So i've started using 0.25 finasteride im' in the secound month. By far the only side that i've got was testicular pain at the begin now the pain went down. About the libido and the erection stuff can tell got because before i started finasteride i was hardcore cigarete smoker and weed so they weren't in good contition because of my unhealty life. Any blood test that can see if the finasteride is well welcome to my body or messing with my hormones. I think that the 0.25 dose works really got few darker hair so i guess i'm having sheed, can't tell it for sure because i have long hair but i think that have effect on the body. Also i tryed .50 but the testicular pain was more common, the 0.25 dose make me to feel more normal
