I received my Arr order today. On the invoice it says Liquidex, which is what I ordered. But on the bottle it says lquid letro?? I assume I got the wrong thing but want to make sure. Im assuming these arent interchangable. Letro says 2.5mg/ml, where as liquidex is 1mg/ml. Should I send it back, order again?? Not sure what to do, looking for suggestions. Thanks
