Can peptides help us age better? A review looks at nine promising compounds.

What if we could target the underlying biology of aging itself? A new systematic review looked at nine different therapeutic peptides to see how they might fit into that picture. The review found these compounds aim at very different parts of the aging process—like restoring metabolism, protecting the brain, or helping tissue repair. Some, like tirzepatide, are already FDA-approved for other uses and come with safety data from large clinical trials. Others, including BPC-157 and epitalon, show promising results in early lab and limited human studies, but they haven't been through the rigorous, long-term testing needed to prove they're safe and effective for promoting healthy aging. The researchers point out significant gaps in our knowledge, especially around the best doses, how these peptides might work together, and what markers to watch to see if they're actually helping. For now, this review offers a fascinating look at the scientific landscape, highlighting both the potential of this approach and the very real need for more research before any firm conclusions can be drawn.
