I haven’t had a chance to test my P83 as extensively as I’d want yet, but I agree with the OP that I don’t notice anything about it as a standalone product. All I know is that at 1-2 sprays (10-20 Mcg), it makes Ammo a alot more effective. I don’t really use it with anything else, but I find that those two complement each other really well. They really should make an Ammo test pack with some P83 in it, I bet that would be killer.
