Zyvex Pharmaceuticals TB-500 5 mg Thymosin Peptide Vial

Zyvex Pharmaceuticals TB-500 5 mg Thymosin Beta-4 Fragment

Zyvex Pharmaceuticals TB-500 is a 5 mg lyophilized vial of a synthetic fragment of thymosin beta-4, the peptide studied for cell migration and soft-tissue repair. Buy TB-500 as a research material, not as a medicine: no human half-life and no human dose have been established for it, and the figures that circulate in gyms come from a vendor protocol rather than from a trial. The vial needs bacteriostatic water before use.

How TB-500 Works

The peptide is described in the literature in terms of actin regulation and cell migration, the biological basis for the repair claims about it. The pharmacokinetic picture is thin: the checked source file records that the human half-life is not established at all, and that detection work has only been done in veterinary studies, where the N-acetylated metabolite LKKTETQ was measured in horse urine and plasma. There is no human detection window to quote. The substance is named on the WADA prohibited list in class S2, so it is off limits for any tested athlete.

Reconstitution & Storage

Add bacteriostatic water down the wall and swirl, do not shake. Divide the milligrams on the vial by the millilitres added: 5 mg with 2 ml reads 2.5 mg/ml, which makes the vendor protocol easy to follow on a U-100 syringe. That protocol is a loading phase of 2.0 to 2.5 mg twice a week for four weeks and then 2.0 to 2.5 mg once a week, so a single 5 mg vial covers roughly one week of loading or two to two and a half weeks of maintenance. It is usually discussed with the locally acting Zyvex BPC-157 vial, and other lines here carry the same peptide as TB-500 2 to 10 mg vials, and the Axiolabs entry as TB 500 5 mg. Keep the powder cold and the mixed solution refrigerated.

Quality & Authenticity

Each batch is produced under GMP conditions and checked by HPLC, with the Certificate of Analysis held for the batch. Store the lyophilized vial at 2-8 C or colder, protected from light, and keep the reconstituted solution refrigerated rather than frozen.
