I used to take about 18 pills a day but I stopped a few months ago. Not on purpose mind you - when I went low carb/high fat I stopped eating breakfast. My morning suppliments messed with my stomach and I didn't make the switch to taking them at noon. When I realized what I was doing, I decided to hold off until my blood work last week to get a new base line. So, I just started my suppliments again last week.
That said I do take a pre-workout (usually C4 stacked with NX6 from Complete Nutrition). Since I workout so early, I like having the stims...
A side note - I have been letting carbs into my day and I've put back on almost 9 pounds and it's all in my belly.
Great experiment, but I need to get my shit together again - pretty frustrating.
