So I’ve been reading up on a ton of articles and threads of info and havnt come aBambss what I am looking for yet so I figured I’d just ask you guys.
I do Crossfit and have been for over 3 years and just started taking test. A buddy of mine said it would be smart to stack and that no one just takes test. So my questions are, should I look into stacking? If so, what would you recommend? I’m not looking to bulk, cutting would be best.
