I recently got a refill on my pills yesterday and when i looked at them they where different looking. I throw the bottle way for the first one but the one that i have now was says Mfg: Mutual at it's 37.5 mg also so I'm really not sure what's up with that. I filled my prescription at the some place. That's worried huh?. I know my last bottle made me feel tired but today i fell great. I guess I'll see how i feel in a couple days.
