Don’t want to derail your thread but I have tried this. http://www.appliednutriceuticals.com/product-drive.php
lol, I got some free samples at a fitness expo in Los angles and I just packed it away in some bags. Well last nite I was cleaning my $$$$t out and I found the pills. Well I used them today (only 3 pills) in the gym and blasted through the workout to the point where I just had to quit MENTALLY to keep me from training too hard because my body kept going; if that makes sense.
Did about 11+sets of 3 reps with the 100 dumbbells (2 weeks ago I could only do 1 set of 3 reps with the 100s and the rest of the sets with 95lbs). Could have kept going but I just stopped because my problems is that I tend to focus on lifting too much (I love it!!). Would have used the 105 but they did not go up that high at this gym.
I will admit though I did just have a B complex shot a week or so ago, so I got to factor that boost in as well. I must have been deficient based on my immediate response from the shot.
