Paxil - Opinions?

I have been reading a lot of different opinions and forums about SSRI drugs and bodybuilding. I am wondering if the drug Paxil has a correlation or impact on whether one makes as significant gains or if one can still be “successful” on this drug. I have been aware of the weight gain side effect but in reality I’ve only seen the horror stories where individuals are gaining 50 pounds… but in reality what is common? I have also heard things about SSRI lowering testosterone and such. I am confused on what to think or beleive and have been medicated for anxiety for many years.
