Peptides aren't new and they aren't exotic. A lot of them already exist in nature — some are already in your body. And here's the thing that explains almost everything else: you generally can't patent a molecule that already exists in nature. No patent, no 20-year monopoly, no way to recover a billion dollars in trials. So the easy conclusion is "that's why pharma doesn't care."
But pharma isn't the enemy. Companies like Novo Nordisk and Eli Lilly are the ones actually funding the science — running the trials, doing the safety work, building the road the rest of us get to drive on. That deserves credit, not resentment.
