Low-dose naltrexone is one of my favorite compounds out there, and in this updated 2026 episode I'm breaking down why it deserves a spot in your protocol. I cover the four mechanisms that make LDN work: the endorphin rebound, the OGF/OGFR axis, TLR4 antagonism, and broad anti-inflammatory signaling. Then I get into where LDN actually shines clinically. Autoimmune conditions like Hashimoto's and Crohn's. Chronic pain and fibromyalgia. Depression. PCOS and fertility. Even skin issues like acne, which I've personally dealt with for years.
But the part I'm most excited about is how LDN stacks with hormones and peptides. I walk through why it pairs so well with TRT, estrogen, and thyroid optimization, and then I get into specific peptide combos including BPC-157, TB-500, thymosin alpha-1, KPV, SS-31, and GLP-1 agonists. I also share why LDN might let you stay at lower GLP-1 doses for longer.
I cover dosing, titration, side effects, and my own experience cycling versus staying on continuously. If you're already optimizing with peptides and hormones, LDN might be that last five to ten percent that makes everything else work better.
