Should i stop finasteride?

I am 25yo and have been taking 1mg finasteride daily for about 1 year along with topical minoxidil . It definitely has helped reduced shedding and thinning but i would not say that i have gained back any lost ground. I have noticed a small decrease in libido but have had no problem in the bedroom with the girlfriend.

I did not get any bloodwork done prior to starting finasteride, so i have no baseline to go off of.

NOTICEABLE SIDE EFFECTS: I have notcied considerable brain fog and some trouble with short term memory. I work as an electrical engineer so i would say that has been the most noticeable. I also feel that i have had decreased strength in the gym.

Should i stop taking finasteride, wait 3-6 months for it to clear my system, then get bloodwork done?

Any advice/insight would be helpful! Thanks
