REDEFINE-1 (Garvey 2025, n=3,417) reported about 22.7% mean weight loss at 68 weeks in adults with obesity without type 2 diabetes; REDEFINE-2 (Davies 2025) confirmed the result in T2D. This post explains the trial, why the December 2024 press release crashed Novo Nordisk's stock, what the amylin arm actually does mechanistically, and how CagriSema slots against semaglutide STEP-1, tirzepatide SURMOUNT-1, retatrutide TRIUMPH-1 topline, and survodutide phase 2. Includes an interactive next-gen weight-loss projection tool. For educational purposes only.

TRIUMPH-1 (NCT05929066, n=2,339) reported mean weight loss of 19.0%, 25.9%, and 28.3% at the 4, 9, and 12 mg doses over 80 weeks, with a higher-BMI extension reaching 30.3% at 104 weeks. Walks the dose-by-dose data, the cardiometabolic secondary endpoints, the dose-related GI and discontinuation profile (11.3% at 12 mg), and why retatrutide remains investigational and not FDA-approved. Topline data announced May 21, 2026. For educational purposes only.

Walks the major goal-categories -- recovery and injury (BPC-157, TB-500), GLP-1 fat loss (semaglutide, tirzepatide, retatrutide), longevity (epitalon, NAD+, MOTS-c), growth-hormone and performance (ipamorelin, sermorelin, CJC-1295), cognitive (Semax, Selank), and skin (GHK-Cu, melanotan) -- grades how mature the human evidence is for each, and covers who should hold off (pregnancy, tested athletes under WADA, certain conditions) plus the questions to ask yourself and a clinician.

Explains the knee extensor mechanism and patellofemoral joint forces, what too much too soon really means for load management, and how runner's knee (patellofemoral pain), patellar tendinopathy, IT band syndrome, and bone stress injuries differ.

A clear-eyed evidence review: gastric stability (pepsin resistance), the rat drinking-water gut data, the 2022 intramuscular pharmacokinetics (14-51% bioavailability, sub-30-minute half-life), the absence of any oral pk study in any species, and the honest human-evidence ceiling. Compares oral, sublingual, subcutaneous, and intramuscular routes. For educational purposes only.
