Not sure why you wouldn't just order some kind of vaporizer setup for your CBD. Would hit you just as quick as IV and bioavailability is gonna be a lot better than oral.
Injecting stuff can feel "hardcore" but it so much riskier than any other means of delivery. Why take that risk for CBD of all things
No IV injection, just subq. IV is where I draw the line.
It's no more risky than anything people inject on this board. It filter sterilized just fine and stayed in solution.
You're right; vaporization/combustion will produce better bioavailability than oral, but for some inhalation is not preferred.
