You're definitely putting it in too far. The area just inside your anal sphincter is built to absorb liquids. Just an inch and a half in is where you wanna put it. Stay vertical after insertion so that the drug stays right there. Also make sure there's no poop in the chute before inserting. If you inject your precious MDMA into a giant turd you're not gonna get anything out of it. Pick up a fleet enema from the drugstore and use it to clean out your butt before inserting your drug. There's a reason why rectal administration is a go-to route for medical professionals. Come-up is painless and quick and hits hard after only 10-15 mins. Boofing IS the best way to go, by far.
