MDMA and Viagra (sildenafil)
Blood-pressure interaction.
Why this happens
A common combo with real cardiovascular interactions - both affect blood pressure. Riskier for anyone with heart concerns.
What this means in practice
Not among the most dangerous mixes, but it stacks risks. Keep doses low, stay cool and hydrated, and keep checking in on how you feel.
Information, not medical advice. Threshold does not promote or encourage MDMA use. This exists so that people who make their own choices can make safer, better-informed ones. It is not a substitute for professional care.
