Hey there, welcome.

Hope you stick around.
That's odd, for freebase AMT that should be a nice, full dose. AMT does smell DMT-like except to me much more like a chemical fertilizer, it's about the worst smelling drug I've ever smelled, whereas DMT is kind of pleasant in a weird way. Since it's yellowish I suspect a slight amount of degradation, but I've had brown freebase that still worked before (just not as strong).
You shouldn't have had THAT much tolerance from 1p-LSD a week before.
I've had underwhelming experiences with AMT but pretty much only when I dosed too low or
Does it smell really strong or just a little? Freebase AMT should smell absolutely rank, like it brings tears to my eyes. The AMT that was going around for the last couple of years that I was aware of was the succinate salt, it smells only a bit and it's only 60% as potent so you need a higher dose. If you mix a little in water does it dissolve? if so it's not freebase.
