Thymalin- Summary
- Orforglipron is an oral, once-daily small-molecule GLP-1 receptor agonist developed by Eli Lilly. Unlike injectable GLP-1 peptides, it is a non-peptide compound absorbed orally without food restrictions, representing a major convenience advancement. Phase 2 trials showed up to 9.4% weight loss at 36 weeks, and Phase 3 trials (ATTAIN program) are ongoing for obesity and type 2 diabetes.
- Thymalin is a polypeptide complex isolated from calf thymus glands (developed by the Russian Gerontology Institute), shown to restore immune function, extend lifespan, and reverse thymic involution. Clinical studies demonstrate improved immune parameters and up to 40% reduction in mortality in elderly patients.
- Half-Life
- ~12 hours (once-daily oral dosing)
- Not well characterized as a complex extract; individual peptides have varying kinetics
