T2, not T2 Pro

I found a supply of ther original T2 at a store. Is it still good?, and how much better is it than T-2 pro???

Should still be good. Call Biotest if you’re not sure and ask about shelf-life. Both work well, just through different mechanisms. I like T2-Pro since you don’t have to cycle it. For a while there I had a couple of females going back and forth between the two and both had excellent results.
