Today’s episode is all about a peptide called Thymogen. Sometimes you’ll see it spelled Thymagen, but I’ve always preferred “Thymogen” because it just rolls off the tongue. Either way, we’re talking about a bioregulator peptide that works specifically on the immune system, and it’s one that’s been floating around research circles for a while… but I haven’t gone deep on it until now.

Most of you have heard me talk about Thymalin — and I love Thymalin. I’ve used it a lot, and in certain use cases I even like it more than Thymosin Alpha-1. But here’s the key: Thymalin is broad-spectrum. It’s like a full thymus “reset.” Thymogen is more targeted — especially for the “post-viral” use case, that lingering sickness, the recovery phase, or even as a proactive tool when colds and flus are making their rounds. And honestly, that’s exactly why this episode matters right now, because I’ve been dealing with a little head cold myself after travel and lack of sleep.

In this episode, I break down what Thymogen is (a synthetic dipeptide: L-glutamyl-L-tryptophan), why it’s interesting from a longevity perspective, and what we know about its safety history in Russia. Then we get into the mechanisms: T-cell maturation, immune surveillance, neutrophil function, and even some of the signaling pathways it appears to influence like ERK, mTOR-related proteins, STAT1, and chromatin remodeling. I also explain why I see Thymogen as more of an immune modulator than a blunt “stimulator,” which matters a lot if you’re dealing with inflammation or an overactive immune system.

We’ll talk practical benefits — fewer infections, better recovery, inflammation control, and why the animal data is intriguing when you look at lifespan and tumor incidence. Then I’ll give you my straightforward protocol: 1–2 mg per day for 30–60 days, usually once or twice per year as a tune-up… and also how I’d deploy it if you’re actively sick or dealing with something that just won’t clear.

Finally, I’ll compare Thymogen vs Thymalin, and I’ll explain how you can use them together: Thymalin as the foundation, Thymogen as the fine-tuning. And I’ll even touch on when I’d consider stacking them with Thymosin Alpha-1 if you’re trying to cover every base for immune protection.

Before we jump in — thank you. Seriously. As we wrap up 2025, I’ve been overwhelmed with gratitude for the messages from people telling me they’re getting real results. I don’t exist without you guys. Also make sure you’re on the email list (link in the description) so we can stay connected no matter what happens on social platforms. And if you want direct access to me, live calls, and real-time feedback on your protocols, check out the Axion Collective — it’s the community I’m putting everything into.
