I'm not American... Really I agree on not getting into a debate about that however, this forum is not for that.
I stand by my case, proper use of NLP requires social skills. It's not just a manuscript you could read from a paper and then suddenly the girl is all over you. Body language, voice tonality, confidence, charming vibe are just as important as in any other aspect of the game, because if the girl does not fully commit her attention to you, you can go OMS on her all night long and it will have absolutely no effect.
Rape is fucking a girl without her consent as far as I know.
When I have built enough attraction and comfort I use NLP in the seduction phase. I will tell her that if she is willing to proceed I can put her into a relaxed state of trance and I can make her experience a variety of emotions which will make her so aroused that she will be soaking wet by the time I finish. If I have done the first two stages correctly, I have yet to find a girl who declined it. I also have never got a buyer's remorse of how I used her as a tool and they don't run a mile away. It's nothing magical. It's just a great way to get emotional effects out of her. Which is the basic of most of the pick-up methods as far as I know.
Back to steroids. If you just read up on NLP and think you know it all without lots of practise it will be just as useless as steroids without workout. And you haven't mentioned the biggest and probably most important, and most dangerous effect of steroids, if we really want to get into its physiology, that it turns off defensive mechanisms(namely tiredness) of the muscle, so the user will be able to perform above his strength, meanwhile he is more prone to injuries and can easily be left with torn muscles.
Steroids are unlike NLP because NLP will not backfire IF you use it properly and within morals. Steroids will kill your immune system(White blood cells have steroid receptors and it causes a deactivation signal), your kidneys(can't process the too much protein which are used to maximize muscle gain, results in proteinuria and in severe cases can cause kidney failure), I will not list all of the effects, but it will damage the cardiovascular system, the liver, the reproductive organs, and minorly it can harm the CNS too. Drawbacks outweigh benefits. With NLP the only drawback is that it CAN be misused for immoral purposes. (So is this with the other methods btw. I can pick-up a chick with Gambler's Stealth Attraction, and then proceed to cheat on her with all of her friends. Or... I can use NLP to seduce a girl, and then stay faithful to her... which is btw the case with my soon 1 year long relationship. Which is worse morally?)
If you were already good with women, why use NLP
I thought this is a forum where we are looking for not just being good, but to excell with women. You can always be better. NLP is not a magic pill like they think it is. It's just as much hard work as any other method. But it has other benefits too. You can manipulate your own feelings, your own perception of the world, get yourself into resourceful states for any task you have to accomplish. I also have a better understanding of how human emotions work since I started using it. And I repeat, I always use it to GIVE something, not to make someone my property, or to get someone do something for me. That is out of my morals regardless of the used method.
