No one can give you a definit answer since we’re all chemically different and finesteride (or any other drug for that matter) would practically affect everyone differently. Yes, there can be many similarities w.r.t. symptoms but baseline for every person is different.
I can tell you from my own personal experience is that it may not necessarily be low DHT per se. It’s best to get all necessary hormones tested and try and look at the big picture. Low DHT should result in higher E2 conversion (theoretically speaking) so if you can measure LH, FSH, TSH, FT3 & FT4, Testosterone, DHT, E2, Cortisol, DHEA-s & SHBG then you can get a better idea and develop a recovery plan that fits your particular situation.
