I have 100 stacker 3 pills purple and pink. They have ST-3 224/3850 stamped on them. Are these the original with ephedra or not? I have searched and all I can find is ST3 EF 224/3850 only any web search. Does anyone know if these are ephedra based or not? thanks...
This particular imprint (Stacker 3) comes back as a purple/pink capsule with the normal list of useless herbals, but it also lists ephedra as an ingredient. (The same imprint with the "EF" added would mean ephedra-free, and these have a purple/gray color scheme.)
On the above imaged ST-2 224 3850 (Stacker 2), there are actually three capsules with the same imprint, but a different color scheme and ingredients:
--The one shown above by Phisher (nice image Kirby) is a yellow/blue capsule and that is ephedra-free.
--There is also an all yellow AND a yellow/pink capsule that are both listed as containing ephedra.
It's quite a maze of colors and ingredients, buyer beware.

good question. i am not really sure. i know that the ones pictured below are marketed as ephedra free which would lead me to believe that the ones that you have do have ephedra in them however this is only a guess and i may very well be wrong.i am sure that some of the other posters might have more insight to this. check back in a bit and i bet you will have a more concrete answer.sorry i cannot be of more help.
