Can You Take Melanotan II and PT-141 (Bremelanotide) Together?

Use extra care with this pair

The short answer

Melanotan II and PT-141 (Bremelanotide) both activate melanocortin receptors (MC3R/MC4R). PT-141 is derived from Melanotan II. Combining them stacks melanocortin receptor activation, risking nausea, flushing, and cardiovascular side effects.

How to arrange timing

Do not combine Melanotan II and PT-141 as they activate the same receptors. Choose one based on your therapeutic goal.

Important context

Whether supplements suit you together also depends on dose, product formulation, health conditions, and medication use. Ask a doctor or pharmacist first if you take medication, are pregnant or breastfeeding, or have a chronic condition.
