Retrospective question about finasteride

Hi guys,

I’m currently doing a little retrospective about finasteride it’s effect it has on me.

At first 6 months of the treatment, I was feeling better and ripped a lot of body fats and actually gaining muscle. (Going at the gym 5x week).

Then after a year of treatment, I start to experience soft erection and I was wondering if finasteride was not the culprit.

I decide after a month to stop the drugs and this is where the real problem starts, no libido, fat gain, anorgasmia, impotence. It last for a good 2 years and then improved slowly. I would say I’m back at 70-80% now. r

My question is how such drugs could have these contradictory effects from 6 months to another and even I get really worst while not on it but off it.

My best friend takes it and has 0 problems… how it could affect some and some other not.

Sometimes I just thinking of dropping a pill to see if it improve my current states but do not want to mess up further my body.

Any of you experience good feeling and ripping body fat at the beginning of the treatment? is this double swords effects a known cause?

Thanks for your opinion
