so other than the list on the first page, are there any other good recommendations to take? going to stock up full of supplements, thanks in advance!
I really wouldn't recommend "stocking up full" on supplements personally.
Piracetam + a choline agent if you need it is a *very* interesting supplement for MDMA and related, but not really for "harm protection". Instead it "enhances" the roll for many (myself included). Effects are *very* variable, but IMHO it's worth a try, both for the potentiation and the overall "brain energy boost" (some get it, some don't...).
I've never tried magnesium, but I've heard others say that it indeed does reduce jaw clenching.
Green tea, whether extract or (better) by the cup, is probably a very good one to play "clean up crew" (anti-oxidant) after the experience. R-ALA might also be interesting in this regard, but green tea has way more tradition and studies behind it.
Melatonin will help calm down; it's a better sleep aid than the shitty histamines sold OTC.
The rest of the list? I dunno. I really don't know any supplement that will protect you from the temporary downregulation of MDMA, or help you much afterwards.
I guess I could say some supplements for general exercise aid and well being, because a healthy body will help the experience overall. Aside from piracetam and green tea (along with various other foods), most of my supps are to "enhance" exercise (creatine, beta-alanine, taurine, and the "experiment" forskolin) or act as an insurance policy (multivitamin; fish oil may be worth a try if you don't eat a lot of creatures of the sea). These are supplements, not the foundation. The foundation is eating right and exercising.
