Melanotan II vs Phenylpiracetam
Well Studied vs Moderate Research
monitor Mechanism-based · 51% Both Melanotan II and Phenylpiracetam can raise blood pressure. Monitor BP regularly and consider adding cardiovascular support (cardarine, telmisartan, or similar).
Molecular Data
Melanotan II Phenylpiracetam
Weight — 218.25 Da
Half-life ~2 hours ~3-5 hours
Type Synthetic alpha-MSH analog Racetam derivative (C12H14N2O2)
Key Benefits
Melanotan II
01 Rapid tanning without UV exposure
02 Enhanced sexual function and libido
03 Appetite suppression
04 Improved mood via melanocortin activation
05 Photoprotection through increased melanin
Phenylpiracetam
01 Potent cognitive enhancement including improved memory, focus, and information processing speed
02 Psychostimulant properties that increase motivation, mental energy, and alertness without the jitteriness of classical stimulants
03 Physical performance enhancement through improved stamina, reduced perception of effort, and increased exercise tolerance
04 Enhanced cold tolerance -- a unique property among nootropics, originally developed for extreme-environment performance
05 Anxiolytic effects at standard doses, reducing stress reactivity without sedation
06 Anticonvulsant activity demonstrated in preclinical models
Dosing Protocols
Melanotan II
Loading: Start 0.25mg daily, increase to 0.5-1mg; Maintenance: 0.5-1mg 2-3x weekly / Loading phase: Daily for first week, then tanning maintenance 2-3x weekly or as needed for sexual enhancement
Initial loading phase 0.25mg 1x daily
Tanning maintenance 0.5-1mg 2-3x weekly
Sexual enhancement 0.5-1mg As needed
Minimal side effects 0.1-0.25mg Every other day
Photoprotection 0.5mg 2x weekly
Phenylpiracetam
100-200 mg, 1-2x/day / Once or twice daily (morning, or morning and early afternoon)
Side Effects
Melanotan II
Nausea (pre-treatment with antiemetics recommended)
Facial flushing
Temporary blood pressure elevation
Fatigue
Spontaneous erections
Phenylpiracetam
Insomnia, particularly if taken in the afternoon or evening -- the stimulant effects can persist for several hours after dosing
Irritability and overstimulation, especially at higher doses or when combined with other stimulants
Headache, most commonly caused by increased acetylcholine demand without adequate choline supplementation
Rapid tolerance development -- the most significant practical limitation, requiring intermittent dosing schedules to maintain efficacy
Contraindications
History of melanoma or dysplastic nevi
Pregnancy or breastfeeding
Cardiovascular conditions
Uncontrolled hypertension
Known hypersensitivity to phenylpiracetam or other racetams
Severe hypertension or cardiovascular disease (due to stimulant properties)
Pregnancy and breastfeeding (insufficient safety data)
Severe hepatic or renal impairment
Competitive athletes subject to WADA testing (phenylpiracetam is a prohibited substance under Section S6: Stimulants)
