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.
