This is only true if you inject the drug in high doses for performance-enhancement. The tiny quantities in Score would not have this effect.
Welcome to the forum Dr. Harry.
You are right that we can expect significant differences between injecting or eating large quantities of a substance vs. applying tiny doses to the skin. I also suspect that this is true of most perfumes. If anyone wishes to test my hypothesis by drinking or shooting up a common perfume and noting adverse health effects, I’d be much obliged. 
I’ve used the Score quite a bit now. I am convinced there is a pheromonal effect going on. My impression is that it is similar to low dose of ammo or pheroproof in effect, but less sexual. Unfortunately I don’t know the dosages used in Score.
Yeah,
Putting it on you is much different than in you. Like hair spray. Or Off Mosquito repellent.
