Low dose Dbol on pct to keep gains? Sounds fishy

I just watched a video that was talking about this theory. Wondering if it's true. They said your body accesses your hormone levels at night while sleeping and that's when it determines whether to make more natural test if levels are low, or shut down natural test if levels are high. This theory they put forth says that since the half life of Dbol is so short, if you take a low dose of 10mg Dbol in the morning during pct it will keep you anabolic through most of the day and therefore able to keep gains made on the cycle that just ended. Then at night when sleeping the Dbol is out of your system so your body will restart natural test production.
Anybody know if this is true?
