Injectable aka Sub-Q Peptides: Yay? Nay?
In this episode, we dive into the fascinating world of peptides—what they are, how they work, and why they’ve quietly become the holy grail for healing and aging well.
From BPC-157 to IGF-1, we talk through the injectables that are changing how we show up in our skin, our joints, and even our minds. (Yes, there’s one for brain fog, too.)
We break down the difference between topical and sub-Q peptides (injectables), what they actually do inside the body, and which ones have given us the most noticeable results.
There’s also a short pep talk on sourcing safely—because not all peptides are created equal.
If you’re curious about how to feel stronger, look glowier, and maybe even lengthen your telomeres (after listening this will all make sense), this one’s for you.
Enjoy!
