SKU: TA1-10mg-ER Category:

Thymosin Alpha-1 is a 28-amino acid peptide naturally secreted by the thymus gland with a molecular weight of 3108.35 g/mol. It is among the most studied immunomodulatory peptides in the scientific literature, with research spanning several decades and numerous clinical investigations across multiple disease models.

Its research profile focuses on T-cell activation, dendritic cell maturation, and toll-like receptor signaling, core mechanisms in adaptive and innate immune function. For researchers studying immune competence, chronic immune challenges, or adjuvant models, Thymosin Alpha-1 represents a well-characterized research tool with an extensive published literature base.

Each Etched Research vial contains 10mg of lyophilized powder.

Research at a Glance
  • What it is: A lab-made copy of a natural thymus peptide that researchers use to study how the immune system is signaled and tuned.
  • Researchers have studied it for: Severe sepsis in the ICU, chronic hepatitis B as an add-on to other therapy, and broader immune-modulation research.
  • Evidence level: Real human randomized trials exist here, more than almost anything else in this vault. The catch is the results are mixed, and the largest recent trial came back close to a tie.
  • The short version: Thymosin Alpha-1 is one of the few compounds in this category with actual human trial data behind it. Researchers have run it in sepsis and hepatitis B studies to see how it nudges immune activity. The record is real, but it is mixed, and none of it is a green light to use anything.

Frequently asked questions

Does the product come with instructions?

No. Etched supplies research materials, not use instructions. Each vial ships labeled with the compound name, the labeled amount, and the lot number, and that is what comes in the box. Etched does not provide instructions for use, dosing, or administration for any product, on the label, on this page, or by email. General laboratory handling notes (storage, what bacteriostatic water is) are on the FAQ page at https://etchedresearch.com/faq/. All products are sold for research use only, not for human consumption.

What is the amount of peptide in this product?

The label reads Thymosin Alpha-1 10mg. That figure is the labeled net quantity of Thymosin Alpha-1 in the vial, supplied as lyophilized (freeze-dried) powder. It is not the weight of the vial and not a reconstituted volume. Where a Janoshik Analytical report exists for a lot, the measured result for that lot is on the report itself, and the reports that exist are listed on the COA page at https://etchedresearch.com/coa/. Etched ships lyophilized powder only.

Are additional supplies needed?

Nothing else is included, and Etched sells the lyophilized compound only. Bacteriostatic water is sterile water with a small amount of benzyl alcohol added, used in laboratory settings to reconstitute lyophilized (freeze-dried) research peptides into solution. Etched does not sell bacteriostatic water as a product. It is described here only to explain the reconstitution step in a research context. Any supplies a laboratory setting requires are sourced by the researcher.

How is purity verified?

By a third-party laboratory, named. Janoshik Analytical confirms compound identity by mass spectrometry and measures purity by HPLC. Etched does not use vague "third-party tested" language without naming the lab. The measured number for a tested lot is on that lot's report, not a mood word. Where a Janoshik report exists for a compound it is listed on the COA page at https://etchedresearch.com/coa/, and the report itself carries the lot number and the measured purity. Not every listing has a report posted yet, and the COA page shows which do.

Where do products ship from?

Etched ships within the United States only. There is no international shipping. Orders are fulfilled domestically from within the USA. Orders ship in plain, unmarked packaging with no indication of the contents on the outside.

Who is eligible to purchase?

Etched sells to buyers who are 21 years of age or older and who are qualified researchers, research professionals, or affiliated with a research institution, purchasing for in vitro laboratory research. Every order requires an attestation to those three points at checkout, and the order will not process without it. Research Use Only (RUO) means a product is sold only as a material for laboratory and research use. RUO compounds are not drugs, are not approved by the FDA for human consumption, and are not sold or intended for personal use. Shipping is to United States addresses only.
