Peptide of the Week: LL-37, VIP & TA-1 – Immunity, Inflammation & Gut Repair

Welcome back, warriors! In this episode of Peptide of the Week, JD Denham and William T. Haas break down three powerful compounds that can help fortify your immune system, combat inflammation, and repair gut and respiratory damage just in time for cold and flu season.
Whether you’re battling long-term autoimmune issues, seasonal bugs, or just want to optimize your body’s first line of defense this episode has everything you need to know.
We cover:
🛡 LL-37 The silent powerhouse antimicrobial peptide– Broad-spectrum antiviral, antifungal & antibacterial protection– Shown to assist with mold toxicity, leaky gut, Lyme disease & even MRSA– Also supports skin & tissue repair, angiogenesis, and wound healing⚠️ Note: May cause allergic reaction or skin irritation in sensitive individuals
💨 VIP (Vasoactive Intestinal Peptide) The flush-inducing lung healer– Bronchodilator that aids in asthma, COPD, and inflammation of the airways– Improves gut motility, digestion, and vascular health– May reduce blood pressure, improve blood flow, and enhance recovery– Potent, so go low: 100–200mcg 2–3x/week max
🔥 TA-1 (Thymosin Alpha-1) The immune thermostat– Regulates immune balance: ramps it up when needed, calms it when overactive– Known for reducing systemic inflammation and supporting autoimmune balance– Floods the system with T-regulatory cells & enhances T-cell response– Widely used internationally (Zadaxin) and by those wanting to prevent illness during travel or stress– Real-world stories: protecting JD’s family on vacation, boosting immunity in high-risk adults, and even shortening illness windows
👩‍⚕️ Can these be stacked together?Yes no known negative interactions when dosed properly. VIP is powerful, so avoid stacking at high doses. TA-1 is great for long-term immune balance, while LL-37 is best reserved for acute infection or mold/toxin-related healing.
💉 Dosing Recap:– LL-37: 100–500mcg 2–3x/week depending on severity– VIP: 100–200mcg 2–3x/week max (flush warning!)– TA-1: 1–2mg daily or every other day (varies by need)
💡 Whether you're heading into winter, managing autoimmune flare-ups, or just looking to stay healthy and resilient, this trio offers real, studied pathways to stronger immunity and faster recovery.
🧪 This isn’t hype it’s hard data, real-world feedback, and first-hand experience.
