In the past, I've certainly loved my stimulants, HotRoxx being at the very top of the list. Lately though, I've gotten into my head the notion (too much reading) that excessive stimulant intake can actually raise cortisol levels, and promote muscle loss when dieting, so I've taken a little break to see how things go.
Still, I grab a cup of coffee on those afternoons whenb I'm just totally dragging my ass. We're not talking about a 20 oz Espresso here, just a plain cup o' joe from the corner store on my way to the gym. Not only is it a hell of alot cheaper than those NO products, but in all honesty, I never really got the impression they really did much.
