IronRadio is experiencing growth - no pun intended! With a backlog of listener mail this week, the guys answer questions and discuss comments. Several topics get attention in this slightly longer episode. Is vitamin D all it's cracked up to be, and do injections help or hurt? Are health coaching certificates worth anything as a career path? What's the deal with TRT for female lifters? Get answers on these issues and tons more! Lastly, much gratitude goes out to long time Iron Radio friend Korey, as well as Matthew, Stephen, Rory, Zafer, and and ASF for supporting the Iron Brotherhood and Sisterhood so strongly. You are appreciated!
