You are completely right. I guess we just have to try it out ourselves. Now im trying to choose my last shot. Either TRT or Progesterone, if i can decide which one upregulates the AR’s on prostate.
Here is a messsage i got from a pharmacologist and a bodybuilder who studies medicine and knows a lot of good information.
Upregulation through antagonists is a common phenomenon but with nuclear receptors I wouldnt be surprised if it can differ from receptor to receptor. I don’t see evidence of direct antagonism from progesterone. Could be a downstream effect. Not sure though.
