Oral Finasteride gave me Gynecomastia - Is topical Finasteride a good alternative?

Hi, 9 months ago, I started to use 5% Minoxidil every morning and evening, and 1.25 mg of oral Finasteride every night. Short hair on my temple came back. But last month, I started to get Gynecomastia (My brother - now a class 3 - had the same problem with Finasteride). My GP told me to stop it. I also started to use Zantac and Propranolol 1-2 months before developing Gynecomastia. I can't afford doing PRP or laser. I was wondering if topical Finasteride from minoxidilmax.com works? Thanks!
