Lol,you need to sweet spot test all of them.Ammo and A314 are the more important ones to find it though.With the socials,you can go pretty high before seeing any overdose.The 1.29A is a bit stronger than the B one and yeah you can get double strength if it happens to be 2 or 4 sprays.Not sure about copulins,havent tried them.Usually used by the women more because natural copulins are produced by the female vagina so not usually naturally on a man unless its after sex.Can ask around in the mens or womens board for more info.Check out the link below for how to sweet spot test.
