Re: are you taking any nutritional supplements?
Just whey isolate, fish oil and a multi. I've tried BCAAs during my workouts and noticed no difference in recovery, so I quit buying those.
I've also tried most every popular pre workout on the market. 1,3DMAA products are my favorite but I had to quit taking them because I was concerned about false positives on a drug test (I've read many conflicting things about this and I would rather be safe than sorry). I've switched over to 400mg caffeine preworkout and have noticed no drop offs in strength or endurance, so the boost from 1,3DMAA is 100% mental. It's still nice to get you in the mood though and if I didn't have to drug test I would probably still be taking it.
