Playing with finasteride dose without side effects

Thinking about doing 0.5MG 3 times a week. Would this be effective at removing some of the DHT from the scalp? I want to start using FIN but worried about the sides, so i wish to start gentle. Is there anything you can recommend that I do before starting FIN? I am going to ask for blood work done soon to measure my hormone levels.

You are not making sense to me. If you don’t have side effect, use the full dose of 1mg. If you develop side effect (a 4% risk at most), then you can play with a reduced dose.
