Well first; a pill to help you with finances and success? Can anyone seriously believe that such a thing exists?
Two; if you know it is a placebo it can't help you since the placebo effect depends entirely on the person taking it not knowing.
So as others have already said the best you can hope for is an acute "cashendectony" (the removal of cash) which is pretty much the opposite of what you are looking for.
If it is any help, by taking them you are helping the seller realize success.
