Thymosin Alpha Pen

800.00 AED — In stock

Thymosin Alpha-1 (Tα1) is a naturally occurring peptide produced by the thymus gland, first isolated and characterised in the 1970s. It plays a fundamental role in the maturation and activity of T-cells - the immune system's primary defence and regulatory cells — and is one of the most studied immunomodulatory peptides in clinical and research settings worldwide. What Thymosin Alpha-1 is studied for: Immune system modulation - Tα1 is studied for its ability to enhance T-cell differentiation, maturation, and activity, supporting a more coordinated and effective immune response Immune resilience - Research highlights its role in restoring immune function in states of suppression or dysregulation, making it a focus of study in both chronic illness and general immune optimisation Anti-inflammatory regulation - Studied for its role in modulating inflammatory signalling pathways, supporting a balanced immune response without immunosuppression Antiviral and antimicrobial defence - One of the most researched peptides in the context of immune defence, with published studies across multiple viral and bacterial models Longevity and immune aging - Explored in the context of immunosenescence - the gradual decline of immune function with age - and its potential role in maintaining immune performance over time Thymosin Alpha-1 is recognised across international research and clinical communities as a benchmark immunomodulatory compound.

What is Thymosin Alpha Pen?

Thymosin alpha-1 is a 28-amino-acid peptide first isolated from thymosin fraction 5, an extract of calf thymus. It is naturally cut from a larger protein called prothymosin alpha. The synthetic form, thymalfasin, is identical to the natural peptide and carries an acetyl group at its start.

Thymosin alpha-1 is thought to act as an immune modulator. Research suggests it interacts with toll-like receptors on immune cells. It has been studied for effects on T cell maturation and on the balance between immune activation and tolerance.

Also known as: Thymalfasin, Tα1, TA1, Zadaxin

What the research covers

Thymosin alpha-1 has a larger human evidence base than many peptides. It has been studied in clinical trials in chronic hepatitis B and C, as a vaccine adjuvant, in sepsis and alongside cancer treatment. Results vary by condition, and some meta-analyses report possible benefit while noting study quality concerns. Its use in healthy ageing has been studied far less, and early research in this area is largely theoretical. Thymalfasin is approved under the brand name Zadaxin in a number of countries, mainly for chronic hepatitis B and C. It is not approved by the US FDA.

Frequently asked questions

Is this the same as Zadaxin?

Zadaxin is the branded form of thymalfasin, approved in some countries for chronic hepatitis B and C. Our product is a compounded preparation of the same peptide, prescribed by our GP. It is not the branded medicine.

How is thymosin alpha-1 different from Thymalin?

Thymosin alpha-1 is one defined 28-amino-acid peptide. Thymalin is a mixture of short thymus-derived peptides. Both have been studied for immune function.

Which formats are available and how do I store them?

We supply thymosin alpha-1 as a pen, cartridge or vial. Keep pens, cartridges and reconstituted vials refrigerated at 2-8°C. Follow the storage instructions on your pharmacy label.

Are there side effects?

Side effects can occur. Your GP will review your health, medication and, where relevant, blood results before prescribing, and you should report anything unexpected.

How much will I take?

Your dose is set by our licensed GP following a consultation, and printed on your pharmacy label.
