I know that it's a great opiate potentiator. Any way to safely IV it? I'm wondering if you can get the liquid for IV over the counter? if not, is there a way to safely inject in a rig without all the binders and fillers?
You can get liquid Benadryl (in cough syrup type preparation) but it will have a ton of sugar and shit in it you will need to filter out. But I do know for sure that you can buy single-ingredient, Diphenhydramine syrup OTC.
I would cation against doing this, if you take your Benedryl 1 hour before you shoot up you should get all potentiation you need. Trying to filter a syrup sounds extremely dangerous, although you might be able to use the capsules with powder in them, dissolve, cotton, etc. Still, too much diphen to fast may give you the opposite of the desired effect. I once snorted a Benedryl hoping that I would get to sleep faster, instead I was hyper as hell and miserable for 2 hours.
