At a Glance Dose Range Imunofan 50–100 mcg Thymosin Alpha-1 1.6–3.2 mg Frequency Once daily Twice weekly Administration Subcutaneous injection Cycle Length 8-12 weeks Onset Speed Rapid (hours to days) Moderate (1-2 weeks) Evidence Level Limited human trials Moderate human trials (Phase 1-2) Efficacy Immune Healing & Recovery Anti-Aging Immune Activation Infection Fighting Immune Balance Technical Data Molecular Formula C36H61N13O10 Molecular Weight 836.0 g/mol Half-Life Approximately 2-4 hours (intranasal administration) Bioavailability ~90-95% (subcutaneous injection) CAS Number Not assigned (Russian pharmacopeia compound) C129H215N33O55 3108.32 g/mol Approximately 2 hours High when injected subcutaneously (rapid absorption, peak at ~2 hours) 62304-98-7 Protocols standard 45 mcg per dose Once daily or every other day Course of 5-15 injections (about 10-30 days) Standard injectable dose per the Russian pharmacopeia product label; the single subcutaneous dose is 45 mcg with a maximum daily dose of 45 mcg. Given in courses depending on the indication [1][5]. Same 45 mcg single dose can be given intramuscularly; identical course structure to the subcutaneous route [1][5]. 50 mcg per dose (one spray in each nostril) Once to twice daily 8-15 days per course Intranasal spray delivers 50 mcg per dose; one dose into each nasal passage once daily for 8-10 days, or twice daily for 10-15 days for certain indications [5]. 1.6 mg Twice weekly (3-4 days apart) 6-12 months Established clinical dose for thymalfasin (Zadaxin); body-surface-scaled as 900 mcg/m2 [4][6]. Phase III chronic hepatitis B trials used 1.6 mg SC twice weekly for 6-12 months [4]. advanced 1.6 mg daily, then 1.6 mg twice weekly Daily for an initial loading period, then twice weekly 12+ weeks Some immune-adjuvant and acute protocols front-load with daily dosing before settling to the standard twice-weekly schedule [4][6]. Applications Cancer Adjuvant Therapy Imunofan enhances the body's reserve capacity to inactivate free radicals and oxidants during chemotherapy and radiation, substantially reducing toxic reactions and enabling continuity of cancer treatment. Its unique ability to inhibit multiple drug resistance proteins may also improve chemotherapy drug effectiveness. Chronic Viral Hepatitis With established hepatoprotective properties and immune-restoring capabilities, Imunofan is used as adjunctive therapy in chronic hepatitis B and C, helping restore antiviral immunity and supporting liver function recovery. Chronic Infections with Immunodepression Patients with chronic infections (brucellosis, opportunistic infections in HIV) who display cell-mediated immunodepression may benefit from Imunofan's three-phase immune restoration, particularly the sustained slow-phase effect lasting up to 4 months. Oxidative Stress Reduction The rapid antioxidant phase makes Imunofan valuable for conditions involving elevated oxidative stress, as it directly inactivates free radicals and peroxide compounds while restoring the body's oxidative-antioxidant balance. Chronic Hepatitis B or C Support Thymosin Alpha-1 has its strongest clinical evidence here. Multiple trials show it helps clear viral loads and normalize liver enzymes, especially when combined with antiviral medications. It's approved in over 30 countries specifically for hepatitis treatment. Cancer Treatment Support When used alongside chemotherapy, Thymosin Alpha-1 may help maintain immune function that chemo tends to suppress. Research in lung cancer, melanoma, and liver cancer shows improved outcomes when added to standard treatments. It helps your immune system keep fighting even during tough treatments. Age-Related Immune Decline As you age, your thymus shrinks and produces less thymosin naturally—a process called immunosenescence. Supplementing with Thymosin Alpha-1 may help compensate, keeping your immune defenses more youthful and responsive. Think of it as replacing what your body makes less of over time. Severe Infection Recovery In sepsis and critical infections, Thymosin Alpha-1 has shown promise for reducing mortality by helping restore immune balance. It's particularly interesting because it modulates immunity rather than just boosting it—calming overreaction while enhancing pathogen-fighting ability. Safety Profile Common Injection site reaction Transient headache Nasal irritation (intranasal form) Transient mild fever Mild fatigue Gastrointestinal discomfort (suppository form) Uncommon Allergic reaction Serious Anaphylactic reaction / Severe hypersensitivity Injection site reactions Flu-like symptoms Mild fever Lymph node awareness Research Status FDA Status Research compound Safety Overview Imunofan (Iletin-alpha, a synthetic tetrapeptide) demonstrates good tolerability in Russian clinical practice spanning 20+ years with oral and parenteral administration. Immunomodulatory peptides carry theoretical risks of over-stimulating autoimmune responses, but Imunofan safety data show no increased autoimmune flare rates in patients with existing autoimmune conditions. Injection site reactions and mild fever (1-3% of users) are the documented adverse events, not immunotoxicity. The mechanism of enhanced T-cell maturation appears selective and safe at therapeutic doses. Contraindications xKnown hypersensitivity to imunofan or excipients xPregnancy complicated by Rh-conflict (contraindicated) xChildren under 2 years of age xSevere allergic conditions in acute exacerbation FDA approved for other use Thymosin Alpha-1 has one of the most extensive safety records of any peptide, with decades of clinical use across multiple countries. Studies consistently report minimal side effects—mostly limited to mild injection site reactions. The 2-hour half-life means it doesn't accumulate in your system. It's been used safely in thousands of patients with hepatitis, cancer, and other serious conditions. xOrgan transplant recipients on immunosuppressants xActive autoimmune disease flares xKnown allergy to thymosin peptides xPregnancy or breastfeeding xChildren under 18 without medical supervision Decision Guide Choose Imunofan if...
