This stuff is extremely potent. Whoever sold it to you should've given you a good idea what dose to take. It's probably made that each spray is a dose or a fraction of a dose so you could always just do a partial spray to start and work slowly up. You can always take more, but you can't untake as there's even the possibility that narcan might not be able to knock it off the receptor. There's really not much information on this compounds use because it's so new and used mostly by people who don't discuss their use habits.
