Sus was designed to be taken once a week, so you should be okay with that protocol if you only want a trt dose.
I don't really agree with your reasoning Sil.
It seems like a waste of time, money, and potentially health to half ass a cycle for 4 weeks.
If you're going to shut you HPTA down for a cycle then you should do what gets results and run 250mg twice a week for the whole cycle.
