We break down the real mechanistic differences between semaglutide, tirzepatide, and retatrutide (and why stacking GIP with glucagon suppression changes everything), why retatrutide's aggressive fat-burning comes with a real cost — elevated heart rate, HRV crashing, and in some of Jason's female and perimenopausal clients, lost muscle instead of fat — and why the "strongest" drug isn't automatically the right one for your hormone profile. Jason also breaks down his own experience pairing GLP-1s with small-dose fast-acting insulin, his tapering protocol for coming off after hitting a goal, and why he considers GLP-1 + HRT one of the most underused combinations for menopausal and andropausal clients. Pulled from thousands of patient cases across his coaching business and his HRT clinic, this is the guide for anyone using — or considering — a GLP-1 as an athlete. KEY TAKEAWAYS: Why Semaglutide, tirzepatide, and retatrutide aren't interchangeable Retatrutide's triple mechanism burns fat fastest, but there’s a catch for some populations The real cost of retatrutide most people ignore and how Jason manages it Jason's "Slingshot Method" to grow from GLPs The best use case for GLP-1s and metabolic function CHAPTERS: 0:00 Where everyone gets GLP-1 use wrong 1:36 Semaglutide vs. tirzepatide vs. retatrutide — the mechanism explained 8:59 The female retatrutide cases — when the "strongest" drug backfires 17:49 Mitigating Reta’s HRV and heart-rate cost 23:15 The origin of the Slingshot Method 27:29 Stacking fast-acting insulin with the slingshot 32:02 The post-prep tapering protocol 36:58 Menopause, HRT, and why it's the best GLP-1 use case 46:27 Ancillary tools: metformin, berberine, Jardiance 52:12 The GLP Mentor app + where to find Jason Connect with Jason: Scooby-U coaching (on the Mighty app) — or DM @ScoobyHealth on IG HRT & peptide clinic: https://advancedvitalityhrt.com Supplements: https://newethics.com GLP Mentor app (AI coaching for GLP-1 users) — Apple App Store Books on Amazon — search "Jason Theobald": The IBS Fallacy, GLP-1 for Seniors, Menopause guides, 5-Minute Mediterranean Cookbook for GLP Users
