TB4 vs. TB-500 (and lots of other peptide questions answered)

New podcast is live!

Happy Monday!

Taylor and I recently sat down with our friend Sarah Morgan for the inaugural podcast episode in our brand new studio.

If you don't know Sarah, you should. She has a Master's in Nutrition, 20 years of clinical practice, and has been deep in the peptide world for over a decade. She's one of the most knowledgeable voices in this space that most people haven't heard yet.

We covered everything from the foundations people skip to the advanced stuff nobody talks about.

Peptide Secrets Revealed: BPC-157, TB-500, GLP Microdosing & Hormones with Sarah Morgan

FYI, BioLongevity Labs has BioZappetite (an oral small-molecule GLP-1 agonist) on sale for 20% off. You can get an additional 15% off when you use code HUNTERW at checkout.

Here's What We Got Into

Why peptides aren't magic bullets, and the one thing most people skip that makes their peptides not work

The real difference between Thymosin Beta 4 and TB500 (and when you actually need the full peptide vs the fragment)

The cycling strategy I personally use that extracts more net healing from fewer peptides

GH secretagogues and anaphylactic reactions. Yes, this happens even with compounding pharmacy peptides. Sarah explains who is most at risk and what to have on hand.

The connection between histamine issues, mast cell activation, and why certain peptides don't work for you

Microdosing GLPs for autoimmune and immune modulation.

Why some people get absolutely wiped out on GLPs and what that actually means about their health

The mitochondrial peptide stack Sarah just ran, and why she uses Humanin before SS-31 and MOTS-c

Hair loss on GLPs. What's really going on and why it's not just a thyroid problem.

Why MOTS-c plus Retatrutide could be a crash and burn combo if you're not careful

NAD+ as a tool vs NAD+ as a crutch. How to know the difference.

The case for Thymosin Alpha 1 as the most underutilized peptide in the next 3 to 5 years

Stanford data showing we have a massive metabolic aging event at age 44 and an immune aging event at age 60

How BPC actually rescues healing even when someone is on corticosteroids

This was one of those conversations you're going to want to take notes on.

Learn Peptides The Right Way

Sarah just launched a course called Amino Academy, and I went through it myself.

The way she organizes it by systems biology instead of just listing peptides makes everything click in a way that random social media posts never will.

It covers the mechanism of action, dosing, cycling, contraindications, clinical applications, and full PubMed papers for every compound. There's a quiz at the end, and you get certified when you pass.

Whether you're a practitioner, someone deep in the peptide world, or just getting started and want to actually understand what you're putting in your body, this is the course.
