I have tried 17hd in the past and have found it to be a good pre workout sup. I am thinking about doing a 4-5week stack with 17hd and Epistane. What do you all think about that? will it be ok to mix the 2?

Also I have heard you dont need any PCT with Epistane, my buddy took it for a month and a half and only gaind 4lbs and said you dont need any PCT
