And they might not have a trusted medical provider to contact if they have questions or, even worse, if something goes wrong.

These people aren’t fringe health nuts. They’re your friends, relatives, neighbors and coworkers who heard there was real promise here, couldn’t find a doctor willing to take it seriously, and did their best with what the internet told them. That's the peptide market right now. It’s unregulated, unsupervised and almost impossible to navigate safely.

There's a lot of conversation about the efficacy of some peptides, their safety and whether they should be allowed. But I'd argue the real issue is much more nuanced.

Is there a downside to taking peptides? What do they do?

When regulators and medical institutions refuse to engage with something patients are seeking, it doesn’t make the demand disappear – and it doesn’t make it safer. It just pushes people into an unsafe gray market. We can't pretend that is a sustainable solution, especially in a world where peptides are part of the future of medicine.

Peptides themselves are not to blame for safety concerns. The real problem is the misinformation and regulatory vacuum around many of them.

Some of the most important medicines we already have are peptides: Insulin has kept people with diabetes alive for a century, and semaglutide is the blockbuster of the decade. Peptides........
