I decided to take the yellow pill.. Lets hope I don't end up dead.
I looked to see which one best fit what I was looking for and the single marquis tested for all that I would want to know. I used to get some real good "triple stacks" that were loaded with amp and mdma and loved them, but this stuff, idk... All the others have checked out on my search. the yellow doesn't exist. So at least I may not have a headache or there is some other shit in it. We shall see in about an hour.Marquis will tell you if it's MDxx. You need the Simon's reagent to know if it's a primary or secondary amine (MDA vs MDMA or MDEA, due to teh rarity of MDEA you can assume a compound testing for MDxx and a secondary amine is probably MDMA).
My experience is larger pills are usually not as good but people love their triple stacks. It's just more binders kiddies.
