Need to know is zanax.o25 stronger than 25 zanax?

Dosage doesn't exist: Alprazolam (xanax) comes in many forms. There are 0.25 mg dose forms, 0.5, 1 mg and 2 mg. There is also a 4 mg time-released form. There is no "25" and i think you may be mixing it up with 0.25. There is also no ".025" dose form. All brands are tested to be essentially bioequivalent, so a 0.25 mg dose form of one is the same as a 0.25 mg dose form of another.
