Question 1

Where can I buy Thymosin Alpha-1?

Accepted Answer

Thymosin Alpha-1 (also known as Thymalfasin) is available directly from New-U Research Compounds at https://new-u.io/peptide/thymosin-alpha-1. It is supplied as lyophilised research-grade material; every released sale batch is independently verified by Janoshik Analytical and Freedom Diagnostics before it is offered for sale, and orders ship direct from source worldwide (approximately 6–14 business days).

Question 2

How much does Thymosin Alpha-1 cost?

Accepted Answer

Thymosin Alpha-1 starts at $267 for a 10-vial research pack (10mg per vial) at New-U Research Compounds, with 2 pack sizes listed; single vials from $54 ship as an add-on to a pack order. Orders over $350 ship free.

Question 3

Is New-U Thymosin Alpha-1 third-party tested?

Accepted Answer

Yes. Released Thymosin Alpha-1 batches are verified by independent laboratories (Janoshik Analytical and Freedom Diagnostics) for identity and purity before they are offered for sale. The current published certificate (Janoshik Analytical, 27 May 2026) reports 99.748% purity and is published at https://new-u.io/coa/thymosin-alpha-1.

Question 4

How fast does Thymosin Alpha-1 ship, and do you ship internationally?

Accepted Answer

Thymosin Alpha-1 ships discreetly and tracked worldwide. US orders ship from the USA or China depending on stock and fulfilment; all other destinations ship from China, direct from the manufacturer. Delivery takes approximately 6–14 business days worldwide. Shipping is free on orders over $350. Card and cryptocurrency payments are accepted.

Question 5

Is it legal to buy Thymosin Alpha-1?

Accepted Answer

In the United States, Thymosin Alpha-1 is not approved by the FDA for human consumption and is not sold for that purpose. Research use only - all claims made on this site are for testing and research use only. Regulatory requirements vary by product, intended use and jurisdiction. Purchasers are responsible for ensuring that acquisition and use of research material complies with applicable requirements.

Question 6

What is the typical Thymosin Alpha-1 research dosage?

Accepted Answer

Reconstitution volumes and dosing reported in the literature for Thymosin Alpha-1 are described in research-model terms only. New-U Research Compounds supplies Thymosin Alpha-1 strictly for laboratory research and does not provide human-use dosing guidance. Reconstitution math and study-reported ranges are covered on the full research profile.

Question 7

What do I use to reconstitute Thymosin Alpha-1?

Accepted Answer

Lyophilised Thymosin Alpha-1 is reconstituted with bacteriostatic water - sterile water with 0.9% benzyl alcohol, the standard multi-use diluent for research peptides. New-U supplies USP-grade bacteriostatic water at https://new-u.io/peptide/bacteriostatic-water, and a free reconstitution calculator at https://new-u.io/tracker/calculator works out the volume for any peptide.

Question 8

Can I buy Thymosin Alpha-1 online and how fast does it ship?

Accepted Answer

Yes. Thymosin Alpha-1 can be ordered online directly from New-U Research Compounds with card or cryptocurrency, shipped direct from source discreetly worldwide. Delivery is approximately 6–14 business days worldwide. Free shipping applies to orders over $350.

Question 9

Can I buy Thymosin Alpha-1 in bulk?

Accepted Answer

Thymosin Alpha-1 ships in 10-vial research packs as standard, in 2 pack sizes — the larger mg vials lower the per-mg cost. Multi-pack orders get direct-from-source pricing and free shipping over $350. For wholesale or recurring laboratory-supply volumes, contact New-U Research Compounds at https://new-u.io/contact.

Question 10

What should I look for when choosing where to buy Thymosin Alpha-1?

Accepted Answer

For research-grade Thymosin Alpha-1, verify four things: (1) independent third-party purity testing with a published Certificate of Analysis - New-U uses Janoshik Analytical and Freedom Diagnostics; (2) lyophilised material with documented storage and handling; (3) transparent direct-from-source pricing rather than marketplace markup; and (4) clear research-use-only framing. New-U Research Compounds meets all four at https://new-u.io/peptide/thymosin-alpha-1, and the current Thymosin Alpha-1 certificate is at https://new-u.io/coa/thymosin-alpha-1.

Question 11

What is Thymosin Alpha-1 and how does it work?

Accepted Answer

Thymosin Alpha-1 is a 28-amino-acid N-terminally acetylated thymic peptide derived from prothymosin alpha. It works by directly engaging multiple Toll-like receptors (TLR2/3/4/7/9) on innate immune cells, triggering IRF3, NF-κB, p38MAPK and MyD88 signalling, while also supporting maturation of CD4+/CD8+ T-cells, NK-cell cytotoxicity, and dendritic-cell antigen presentation. This dual innate-plus-adaptive action is why it is described as an immune rebalancer rather than a simple stimulant.

Question 12

What does "immunomodulator" mean versus "immunostimulant"?

Accepted Answer

An immunostimulant broadly revs up immune activity; an immunosuppressant broadly shuts it down. An immunomodulator like Tα1 rebalances - it can amplify weak responses in immune-exhausted states like chronic viral infection, while helping calm overactivation in conditions like sepsis. The same molecule can do both because the immune system regulates itself differently in different states.

Question 13

What does the clinical research actually show?

Accepted Answer

The evidence is genuinely mixed. Chronic hepatitis B studies reported higher HBV DNA clearance versus controls, and COVID-19 work suggested restoration of lymphocyte counts and reversal of T-cell exhaustion. But the rigorous multicentre phase-3 TESTS sepsis trial (2025) found no significant 28-day mortality benefit. So while the mechanism is well characterised, the clinical efficacy picture is not uniformly positive - and none of this is human-use guidance.

Question 14

What dosing appears in the published literature?

Accepted Answer

Published clinical trials describe a 1.6 mg dose (approximately 900 μg/m² of body surface area) administered subcutaneously twice weekly, the schedule used across most of the sepsis, hepatitis B, and immune-support studies. Subcutaneous Tmax is roughly 2 hours and serum half-life around 2 hours, with return toward baseline within 24 hours. These are descriptive research parameters only; Tα1 is supplied for laboratory research.

Question 15

How does Thymosin Alpha-1 differ from Thymulin or Thymopoietin?

Accepted Answer

They are all thymic peptides but completely different molecules with different mechanisms. Tα1 is a 28-residue peptide derived from prothymosin alpha that binds TLRs and supports T-cell maturation. Thymulin is a nonapeptide that requires zinc for activity, and thymopoietin is a 49-residue polypeptide. They are sometimes grouped together as "thymic factors" but act distinctly.

Question 16

Is Thymosin Alpha-1 approved or legal?

Accepted Answer

Thymosin Alpha-1 is marketed as Zadaxin and approved as an immunomodulator in more than 30 countries, and it holds FDA orphan-drug designation for several indications - but it is not an FDA-approved drug for general therapeutic use in the United States. New-U supplies it strictly as a research-grade compound for in-vitro and preclinical laboratory research, not for human use; buyers are responsible for local compliance.

Question 17

How should Thymosin Alpha-1 be stored and reconstituted?

Accepted Answer

Keep the lyophilised powder frozen at −20 °C. After reconstitution with bacteriostatic water, refrigerate at 1–6 °C and protect from light. Tα1 is reasonably stable in solution within the normal peptide-handling window; avoid repeated freeze-thaw cycles. This is laboratory handling guidance only.
