Norephedrine vs ephedrine

why do they put nor in NYC? Is there a good reason I cant use straight Ephedrine HCL? do a ECY? Is nor somehow better for this and if so can I get straight nor?

It's probably done solely for differentiating the product. Ephedrine and norephedrine are essentially analogues of epinephrine and norepinephrine (aka adrenaline and noradrenaline). I haven't found any significant differences between E and NE. Both are catecholamines, both are released from the adrenal medulla, and both are classified as biogenic amines.

About the only difference between the two that I know of is the number and area of brain neurons upon which each hormone exhibits action.

i use them both now, seems to me ephedrine is better . I have prolab therma pro, thats stuff is awesome.

bigpump are you using the both at the same time? Right now I use Ephedrine HCL and Caffine.
