Lol naw I wouldn't ever go that low.
Here's the way I see it, I don't believe you can clean receptors per say but I do believe that your CNS and pretty much every other cell in your body gets used to a "certain dosage"
I think there's many different ways to go about keeping cell receptors sensitive,
There's a healthy way and a few not so healthy ways, I lean more towards the healthy way,
A healthy way in my opinion would be as low dose of testosterone as you can manage without feeling like total shit and can still keep your strength and so forth.... Then run a "cycle of an androgen, a nor-19, an oral and maybe a anabolic. Test tren winstrol and maybe mast... Take equal time off, gets bloods etc... Or you could come off which I don't like that idea because if you've been on for a while you'll just feel like shit,
A not so healthy approach could be, keep test moderate to high and rotate compounds, tren then deca then an oral then whatever else, basically whatever you can get your hands on just rotate them. Don't go crazy on dosages because high doses I don't believe are necessary, there's only so much your body will handle at once. Nothing like Bostin runs just maybe 2 or 3 compound at moderate dosages and GH if you can afford. Basically just rotate compounds all year depending on your body fat and your goals,
