In this new episode of Bathroom Diaries, I sit down with Dr. Rob Frankel, emergency physician, anti-aging specialist, and host of the Modern Man Podcast, for an honest, science-forward conversation about one of the most talked-about tools in modern longevity: peptides.

But this isn't hype.

This episode goes beyond TikTok trends and biohacking buzzwords. We unpack what peptides actually are, how they work inside the body, who should (and should not) be using them, and why precision and medical integrity matter more than ever in this space.

Dr. Frankel explains peptides as "text messages" to your cells, signals that enhance your body's own intelligence rather than override it. We explore where peptide therapy shows real promise, where caution is essential, and how innovation can coexist with responsibility.

In this episode, we talk about:

* What peptides really do at a cellular level * The difference between enhancement vs. "sledgehammer" medicine * GLP-1s, Tesamorelin, BPC-157, NAD, GHK Copper & more * Peptides for metabolism, recovery, cognition, skin & longevity * Why not every body is a candidate * The danger of self-prescribing from the internet * How peptides fit into a whole-body, intelligent aging strategy

This conversation is for anyone curious about longevity, aesthetics, metabolic health, and the future of personalized medicine, without the smoke and mirrors.

Because aging well isn't about chasing trends. It's about understanding your biology and guiding it wisely.
