Propecia and the gym

[jpm]

Hi,
I've been on propecia for just over 2 months and I've decided to hit the gym. I'd like to put on a bit of weight because I'm quite skinny! Nothing drastic, not looking to body build, just maybe some more strength and muscle definition. I will be going 3 times a week.

Just wondered if going to the gym will affect my propecia, or vice versa. I'm not going to take any supplements like creatine because I have read it can raise dht levels!

Your thoughts would be greatly received
