Kalpa TB 500 5 mg Thymosin Beta 4 Research Vial for Labs

Kalpa TB 500 5 mg Thymosin Beta 4 Research Vial

Kalpa TB 500 5 mg supplies a synthetic fragment of thymosin beta-4, the actin-binding protein found in almost every cell. The parent protein is 43 amino acids long, and the fragment used in research carries the region that interacts with actin. Laboratory models examine cell migration, blood vessel formation and tissue repair, and no regulator has approved this fragment as a medicine, so it stays a research material supplied under the Kalpa peptide range.

• TB 500 (thymosin beta-4 fragment) - 5 mg per lyophilised vial
• Actin-binding peptide studied in migration and repair models
• Human half-life not established in any source
• GMP-manufactured, HPLC-verified, COA on file per batch

How TB 500 Works

Thymosin beta-4 sequesters actin, the protein that makes up the cell skeleton, and the fragment keeps that interaction. In culture and animal work the result is measured as increased cell migration, more blood vessel formation and faster closure of experimental wounds. Timing is the weakest part of the picture: the human half-life is not established in any source, and vendors state the same. Veterinary work detected the N-acetylated metabolite LKKTETQ in urine and plasma, which is what laboratory monitoring relies on rather than a measured clearance value.

Reconstitution and Storage

A 5 mg vial with 2 ml of bacteriostatic water gives 2.5 mg per ml, so the 2 mg reference amount of vendor protocols measures 0.8 ml, and 1 ml of solvent doubles the concentration and halves that volume. Add the solvent down the vial wall, do not shake, and keep the solution at 2-8 C without freezing. Repair peptides are handled in the same way across the site, so the BPC 157 vial on this line and the TB 500 entry with its own vial sizes are prepared exactly like this one.

Batch Sourcing and Sport Status

Every batch is produced under GMP conditions and checked by independent HPLC, with the Certificate of Analysis held for the batch. Reported effects in research are mainly local to the application site, and no systematic human safety data exist for the fragment. Thymosin beta-4 and its derivatives, TB-500 included, are named in class S2 of the WADA prohibited list and banned at all times, which is the clearest restriction attached to this peptide.
