My history is fairly typical of others except I got this shit from Avodart although I had used propecia in the past too. I first noticed a problem end of December 2016. I had just restarted Avodart and I had done this so many times in the past. Sometimes I would stop because I ran out or just didn't feel like taking it. I never had a problem for ten years. In fact when I restarted Avodart I'd usually notice an boost in libido and maybe even couple pound wt loss. Anyway, I noticed this drop in libido and I remember initially thinking could this be avodart but I actually thought it wasn't because I had been on it so long with no problem. Then about a month later (beginning of Feb) I felt great. Better than average libido and clear thinking no anxiety. Of course that didn't last and by mid February I was struggling! Very anxious, clouded thinking and no libido. Avodart has such a long half life I thought it might get better by April. Of course that didn't happen. I found Propecia help in May and started doing the Progesterone protocol as described by Light at end... So over the past year or so I have had times of feeling almost normal but then had relapses. I think for the most part my anxiety issue is better except having a racing heart rate sometimes before having sex with my wife which doesn't always work, if you know what I mean. This shit has damaged so many lives and I have seriously thought that it could cause a divorce for me. It's so hard to explain to your wife/ partner that you find them attractive and want to be with them and you struggle to get an erection! Not good!!! Anyway, my thoughts are that I think Progesterone may have an important part in the cure for some with PFS. Clearly it doesn't work for everyone and maybe can worsens symptoms for some for unclear reasons. The addition of Ella/RU may help reset something and may augment the effect of Progesterone. Interestingly in May I had been cycling Ella and Progesterone and felt like I was not getting a benefit so I stopped everything in frustration but after the 4 day snap back I was doing so close to prePFS I thought I could be cured! This lasted a good 6+weeks. But unfortunately for some reason symptoms returned. My thoughts (like otheres) are that for some undescribed reason finesteride/avodart damaged the androgen receptor. Progesterone helps paradoxically for some ppl for unclear reasons. My goal is to continue trying different things to try to fix the damaged AR. If finesteride modulated the AR, could there be something that can reset this? I think progesterone and antiprogesterones (RU/ella) can increase AR expression. I think that could be the reason for improvement. So even if they are damaged, if you have more of them maybe some additional signalling can occur. I don't think anyone knows very much about PFS with certainty. I recently tried Anavar. I have higher T and higher level of DHT and adding Testosterone injections could help for like a day, maybe. Taking Arimidex ( small dose) can also help me for like a day. I think both of these maneuvers will increase testosterone but since the AR is damaged, no signficant benefit. I think progesterone/ RU/Ella can help more because of the possible increase in AR expression. Anyway 5 days after Anavar had great libido like prePFS that dropped some but I think I am still above baseline. That trial was clouded as I also took some topical progesterone. This is all just my opinion and I definetly could be wrong.
