I'm sorry if this runs afoul of the sourcing rule. I got the impression online that αMT is fairly common, but I made an honest effort to search through all of the DNMs immediately available to me and I only found one vendor with almost no feedback selling it at a suspiciously low price (~$20/1 gram). I hope mods will be understanding of my request for αMT sources. I wasn't being remiss on my end.
I'm sure this will not get deleted as it is a rare product inquiry.
