Best way to cycle these nootropics?

Hi. I have used nootropics for a few months now but I could really use some guidance which would be greatly appreciated :) I use: Oxiracetam, Piracetam, Aniracetam, Pramiracetam and Noopept. I was thinking as a cycle to take Piracetam, Aniracetam and Pramiracetam 3 days a week every other day and also Noopept and Oxiracetam 3 days a week every other day. Would this be a good cycle shedule? I'm looking to keep the tolerance down but at the same time i want to keep the potency of each nootropic as high as possible as I have heard some nootropics need to be used every day? Any help or methods again would be greatly appreciated.. Thanks!
