Season Finale: Tons of New Meta-Analyses and Q&A Catch-Up

Today’s episode starts off with a Good News segment and some brand new Feats of Strength. After that, Eric discusses his most recent SBS article about Betaine, and addresses some of the feedback that the article has received. This segment opens up into a broader discussion about how to evaluate a new body of research as it’s developing. Topics include conflicts of interest, how much evidence is required to justify experimentation, and when we can confidently conclude that an intervention simply doesn’t work. Some historical examples are discussed along the way, with some background information about how the steroid, creatine, caffeine, and citrulline malate literature developed over time. After that, Greg and Eric share a quick Research Roundup segment, followed by some off-topic questions To Play Them Out.
