49er has it right--- he's just accepted what others haven't ..
This is pure speculation , but the AAS user who has experienced positive results from a cycle, both physical and mental, is now to a certain degree wanting those "feelings" all the time... He knows he shouldn't be on all the time but he really wants to be.. Maybe with "bridging" he gets to feel like he is still "on" to a certain degree and is laser focused on the next cycle so he can be on again.... Even if he is running insulin or sarms,, he is injecting and taking compounds,,,, the taking of compounds gives him a feeling of still being "on"--
This is what he is after,, always wanting to be on something. It's a mental "addiction" for the sake of "physical" performance
Nothing wrong with this IMO-- blast cruise bridge whatever,, we have that choice as free men
