TA1
Thymosin Alpha 1
Thymosin Alpha-1 (TA1) is a naturally occurring peptide derived from the thymus gland, which plays a central role in regulating the immune system. TA1 works by enhancing the activity of T-cells and other immune cells, helping the body fight off infections, viruses, and even some forms of cancer more effectively. It also improves the body’s ability to detect and eliminate abnormal or damaged cells, making it valuable in immune support, chronic illness recovery, and overall immune optimization.
Clinically, TA1 has been used to treat viral infections, autoimmune disorders, and immune deficiencies, and it’s often included in wellness or longevity protocols to enhance immune resilience and recovery. It’s especially helpful in people with weakened immune systems or those under chronic stress. Because of its immunomodulatory effects, it can help restore balance—stimulating a weak immune system while calming an overactive one. TA1 is typically given by subcutaneous injection and is considered safe, well-tolerated, and highly versatile in both clinical and wellness-focused settings.
Protocols
1. Immune System Enhancement (General Use & Prevention)
Dosage: 1.5–3 mg per injection, 2–3 times per week
Cycle: 6–12 weeks, with reassessment
Administration: Subcutaneous (SC) injection
Stacking: Often combined with BPC-157, Glutathione, or NAD+ for immune optimisation
Expected Benefits: Increased resistance to infections, enhanced immune surveillance, improved recovery from illness
2. Chronic Viral Infections (Hepatitis B, Hepatitis C, EBV, HIV, COVID-19)
Dosage: 1.6–3.2 mg per injection, once daily or every other day
Cycle: 6–12 weeks, followed by evaluation
Administration: SC injection
Stacking: Works well with Interferon therapy, Zinc, and Vitamin D for antiviral effects
Expected Benefits: Improved viral clearance, reduced disease severity, enhanced immune function
3. Autoimmune Disorders (Lupus, Rheumatoid Arthritis, Multiple Sclerosis)
Dosage: 1.5–2.5 mg per injection, 3 times per week
Cycle: Long-term use possible with periodic breaks
Administration: SC injection
Stacking: Often combined with Low-dose Naltrexone (LDN) or Thymosin Beta-4 (TB-4)
Expected Benefits: Reduced autoimmune flare-ups, balanced immune response, lower systemic inflammation
4. Cancer Immunotherapy Support
Dosage: 3–5 mg per injection, 2–3 times per week
Cycle: Ongoing use as adjunct therapy
Administration: SC injection
Stacking: Can be used with Checkpoint Inhibitors (e.g., PD-1 blockers), Curcumin, or Resveratrol
Expected Benefits: Increased tumour recognition by immune cells, reduced tumour progression, improved treatment outcomes
5. Chronic Fatigue Syndrome (CFS) & Fibromyalgia
Dosage: 2–3 mg per injection, 3 times per week
Cycle: 8–12 weeks, followed by assessment
Administration: SC injection
Stacking: Works well with MOTS-c, CoQ10, and Magnesium for mitochondrial support
Expected Benefits: Increased energy levels, reduced inflammation, improved overall well-being
Further reading
TA1 works by directly activating T-cells, boosting natural killer (NK) cells, and enhancing immune homeostasis. It is unique in that it not only strengthens immune responses against infections but also prevents excessive immune activation, making it particularly useful for autoimmune conditions and chronic inflammation.
Studies have demonstrated that TA1 can improve immune function in elderly individuals, where thymic decline leads to weakened immunity. Its ability to regulate cytokine levels has also made it a promising treatment for cytokine storms in severe viral infections, such as COVID-19 and sepsis.
Another key area of interest is TA1’s role in cancer therapy. Research suggests that tumour cells often suppress immune function, allowing them to evade detection. By enhancing immune surveillance and tumour recognition, TA1 may help improve the efficacy of chemotherapy and immunotherapy treatments.
Despite its promising effects, TA1 remains under clinical investigation in many countries, though it has been approved for medical use in some regions, particularly for chronic viral infections and immune dysfunction disorders.
Potential Side Effects
Mild flu-like symptoms (temporary)
Injection site reactions (redness or swelling)
Temporary fatigue (due to immune activation)
TA1 is generally well-tolerated, non-toxic, and does not suppress immune function, making it a safe long-term option for immune modulation.
