Look at "tight"--it's cheap and has a lot of goodness in it.
Synephrine, forslean, yohimbine, Guggul E/Z
I am stacking that with some 7-keto DHEA and I have noticed a big dif. There is some heat going on. After exercising I can feel the heat (noticeable sweating) for about an hour (at least). If I even fast walk to the train station I am sweating on the d*mn vinyal seat for an hour...
Hot Rox has guggle E/Z, and it seems (from my reading) a different version of 7 keto (A7-E--they claim is better), and Salvia sclarea (which they claim is better than forskolin).
It also includes 5 HTP and acetely-Tyrosine (better version of L-tyrosine)
But it doesn't have yohimbine which they claim is uneeded (and tight and others do).
TIght doesn't have the 5 HTP and acetely-Tyrosine or 7 keto DHEA or anything similar. TIght is also alot cheaper ;-)
If they are right about A7-E and Salvia sclarea then I think Hot Rox will turn out to be a good supp and the price wouldn't be out of line either since it'd be compareable to a TIght/7 keto stack.
Thermorexin is something else to look at and really the price is good for the qty of pills your getting.
I'm done with the old ECA/NYC stuff--mostly supressed appetite and didn't really cause heat/fatloss like this. I just became a junky on that stuff. On the new stuff I've probably lost 8-10 lbs of fat in a little over 4 weeks just keeping a healthy slightly caloric deficit with some very moderate refeeds. Havne't lost any strength--it's gone up slightly.
If you read Ulter's post on THermorexin he says he doesn't know if DNP could work better and I don't think that is crap he's talking either. Haven't tried that particular product but I think all the new thermo's are a "next generation" step up. I can say my Tight/7 keto has given me DNP-esque episodes and the heat is definately there and you are irritable and feel crappy but you know it's working!
This new generation of stuff is way better at least for me.
