I've done this twice, both times with a month+ break on MDxx.
First of all, I had an amazing time both times!
The first time I took 2x 100mic needlepoint tabs and 175mg of tested MDA. The second time I took 1x 200mic needlepoint tab and 200mg of tested MDA from the same batch.
I took the MDA 3 hours after eating the tabs the first time. I changed that to 2.5 hours on the second time which I liked more.
Peaking the second time was extremely intense with crazy visuals, eye wiggles, euphoria, empathy, speedy enough to dance like crazy. Needless To say, both times were beyond mezmorizing and I highly recommend this combo. Just stay hydrated and you'll be fine! I find this combo perfect for festivals/long shows as both drugs last 6+ hours on their own.
