British Dragon TB-500 5 mg Thymosin Beta-4 Peptide Vial

British Dragon TB-500 5 mg Research Vial

British Dragon TB-500 is a synthetic peptide: the acetylated fragment Ac-LKKTETQ of the protein thymosin beta-4, supplied as a research powder in a 5 mg vial. It is studied for connective tissue and cell migration in laboratory models rather than as a hormone, and no regulator has approved it for human use. It is most often ordered beside BPC-157 when the design covers tissue repair.

• 5 mg of the thymosin beta-4 fragment per vial
• Lyophilized research powder - needs a solvent before use
• GMP-manufactured - HPLC-verified per batch, COA on file
• International shipping with discreet plain packaging

How TB-500 Works

Thymosin beta-4 is a small actin-binding protein found in most cells, and TB-500 is the short active fragment of it. The research literature describes it as promoting cell migration, blood vessel formation and the organisation of the actin cytoskeleton, which is the mechanism generally used to explain the connective tissue and wound repair read-outs seen in animal models. The limits of that evidence matter: no half-life has been established for TB-500, and the sources consulted state that absence of data openly rather than filling it in. The repair side of the catalogue also includes GHK-CU for collagen work. In sport TB-500 is not a grey area: thymosin beta-4 and its derivatives are named in WADA class S2 and prohibited at all times.

Reconstitution & Storage

Add bacteriostatic water down the wall of the vial and swirl gently instead of shaking it, because the peptide chain is fragile. A 5 mg vial with 2 ml of solvent gives 2.5 mg per ml, which is the arithmetic used in the reconstitution examples published for the neighbouring peptide lines. Keep the powder cold and dry before use, hold the dissolved solution at 2-8 C, do not freeze it, and avoid repeated freeze and thaw cycles. Human pharmacokinetics are not established, so the amounts quoted by suppliers are research references only. A separate solvent is listed as Bacteriostatic Water, and the same fragment from another line is described on the Axiolabs TB 500 page.
