Problem with Topican Finasteride, sides

Hello, I have a problem and I’m looking for a solution. I’m almost 30 and have had hair thinning, a receding hairline, and my hair simply isn’t growing as long as it used to for about five years. I Bought topical finasteride 60ml with 5% minoxidil and 10mg finasteride. I decided on the topical form because of the possible side effects. To achieve this, I sprayed 1.5ml once a day before bed. The first effects that appeared were: respiratory shallow breathing, which causes heart damage, and side effects. After the first two treatments, they started to get used to them, or I simply wasn’t paying attention to them. The problem started after two breaks. I couldn’t have morning erections. My libido dropped to zero, and when I had sex, my penis wasn’t hard, but soft like a jelly bean. It didn’t appear or move in that direction. After all this, I stopped the treatment. I’m wondering if I should try again and hope that the side effects will go away on their own, or if it’s better to give up on it since I’m already experiencing such side effects at the beginning of the treatment.
