you need to downregulate numbers of ARs , if you take tiny dose of fin, and then quit for 2 weeks, for the body it is like taking DHT. since it is the increase in DHT which will downregulate AR expression.
If people take HUGE dose of fin, DHT goes to zero. body adjusts numbers of receptors, like the cell will have instead of 10 receptor proteins , it will have 30.
then you quit fin and DHT goes up very fast. but the cell has 30 receptors now. and body cant manage fast enough to downregulate number of receptors
So it just shuts down ARs with methylation, and ARs where testosterone is DOnt work.
so now you are stuck with the same 30 overexpressed receptors and increased methylation to stop the ARs
so if you lower DHT. this will stop methylation, and then if you increase DHT gradually. slowly , constantly, this will give time for the body to downregulate NUMBER of ARS. and keep methylation put.
I guess the same thing can be done, by just killing methylation for a bit.( i was thinking about it, lets say with NIACIN)) or feeding high doses of DHT which wil overwhelm the methylation ( Cdnuts protoclol, r andro cycles)
and since methylation is not there. boom, numbers of ARs will have to downregulate. and then you quit niacin , high dose
and you are back to normal.
