Product overview

Generic Peptides Thymosin Alpha-1 - 2 to 15 mg Lyophilized Vials

Generic Peptides Thymosin Alpha-1 is a synthetic 28 amino acid peptide copying thymosin alpha-1, a fragment made in the thymus. It ships as a lyophilized powder in five vial sizes: 2 mg, 3 mg, 5 mg, 10 mg and 15 mg. The synthetic form is called thymalfasin; the vials here are research material, not an approved human dose. Buy thymosin alpha-1 in the size that fits your study, and run it beside a thymic peptide such as Thymalin when the two are compared.

  • Five vial sizes - 2 mg to 15 mg
  • Lyophilized powder - needs a solvent
  • GMP-manufactured - HPLC-verified per batch, COA on file
  • U.S. domestic and international shipping

Variant Comparison

All five vials hold the same peptide and differ only in amount per vial. Clinical work with thymalfasin uses a fixed weekly dose, so a larger vial covers more injections.

Variant Dosage Form and quantity Best use
Thymosin Alpha-1 2 mg 2 mg Lyophilized vial Pilot
Thymosin Alpha-1 3 mg 3 mg Lyophilized vial Short series
Thymosin Alpha-1 5 mg 5 mg Lyophilized vial Standard runs
Thymosin Alpha-1 10 mg 10 mg Lyophilized vial Long series
Thymosin Alpha-1 15 mg 15 mg Lyophilized vial Extended

The practical difference is how many injections one vial covers: at the 1.6 mg twice-weekly schedule, a 10 mg vial supplies six injections, close to three weeks of a study. An immune design often pairs it with NAD+, and an antioxidant arm adds Glutathione.

How Thymosin Alpha-1 Works

Thymosin alpha-1 is a biological response modifier rather than a direct antiviral. It acts on the maturation and function of T lymphocytes, the cells that coordinate cellular immunity, and on cytokine release. The peptide is 28 amino acids long, about 3,108 daltons. Research areas include chronic viral infection, sepsis and immune support during cancer treatment.

Reconstitution & Storage

Thymosin alpha-1 ships as a powder dissolved with sterile or bacteriostatic water, not part of the pack. Divide the milligrams on the vial by the millilitres added to get mg per mL; a 10 mg vial in 5 mL gives 2 mg/mL. Keep the powder at 2-8 C, away from light. Once mixed, keep it at 2-8 C and use it within 28 to 30 days.

Dosage & Administration

In clinical studies it is given subcutaneously twice a week, with single doses from 0.8 mg to 6.4 mg; the standard hepatitis schedule is 1.6 mg twice weekly for around twelve weeks. No approved dose exists for the research vial, and a long review in hospitalised COVID-19 patients found no reduction in death or length of stay. A related thymic compound is Epitalon.

Stacks

Thymic Peptide Protocol

Thymosin Alpha-1 alongside Thymalin, the two thymic peptides run as separate arms of the same study.

Expected outcome: a comparison of two thymus-derived peptides studied for immune regulation in a matched design.

Immune and Energy Protocol

Thymosin Alpha-1 with NAD+ for a design that touches both immune signalling and cellular energy.

Expected outcome: a two-mechanism model where an immune peptide is paired with a redox coenzyme over the same window.

Longevity Immune Protocol

Thymosin Alpha-1 with Epitalon and 5-Amino-1MQ for a wider longevity research panel.

Expected outcome: a multi-arm study that combines a thymic peptide, a pineal peptide and a metabolic compound.

For laboratory research only. Consult a healthcare professional before handling any peptide. Amounts shown are research references, not recommended human doses.

FAQ

Before you ask

Questions, answered

Thymosin alpha-1 is a synthetic 28 amino acid peptide that copies a fragment of prothymosin alpha made in the thymus. The synthetic version is called thymalfasin and is sold in some countries as Zadaxin. It is classed as a biological response modifier because it works on immune cells rather than attacking a pathogen directly.

It acts on the maturation and function of T lymphocytes, the cells that coordinate cellular immunity, and on the release of cytokines. In animals without a thymus it restored immune function. Research areas include chronic viral infection, sepsis, severe respiratory infection and immune support during cancer treatment.

Add sterile or bacteriostatic water down the wall of the vial and swirl gently until the powder dissolves. Divide the milligrams on the vial by the millilitres added to get mg per mL. A 10 mg vial with 5 mL gives 2 mg/mL, so one unit on a U-100 barrel equals 0.01 mL. Keep the mixed solution at 2-8 C.

Clinical work uses subcutaneous injections twice a week, with single doses reported from 0.8 mg to 6.4 mg. The standard hepatitis schedule is 1.6 mg twice weekly for around twelve weeks. These are study doses, not an approved dose for the research vial, and the card does not set a personal schedule.

Reported effects are usually mild and include redness and discomfort at the injection site, soreness of muscles and joints, and a skin reaction on the hands. A long review in hospitalised COVID-19 patients found no reduction in death or length of stay, which is a fair reminder not to expect guaranteed results.

It is approved in some countries outside the United States, mainly as Zadaxin for chronic hepatitis B and C, but there is no FDA registration. The peptide is not named on the WADA Prohibited List, yet that is not the same as clearance, so athletes should check current rules before any use.

All five vial sizes are listed here as lyophilized research material, with U.S. domestic and international shipping at checkout. Check the import rules that apply where you live before ordering. This listing is for information and is not a substitute for a consultation.
