Ive had the most luck using a spoon pipe from that very site. A pinch of peppermint, melt the dmt ontop of the peppermint, then toke long and slow.
I can clear 40mg in one hit, put the pipe down then have a break through.
I seriously recommend the spoon pipes. Clear ones are best, you can toke REALLY gently till it starts to cream up then start toking long and steady, deep and slow.
40mg in one toke... bic lighter.. works every time.
