I have tried it and yes! It does work for some hours but, you said you are "planning" to take it responsibly, that in my experience, is something no one can commit too, it turns out to be hard to space out the dosis MDMA feels good , then it depletes you neurotransmitters.
In short words, it does feel good but I was not able to keep it for longer than a 3 month period "responsibly" , I have had addiction before and I rather quit before it became a big problem plus I didn't got better.
After you have and take your experience with MDMA, if you feel like trying something else no matter the damage to you, try a dose of Testosterone and Dianabol , for 2 weeks or 3. This "treatment" supervised by medical exams and a doctor has given me 8 full months of recovery. And I'm okay, plus I have reduced my dianabol intake a lot in the last two months and I'm still fine. In the last two months i have only taken like dianabol 15 pills. Dianabol it's a feel good steroid or something like it.
This is my experience, probably only works for me?
