I don't know enough about them to recommend them. I'm not a supplement expert. Secondly, I'm also not the guy to go to because I've made good progress without supplements.
Besides, even if supplements did give me an advantage, that reward is worth it to me financially because more pounds on my bench or 10 more pounds of muscle isn't worth money to me (I don't make a living off my physique, nor does my physique impact my quality of life to a great degree so long as I look OK or better with a shirt off).
As I said a million times, I don't see any point with a lot of supplementation if someoen can't even design a diet and training program for themselves and add 20 pounds of LBM within their first year of training. Seriously, what's the point?!
