I recently purchased some from amazon and I am not feeling any of the effects that people talk about. I have applied it to the proper areas using the proper technique (bathing then applying to upper torso, 5 pumps) but I have yet to feel anything. I have read many posts about people applying and feeling energy,focus within a hour or two ...I am going on 6 days,nada. My wife is also trying it and she is not getting anything either. Are there alot of fakes out there???? What do you guys recommend in the Derma topical category ....Thanks !!!!!!
