Nobody is using it as a plant feeder and it's use truly isn't intended for that either. 'Plant feeder' describes a wide assortment of chemicals and requires labeling about it's toxicity so alternative use of the chemical isn't as much of a concern to anyone as passing it off as a new OTC stimulant (which it's just a cocaine analogue). There is a large amount of research being done with similar chemicals for treatment of things like PTSD in shell-shocked soldiers (MDMA, methylone, mephedrone).

In any other form this chemical may end up scheduled and therefore useless to researchers. Though, because it is labeled as a plant feeder this makes it available to any consumer in any amount.

Don't be ignorant about something you're not familiar with.
