Are Peptides Worth It for Muscle and Aging?

Peptides are often promoted for muscle growth, anti-aging, and recovery, but the category is broader and more complicated than many online claims suggest.

This episode looks at why peptide trends feel so compelling, how different types of peptide products get discussed together, and why evidence for one specific use should not be stretched across every promise. You’ll hear how collagen peptides fit into the conversation, where the evidence appears more targeted, and why broader claims about performance or aging can move ahead of what high-quality research can support.

The goal is not to dismiss curiosity, but to make the question more precise: which peptide, for which outcome, in which context?
