What's That?

My mom was just telling me about this thing in creams called Phentermine 37.5. Apparently it's quite powerful and helps wrinkles better than a lot of others do. It must sound good because she rarely gets sucked into anything trendy or what not. Every now and then she comes to me asking about something because she assumes I would know from her being late in the game. I think it's funny because I think I might be further out of the loop than she is.
