When it comes to gyno prevention or treatment ralox is king by far. Its binding affinity to the e2 receptor in breast tissue is stronger than any other serm. Also you dont need to look for logs - you can look for real medical studies as it is proven to be the most effective at gyno treatment and reversal even including pubertal gyno. So anecdotal broscience isnt needed - it has real science backing its use.
As far as pct it (ralox) does not stim the production of LH like tamox , clomid or torem. Toremifene is pretty close to tamox when it comes to induction of LH production and it has an amazing safety profile. That being said I rely on tamox and clomid. If, however, one of those 2 caused me unmanageable sides I would in no way hesitate to replace the offending serm with torem in my pct protocol.
