Product overview
Generic Peptides TB 500 - 2, 5 and 10 mg Vials
Generic Peptides TB 500 is a synthetic fragment of thymosin beta 4 sold as a lyophilized research powder in 2 mg, 5 mg and 10 mg vials. The shop lists the active substance as thymosin beta 4, and the material itself is the N-acetylated heptapeptide Ac-LKKTETQ, the segment of residues 17 to 23 of the natural protein. It is normally read next to a repair peptide such as BPC-157.
- Three vial sizes - 2, 5 and 10 mg
- Ac-LKKTETQ fragment of thymosin beta 4
- Lyophilized powder - needs a solvent
- GMP-made, HPLC-verified, COA on file
Variant Comparison
All three vials hold the same peptide, so the choice is how much material one series needs.
| Variant | Dosage | Form and quantity | Best use |
|---|---|---|---|
| TB 500 2 mg | 2 mg | Lyophilized vial | Short runs |
| TB 500 5 mg | 5 mg | Lyophilized vial | Standard series |
| TB 500 10 mg | 10 mg | Lyophilized vial | Extended series |
The 5 mg and 10 mg vials also carry a U.S. domestic option while the 2 mg vial is international only. A growth factor such as IGF-1 LR3 is a common separate arm when a tissue read-out and a growth signal are run together.
How TB 500 Works
Thymosin beta 4 is an actin-binding protein, reported as 43 or 44 amino acids depending on the source, and the Ac-LKKTETQ fragment carries its actin-binding part. Laboratory models describe cell migration and soft tissue work around this interaction. The claims attached to TB 500, including faster wound healing and lower inflammation, have no human trial behind them, and one secondary source raises an unconfirmed question about tumour development. Human half-life is not established.
Reconstitution & Storage
The powder is dissolved with sterile or bacteriostatic water, which is not in the pack, added down the vial wall and swirled rather than shaken. Divide the amount on the label by the millilitres added: 5 mg in 2 mL gives 2.5 mg per mL. Keep the lyophilized vial at 2-8 C or -20 C, protected from light, and the mixed solution at 2-8 C for about four weeks.
Dosage & Administration
No human dose is stated here and the vial is not a medicine. TB 500 has no approved indication and no established human half-life, so nothing on this page is a dosing guide. Thymosin beta 4 and its derivatives sit in WADA class S2.3 and are banned in sport at all times. Thymosin Alpha-1 comes from the same family but is studied in a different setting, and Somatropin acts on another axis entirely.

Consult a qualified healthcare professional before use. TB 500 is supplied as a lyophilized powder and stays stable when the vial is kept cold and dry.

FAQ
Before you ask
Questions, answered
TB 500 is a synthetic heptapeptide with the sequence Ac-LKKTETQ, the N-acetylated segment of residues 17 to 23 of thymosin beta 4. Its CAS number is 885340-08-9, its PubChem identifier is 62707662 and its mass is about 889 g/mol. It is supplied as a research material and has no approved medical use anywhere.
Thymosin beta 4 is the natural protein, an actin-binding molecule that sources describe as either 43 or 44 amino acids with a mass near 5 kDa. TB 500 is only a short piece of it, seven amino acids long, carrying the actin-binding end of the chain. The catalog entry lists the active substance as thymosin beta 4 because that is how the material is labelled on the shop page.
Sterile or bacteriostatic water is added down the wall of the vial and the contents are swirled, not shaken, until the powder has dissolved; the solvent is not included in the pack. Concentration is the amount on the label divided by the millilitres added, so a 5 mg vial plus 2 mL gives 2.5 mg per mL and a 10 mg vial plus 2 mL gives 5 mg per mL.
The lyophilized vial is kept at 2-8 C or -20 C, protected from light and moisture, and it should reach room temperature before opening. The mixed solution is kept at 2-8 C for about four weeks, without repeated freeze and thaw cycles. A solution that has turned cloudy or shows particles is discarded rather than used in an experiment.
There is no human safety data for TB 500, because the peptide has never gone through human trials, so a side effect profile cannot be given. Injection site reactions are the usual local effect in this class. A secondary source raises a concern about high levels and tumour development, and that concern has not been confirmed in human work. Long term effects and any interaction profile remain unknown.
Yes. Thymosin beta 4 and its derivatives, with TB 500 named directly, appear in class S2.3, growth factors and growth factor modulators, of the WADA Prohibited List. Substances in that class are prohibited at all times, in and out of competition. Metabolites of the peptide have been measured in horse urine and plasma in veterinary work, so detection is possible in principle.
Yes, all three vial sizes are in stock on this page and can be ordered directly. The 2 mg, 5 mg and 10 mg vials ship internationally, and the 5 mg and 10 mg vials also have a U.S. domestic option. International shipping is about USD 35, orders are processed in one to two business days and transit runs four to ten days depending on the destination country.
