Yes, and involved slightly
Is the RP lab or commercial grade?
Technical, close to 99% pure powdered
What are the laws governing the sale/possesion of RP in your area?
Canada. It just got added to the restricted list Jan1, although there in no agency in place to inforce it.. yet. The transfers would be imported through customs with the risk of detection and loss.
