Hi, Pheropimp. Thanks for your question, and welcome to the forum!
Instant Jerk is a novelty, “fantasy fulfillment” product. It can be fun, but it’s not what I’d personally use for daily wear. 
Jerk is high androstenone with several intensifiers. Total pheromone content is currently 17.5mcg per spray. 12.5mcg of that is androstenone.
Instant Jerk also includes a small amount of female copulins (compounds that women excrete during sex), that act to boost your own assertiveness and provide a form of social proof to those around you. It says loud and proud: “I’m the strong, aggressive bad boy… and yeah, you can smell the sex on me. Would do you expect? The ladies can’t resist a jerk!”
Raw Power on the other hand, is a much more “reasonabe” product. Some people who respond well to androstenone may even be able to use it daily.
Raw Power is androstenone only, with a small amount of diffusion enhancers added. It’s intended as an upgraded replacement for Primal Instinct. Raw Power is fully dosed, has an easily mixable oil carrier, and has enhanced diffusion characteristics over typical oil based products.
It comes with a nice rubber and glass dropper top for controlled application. With it, there’s no worries about accidentally putting on too many drops. You can put the exact number of drops you want, exactly where you want them.
Many people complain that even 1 drop of Primal can cause an “androstenone OD”. That’s been fixed with Raw Power. You get 10mcg of androstenone per drop, 5700mcg total content (700 more than Primal) in 15ml (a half an ounce).
