It could work but why would you do it that way ? I think you would get far better results from 500mg/week for 10 weeks as opposed to a lower dose for a longer time. Is there any particular reason behind you wanting to do it this way ?
250mg Im weekly is a maintenance dose..you won't get big, but you will keep your bodyfat down, your insulin resistence in check, and you'll feel pretty good..BUT YOU WON'T GET BIG.
If you shut down your hpta axis for that long, it's is NO GOOD for your body. It will just cause problems down the road. The best way to do a cycle IMO, is to get in and get out, and take a long break.
