Ehpedra Question

i WANTED TO DO THE ECA STACK BUT i DONT KNOW WHAT THE DIFFERENCE IS BETWEEN THE EPHEDRA ALKOLOIDS. CAN ANYONE TELL ME THE DIFFERENCE?

PSUEDOEPHEDRINE HCL
EPHEDRA ALKOLOIDS

WHERE CAN i GET ONE ONE THAT IS A THERMOGENIC? I KNOW THE OTC ONES WITH PSUEDO HCL LIKE IN SUDAFED ARE NOT THERMOGENIC

lose the caps please....pure ephredrine HCL can be found in Primateme caplets and Bronkaid caps at your local drugstore.
