Propylhexedrine w/ opiates for comedown?

[Siccness909]

I haven't dosed my 250mg cotton rod yet, but when the inevitable crash comes (which I've experienced...HORRIBLE IMO) would some opiates be safe to dose to relieve crash? I know with most stimulants its safe and highly recommended but just to make sure outta HR I wanted to ask with this specific stimulant. Anyways thanks in advance as always guys!
