Scott Stevenson delivers one of the deepest explanations of insulin use in bodybuilding we've ever done on Muscle Minds. Using a full presentation, Scott breaks down what actually happens when you combine your body's natural insulin response with exogenous insulin — and why the usual "insulin builds muscle vs. insulin makes you fat" discussion misses so much of the story.
We cover insulin timing, nutrient partitioning, intramuscular vs. subcutaneous injections, GLP-1 drugs, amino acids and protein synthesis, glycogen replenishment, hypoglycemia, and the potentially fatal mistakes bodybuilders can make when insulin becomes too routine.
If you use insulin — or you're even considering it — this is an episode worth understanding before you touch it.
