Can You Take Armodafinil and Phenylpiracetam Together?

Use extra care with this pair

The short answer

Armodafinil is the R-enantiomer of modafinil with potent wakefulness-promoting effects. Phenylpiracetam also has significant stimulant properties. Combining two potent stimulant nootropics risks excessive CNS excitation, anxiety, and cardiovascular stress.

How to arrange timing

Avoid combining. If both are used, take on alternate days and monitor heart rate and blood pressure.

Reference

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.
