I’d agree with you, but this is a distinctive solvent smell that disappears after letting it dry by itself or washing it with a more volatile solvent, so I’m pretty sure that this is the issue here. Also, none of the other fluorinated amphetamines (including 2-FA) have such a smell. Even worse, I’ve had batches of 2-FMA that did not carry this smell.
so yeah, it’s definitely solvent (though I can’t recognize it by smell, but Ive worked enough in a lab to recognize that this is not the smell 2-fma should emit). As a said, it’s not much of an issue, except that none of the other chems from LL have the same issue. Maybe there’s a reason for it (other than to increase weight to increase benefits), or you know, maybe I’m wrong.
However you’re right, the most logical cause for this would just be sloppy quality control, except it has been like this for at least a year now, so several batches went by.
