Mixing MDMA (molly) and Xylazine (tranq)
Caution
The stimulant hides how sedated you are, and the sedation takes over as it wears off, while the heart is pulled both ways.
Don't redose on the stimulant's say-so, and never use alone.
What “Caution” means
Carries risk that is worth understanding before combining. Reduce doses and do not use alone.
How the ratings workThe longer explanation
The stimulant hides how sedated you are, so the sedation gets underestimated and the opioid redosed, and what is left of the xylazine — and of the fentanyl it nearly always comes with — takes over as the stimulant fades. Xylazine also slows the heart and drops blood pressure while stimulants push both up: hard, unpredictable strain on the heart.
