitution for 10mg Vial

2ml Bacteriostatic Water

Concentration: 5mg/ml
1000mcg dose = 20 units
1750mcg dose = 35 units
2000mcg dose = 40 units

1ml Bacteriostatic Water

Concentration: 10mg/ml
1000mcg dose = 10 units
1750mcg dose = 17.5 units
2000mcg dose = 20 units

Administration Notes

  • ✓ Subcutaneous injection (most common)
  • ✓ Common injection sites: abdomen, thigh
  • ✓ Effects typically begin 30-45 minutes post-injection
  • ✓ Peak effects at 2-3 hours
  • ✓ Duration: 6-12 hours

Research Considerations

Common Research Observations:

  • • Onset time varies between subjects (30-90 minutes)
  • • Some subjects report mild nausea initially
  • • Flushing may occur in some research subjects
  • • Effects may be more pronounced in female subjects
  • • Tolerance does not typically develop with intermittent use

Storage & Stability

  • ✓ Lyophilized powder: Store at 2-8°C (refrigerated)
  • ✓ Can be stored at room temperature for short periods
  • ✓ Reconstituted solution: Refrigerate at 2-8°C
  • ✓ Use within 30 days of reconstitution
  • ✓ Protect from light

PT-141 vs MT-2

PT-141: More selective melanocortin receptor activation. Does not cause tanning. Faster onset, shorter duration.

Melanotan II (MT-2): Broader melanocortin receptor activation. Causes tanning as side effect. Slower onset, longer duration.
