Get one of those nasal snifters (containing nasal decongestant) that eject a fine mist when you press the lever down. Then empty the decongestant into the sink, rinse well, mix some peevee with water (strength will depend on how light or potent you want each blast to be), fill the snifter with the fluid, screw on the lid. Simple.Would you care to elaborate a bit? Mostly I'd like to know how much water to MDPV, how long did you store it that way, and did you notice any of the moisture driven degradation as far as effects when? If so, when did you notice it change in potency?
I've been wanting to mix it into some Saline spray I have, but apparently it degrades in water very fast and I hate to be wasteful.
Doesn't degrade that fast, but if you're saving it awhile, refrigerate it and use distilled water instead of tap water. And don't make really large batches at once.
