š¬ My Retatrutide Research Update: The Muscle Building Phase Game Changer
Alright community, it's time to share my experience with retatrutide in a muscle growth/bulking context. Let me break down the science AND my real-world results. Remember all of this info is for research purposes only, not medical advice, and do not copy. Understanding Retatrutide: The Triple Threat Retatrutide hits THREE different receptors. Here's what each one does: šÆ GLP-1 Receptor: - Slows how fast your stomach empties - Reduces appetite through brain signaling - Helps your pancreas release insulin when you eat - Lowers glucagon (which normally raises blood sugar) šÆ GIP Receptor: - Boosts insulin even more than GLP-1 - Improves how your body handles fat and nutrients - Reduces food intake through different pathways - Makes fat cells more insulin sensitive šÆ Glucagon Receptor (THE KEY DIFFERENCE): - Increases your metabolic rate - Burns stored fat for energy - Reduces fat buildup in your liver - Helps preserve muscle during weight changes Why Reta Feels "Weaker" Than Tirzepatide Here's the thing: retatrutide's GLP-1 activation is intentionally weaker than tirz or sema. Why? Because glucagon normally increases appetite and blood sugar. So you need some GLP-1 to balance it out, but not so much that you kill your appetite completely. This is actually PERFECT for bulking. The gastric emptying is there, but way less pronounced. I've never gotten the same food noise reduction on reta compared to tirz. And that's exactly what you want when you're trying to EAT to grow. The "Eat More, Gain Less Fat" Phenomenon This is where it gets crazy. Here's what's actually happening: 1ļøā£ Your Metabolism Runs Hotter Glucagon activation increases your metabolic rate by 5-10%. You're literally burning more calories doing nothing. 2ļøā£ Your Body Burns Fat Preferentially Even when you're eating MORE, the glucagon component shifts your body to burn fat for fuel instead of storing it. You're in a surplus, but calories are being oxidized, not stored. 3ļøā£ Better Nutrient Partitioning
