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!

Peptides 101
02:18 — The word is out (or should be): peptides are amazing. Peptides can be topical for sure, but today, we’re mostly getting into the topic of injectable peptides (sub-Q). We explain what they are, why we’re obsessed, and what they’re actually doing in your body and your skin.
Morning gamerchanger
03:58 — BPC-157 changed my mornings. For inflammation, joint pain, and not feeling like a 90-year-old when you wake up—this one’s the real MVP.
It’s not just looks, it’s feel
05:56 — Peptides and potent actives like exosomes and copper peptides are the real skincare game changers.
Gut & muscle
10:00 — More on BPC-157 and why it’s the peptide for anyone with gut issues, muscle fatigue, or mysterious soreness that shows up with age (or enter peri/menopause)
If you’re going for ‘glow’
13:25 — IGF-1 and GHK-Cu: for boosting collagen, building muscle, and giving your skin that firm, hydrated, high-functioning glow.
Aging well
17:46 — Epithalon is for lengthening telomeres and basically stopping time. It’s pricier, but it’s the one we cycle just twice a year.
Sleep, metabolism & more
19:26 — A bit on CJC & Ipamorelin for muscle tone and metabolism, plus why some peptides work best when stacked together.
We talk NAD+
20:33 — Not technically a peptide, but we had to mention it. Why NAD+ helps with energy, brain fog, and cellular function (and how to actually take it so it works).
How to start. Safely.
23:10 — You don’t want to be injecting sketchy gray-market peptides. We talk sourcing, pricing, and what you really need to know before starting.
How to inject
28:06 — We demo how we do it—tiny needles, pain-free, and why it’s not as intimidating as it sounds.
