Everyone online is talking about peptides like they’re the next collagen powder, but most people are skipping the most important part: is your body even in a state to heal?

In this episode, we sit down with longevity expert Nat Niddam to get clear on what peptides actually are, how they work in the body, and where people are getting this conversation dangerously wrong. We talk about the difference between signaling peptides and bioregulator peptides, why inflammation and gut integrity determine whether you’ll see real results, and why “anti-aging for skin” is not as simple as injecting the trendy thing from Instagram.

We also dig into BPC-157, TB-500, growth hormone secretagogues, and the pineal, thymus, and vascular bioregulators, including when they can accelerate repair, and when they’re a terrible idea. Nat explains why your skin is a mirror of internal stress, mitochondrial function, and recovery, and why trying to force aesthetic results on top of chronic inflammation is like trying to build a house that’s already on fire.

Nat Niddam is a certified nutritionist, longevity practitioner, and one of the most trusted voices in the peptide and bioregulator space. She helps clients approach repair, recovery, and aging with strategy instead of guesswork.
