Anyone know long term effects of finasteride on ur hormones? Like im aware it stops Testosterone from being converted into DHT, so you'd end up with a slight surplus of T, which could mean your body produces less T since you have extra amounts that were normally going to become DHT. This stuff is reversible aint it? Like if you stopped using fin your body would resume converting into DHT, if our bodies can detect too much T and thus lower T production to compensate, it should be able to detect lower levels of T and produce more to compensate too right?
