as above stated. risks are very different from two different compounds that works totally different.. mdma is a very safe drug to use hence you use it properly and using it properly is something many people cant seem to do(including myself earlier in my life) how to use it safe is esay, this is my personal "safe" opinions they may not be another mans opinion but it's importnant to space out, 90days is good so u let ur serotonin replenish and be replenished for a while. never ever re-dose, ever. ur first dose id say 2mg/kg is the initial and only dose needed, for me redosing has never increased roll-time strange isnt it? ive taken timer on same batches. but something that increase rolltime and increase intensity is weed, so i always smoke alot of hash during my rolls. to be safe also eat after roll. no need for 5htp and other stuffs day after, i just workout, eat and sleep well til next roll. this way im all fine up in my headoffice but i once rolled 3times a month and realized that mdma has a dark side it lead to 2week depression i rode it and after that i had massive respect for mdma i only use it twice a year now perfectly fine.
so my most importnant stone is - unless u have heart conditions, it is to let serotonin replenish and let it be replenished for a while before deplete it all.. havin 8month long depression from bein a dick using mdma too much is not worth the kick u get from mdma. its a rather short experience tbh.
