Let me also point out this: if you are prone to finasteride sides, nothing can mitigate them once they get going. It only gets worse as the time goes by. Take me for example:
31 now, 6' 220 lbs. I'm a Marine Corps Officer who trains 6 times a week. I squat 500 lbs and run/swim/bike, in that order, every week. I also have done PE for my c***. Manual Jelqing, stretching, etc. This stuff works and does increase your eq/c*** size. All of this didn't amount to sh*t with finasteride. It completely nullified all of those potential stop-gap measures to prevent ED. Yohimbe didn't work, Maca didn't work, Agmatine and L-Arginine, test boosters didn't work. Nothing. If these sides strike you, good luck Chuck is all I'm going to say.
Also, at first finasteride did in fact make a positive impact on my sexual performance, but that was due to increased Test levels. That too, reversed course and took a turn for the worse. I had literally every single positive measure you could have to mitigate the potential negative effects of finasteride and it still drowned me in sides, the way IRMA drowned the Caribbean.
