Query: Miracle Working Energy Pills

Ok, no joke, these things are better than any other Vit B complex vit out there. I swear, i have tried others bc these are hard to find. I ran across these a long time ago in some vitamin shop in San Francisco and have never been able to find them any of the shops where i now live. Anyway, I am not sure if it is the dose or combo of the Bs with it but they give me real energy. I have tried 4 other brands and none of them do a thing for me. This is the only one that really works.
