This episode of Iron Culture begins with a rant/story by Dr. Trexler that highlights some issues with scientific publishing. He describes a study on apple cider vinegar, his MASS article criticizing the study, and the subsequent letter to the editor (and response from the original authors). This discussion is followed by a Q&A session with Dr. Helms covering protein during weight loss, headaches from creatine, machines for joint comfort, mixing creatine + caffeine, low volume training for hypertrophy, biceps curl variations, fiber recommendations, and more.
The MASS crew records Iron Culture LIVE on YouTube, Monday nights at 7pm eastern time. Be sure to join us for a future episode and say hello in the live chat!
