In reality, you should be able to add an extra 20lbs in a month without anything but a good workout rutine. An extra 5 lbs per week on the bench is pretty average. If you don't normally do that much, then I would think most of it was just psychological.

That's why they have double blind studies in research. To counter the psychological effects. The administrator knowing that you are getting the real thing or just a fake can play a psychological factor without even knowing it conciously.
