Don't know if 'Mid South' is your location or the imprint on the pill. In either case no information anyone here can give you will improve your knowledge on what is actually in the pills you have.
Your best option is to buy a drug reagent test kit and test your pills. They're really not that expensive, especially if you get the bottles of reagent which can be used multiple times.
That is a much safer option than going on hearsay & random opinions on the internet.
