⁠⁠Insulin vs Muscle Growth: What Really Builds Size in the Offseason | J3U Podcast Ep.231

Everyone says insulin is the secret to getting huge, but is it actually necessary? In this episode, we break down the real role of insulin in bodybuilding, why many athletes are using it less than ever, and what actually drives muscle growth, nutrient partitioning, and offseason progress. We also discuss the few situations where insulin may make sense, plus the biggest mistakes that are destroying progress long before insulin becomes relevant.
