I doubt it. It hasn't been perfect, but it's such a big difference that I know that for me it's not a placebo effect. Supposedly you don't feel a difference right away, but some people do. So, I wasn't expecting to feel any different, but was better within days. I didn't convince myself of that. There are plenty of studies that prove that they work otherwise they wouldn't exist because if it was all placebo effect that would meant that they don't work and the FDA wouldn't have approved them.
