Here’s a nice post by steve on sweet spot testing :
How to find your sweet spot… - PheroTalk Pheromone Research Forum
Unfortunately mones are one of those things where more is not necessarily better. It may be a bit tricky especially at the start to find out exactly how much u need, before it becomes counter productive. Socials in general are quite safe and quite hard to overdose.
IS gives people a happy feeling so you will notice its a base for a lot of combos since happiness is always welcome. IG provides a status kind of appeal, sort of like a cool suave laid back but in charge kind of fellah - a respectable reliable man. Ammo does provide some status appeal but with a nice touch of sexual tones. Ammo is also nicely buffered so you are LESS (but not impossible) likely to OD. So please please please do not purchase a double strength ammo at the start before figuring out how much your body can take.
Take the time to do sweet spot testing and slowly figure out how each product works for you to get the most gains out of it
