After 6 days on the boosters:
A while ago, my fighting instructor put me and some other students on a diet/workout routine. I was on it for a few weeks before starting the boosters. In two weeks without them, I lost between 1 and 2 pounds. In less than a week taking the boosters, I've lost between 7 and 8 pounds, and I weigh less than I have in years. But I'm still gaining muscle, too. My instructor (who doesn't know that I'm taking the boosters) said that I look fitter, and that I'm stronger than I've ever been. When we fought today, he was working just about as hard as me, and I even beat him a good amount.
My muscles are aching but they're growing, not only in strength but visibly, too.
I haven't noticed any increase in anger levels, or any increased irritability.
