I have used regained foam for around 15 years I would take propecia but I am extremely worried about the side effects, especially since I experienced some bad side effects from taking a small daily dose of saw palmetto for 4 months.My thyroid test came back normal and I am currently waiting on a result of a shot test. If my DHT comes back in the low range then is it a bad idea to take propecia, especially after having a bad reaction to saw palmetto?
