Very good questions, we need to keep this thread going.
I think LilPyschotic has a good start on this.
Thoughts
We use SERMs for two reasons:
1) Kickstarting our test production after a cycle
2) Keeping gyno away
Now, #1 is great for immediately after post cycle therapy. We want to keep our gains as well as get our bodies test working again.
The problem is, once our test is up and running, we're continuing to run a SERM. I beleive this is acting like a natural test booster, forcing our bodies to produce more test.
While this is all well and good because a SERM will block the ER from forming gyno, once we stop dosing the SERM there will be a higher level of test, and therefor a higher level of estrogen which could trigger a rebound.
It also doesn't help that SERMs increase ERs.
Possible Solutions
I have been saying this for a while, about Epistane and SERMs as well.
More is not better.
Have you ever noticed that studies on gynecomastia, breast cancer, etc, have not gone over 20mg?
I think the possible solution lies in how alot of us are ending our post cycle therapy's on 20mg of Tamoxifen, for example. Alot of studies into treatment of gyno with Tamoxifen have been at 10-20mg.
Could the possible solution be that we're going too high in our doses? And whats happening is its leaving our body in a state of high test: high estrogen ratio? Maybe doing 40mg the first few days of post cycle therapy, and then going down to 20mg or lower for the rest of the PCT.
Personally I have always beleived in doing a strong taper to end a post cycle therapy, going down to as low as 10mg of tamoxifen for the last week.

Better than yesterday
Thats just one of the many post by people on this site talking about SERMs increasing ERs.. They are not told to stop taking Prohormones. Dude I will just be honest with you.. I am 5'11 225lbs.. 8% body fat. My bench is 4 sets of 10 at 325.. chances are I have the stronger body.. I might not be the brightest person there is, but I am here to learn.. not to be mocked at like a stupid person when I am trying to learn. I dont tell weak people to leave the gym. I see many weak people at the gym, and I tell them to never give up. You would not dare talk to me like that in person... your lucky its a computer... On another note I ask alot of ????.. If you dont want to take the time to answer them with a kind heart.. then shut your pie hole. The day I become insulted in stop asking questons.. no matter how stupid they may be to you.. is the day I will not learn a thing. So after saying that.. if anyone would like to tell me there take on the serms making more estro recepters.. and if we keep them.. Let me know something.
