Python Metabolite Sparks GLP-1–Free Weight Loss Hint
Scientists from CU Boulder and Stanford identified a python-derived gut metabolite, para‑tyramine‑O‑sulfate (pTOS), that after being tested in mice triggered weight loss through hypothalamic pathways without muscle or energy loss, suggesting a potential natural alternative to GLP‑1 weight‑loss drugs and prompting Arkana Therapeutics to pursue a synthetic version.
