Thymosin Alpha-1 by Dragon Pharma is a clinically proven 28-amino-acid peptide identical to the naturally occurring thymic hormone. Each vial contains 10 mg of lyophilized, pharmaceutical-grade Thymosin Alpha-1 — one of the most powerful immune-boosting and regenerative peptides currently available in research and performance circles.
What It Is
Thymosin Alpha-1 (Tα1) is a major component of Thymosin Fraction 5, naturally produced by the thymus gland. It is FDA-approved in 35+ countries (under the name Zadaxin) for hepatitis B/C, vaccine enhancement, and as an immune adjuvant in immunocompromised patients. In bodybuilding and anti-aging, it is prized for dramatically strengthening immune function and accelerating recovery.
How It Works
Tα1 acts directly on immune cells by upregulating T-cell maturation, increasing cytokine production (IL-2, IFN-γ), stimulating dendritic cell activity, and enhancing NK-cell function. It restores immune balance without over-stimulation, making it uniquely effective during harsh contest prep, prolonged cycles, or periods of high stress and suppressed immunity.
Thymosin Alpha-1 Benefits
- Powerful Immune Restoration: Prevents illness during calorie deficits and intense training
- Faster Recovery: Reduces inflammation and speeds tissue repair
- Anti-Viral & Anti-Bacterial: Clinically proven against hepatitis, HIV co-infection, and respiratory pathogens
- Vaccine/Immune Response Booster: Increases antibody production
- Long-Term Health Protection: Used year-round by elite athletes on heavy cycles
Who It's For
Competitive bodybuilders in deep contest prep, athletes on long/heavy anabolic cycles, individuals with chronically low immunity, or anyone over 35 looking to maintain robust immune function while pushing training and pharmacological limits.
How to Use
Reconstitution: Add 2 ml bacteriostatic water → 5 mg/ml
Standard Protocol: 1.6–3.2 mg (0.32–0.64 ml) subcutaneously 2–3 times per week
Contest Prep / Immune Crash: 3.2–5 mg twice weekly for 4–6 weeks
Maintenance: 1.6 mg twice weekly indefinitely
Best timing: Evening injections, away from training
Stacking Suggestions
- Contest Immunity Shield: Thymosin Alpha-1 + BPC-157 + TB-500
- Year-Round Defense: Thymosin Alpha-1 + MK-677 + low-dose testosterone
- Post-Viral Recovery: Thymosin Alpha-1 + Selank + high-dose vitamin D
Side Effects
- Extremely rare — generally considered one of the safest peptides
- Occasional mild redness at injection site
- No hormonal suppression or HPTA interference
Post Cycle Therapy (PCT)
Not required — Thymosin Alpha-1 does not suppress natural hormone production and can be used during and after any cycle.
Frequently Asked Questions
Why do pro bodybuilders use Thymosin Alpha-1 in prep?
It prevents the near-inevitable immune crash that occurs when calories, drugs, and training volume are at their extreme — keeping athletes healthy all the way to the stage.
How long can I run Thymosin Alpha-1?
Clinical studies and real-world use show it is safe and effective for continuous administration — many athletes use it 52 weeks/year at maintenance doses.
Will Thymosin Alpha-1 make me test positive?
No — it is not a banned anabolic agent and is not detected in standard doping controls.
Can I use it during an infection?
Yes — it is one of the few peptides with proven therapeutic effects against active viral and bacterial infections.
Is Dragon Pharma Thymosin Alpha-1 the same as Zadaxin?
Yes — identical 28-amino-acid sequence, produced under full GMP conditions with >99% purity.
