Not in my experience. I'm taking Alpha T2 now that has 3,3 T2, Methyl Synephrine, and Alpha Yohimbine. I do notice an increase in core temperature after dosing two caps in the AM, but no jitters or rush. It does kill my appetite.
N2Slin is a bad ass product that I use anytime there is a significant amount of carbs in my diet. I ran two bottles back to back dosing two caps before breakfast and two caps before my pre and post workout meals. I swelled up and dropped quite a bit of fat. It's the perfect recomp supp imo.
DS Lean Xtreme is an excellent cortisol control stim free fat burner. For thyroidal, try PES Shift. Another great stackable option is Genomyx DCP if you can get your hands on it!
Agree with all here. I do Alpha T-2 and Forged Burner at the same time and got very good results.
Still, you only need one of those to get what you want.
