I'm on Ephedrine Sulphate, (bronkaid), 200mg caffeine, & 81mg aspirin, plus 2mg of Ketotifen nightly to keep the receptors clean. I've stacked this with Stacker 3's, the new versions of Alpha T2 &, & the old versions with dmaa/1,3-Dimeth in them. Since the ECA stack does work well, I still need more energy with my high tolerance, & so without double dosing the bronkaid, i'd rather find something else. Now i'm thinkin of grabbin some Ephedra Extract, or Synephrine HCL, where I believe the combination of the 2 may give me what im lookin for, but my thread here to ask u fine folks on what u think & what u would recommend? works well for a few days then dies off so that's a no go. Green Coffee beans, Rasb Ketones, Green Tea, & all the helpers, yadda, yadda, that do little for energy & i'm really not in the need for fat burners, but would consider them if they can produce the energy wanted! What do u guys think?? Maybe try some Synephrine HCL, or Yellow Bullet, or Lipoderen w/Eph, or Green Stingers???
