KPV Side Effects and Safety
Reported KPV side effects, contraindications, and safety signals.
Limited Safety Data
No formal human safety or tolerability data exists for KPV. Given its origin as an α-MSH fragment, theoretical concerns include unknown effects on appetite or mood at higher doses, though KPV specifically lacks the receptor-binding profile responsible for Melanotan II's stronger appetite/libido effects. Active CNS or psychiatric conditions and pregnancy are treated as precautionary contraindications.
Contraindications
- pregnancy
- active malignancy
- known CNS disorders without physician oversight
