5-MeO-xxT + Advil PM (Ibuprofen)Low risk, no synergy
Neither substance is expected to meaningfully change the other. Both still carry their own individual risks.
No specific interaction is documented. Ibuprofen's standing risks — stomach bleeding and reduced kidney blood flow — apply in any combination, and matter most when dehydrated, not eating, or dosing repeatedly over a long session.
