I'm a "she"... Here's the deal.... It's simple. I ordered from Shop Slim on 7/16. received my order on 7/28. Took it for two days.... Didn't see/feel the "ephedrine" effects. Tested it to see if it was ephedrine or possibly under dosed.. and it didn't contain ephedrine period. I have no idea what it is but I can guarantee you what it isn't.
