Cycling M

I know “M” does not need to be cycled. However, I prefer to cycle it so that my body never becomes accustomed to it, whether in a month or two years. I am thinking about doing a five days ‘on’ and two days ‘off’ cycle. What do you guys think? Will following such a cycle permit me to use “M” for years and still be confident that it is potent when exposed to my body? Or should I just take it every day and maybe after every six weeks take a week off? Thanks T-Buddies!
