I keep seeing people swear by pulsing Anadrol because it supposedly “resets receptor sensitivity” after it stops working. I finally dug into the actual studies and that claim looks pretty weak.
First off, Anadrol has notoriously low direct binding affinity to the androgen receptor. That’s been known forever. Check the 1984 Saartok study. Yet it still kicks ass for mass and strength. It works through strong downstream AR signaling and protein synthesis. Low binding doesn’t automatically mean it “desensitizes” your receptors in 2 weeks.
More importantly, AAS in general tend to upregulate androgen receptors in muscle, not downregulate them. A 2022 review in Muscles peer reviewed scientific journal went over this and said the whole “chronic AAS causes receptor burnout” idea is flawed. You actually get more receptors and better response with continued use, not less.
Clinical trials back this up too. They’ve run anadrol continuously for 12–32+ weeks in patients and kept seeing lean mass and strength gains without any need to pulse for a “reset.” Gains slow down eventually because of sides, not because your receptors magically stop listening after 14 days.
So yeah, pulsing can still be useful for giving your liver and blood pressure a break if you want to run Anadrol longer overall. That part makes sense. But the idea that it magically resets sensitivity and makes each blast hit like the first one? That’s pretty much a myth that has been spreading around on this forum. What do you guys think?
