Anyone have any practical experience or thoughts on the effects of long term thermogenic use. I don't mean any single substance in particular, but I am referring to the overall stimulant (ephed/Synephrine, etc) type products.
I personally am pretty sensitive to these products, so I always have to under dose them (according to the label) or eat them with a full meal, or I get the shakes. But, I lean pretty heavily on them when I need a kick in the ass to get moving throughout the day, or to hit the gym as hard as I'd like.
All the labels say to cycle their use and I am curious as to any of you experts advice. In particular, do you think long term use could actually slow down your BMR, as well as any effectiveness, or health concerns. Let me know, I'm all ears.
