In my experience it does make a little bit of a difference. The gains are definitely still there but they are less from the DHT side of things. It’s a little hard to explain but overall your free testosterone will be higher, which is good, but DHT will be lower. Higher DHT levels will give me a harder look and also makes me feel really good and happy. It’s not like the gains won’t be there on Fin, you’re just missing out on some of the DHT benefits (and sides). Supposedly, the increased free T you get will make up for the loss of DHT. I would say that’s mostly true.
I’ve never heard of Fin effecting your fertility. I know some people can suffer erection problems. Maybe someone else will chime in about that.
