I'm pretty sure this product is in the "gray market" at best. Selling 4-aco-dmt for human consumption would seem to violate the Analogue Act and thus be felony in USA. I'm sure there are plenty of noncriminal violations regarding supplement labeling there too

This is part of a proud American tradition. “Pills from the gas station that might kill you” is a staple in all 50 states. For example tianeptine, spice/k2, mystery erectile pills, bath salts, now 4-aco-dmt etc.
