About this peptide

TB-500 is a synthetic peptide fragment corresponding to the active region of thymosin beta-4 — specifically the LKKTETQ actin-binding sequence. Research applications include soft-tissue repair models, cardiac ischaemia/reperfusion studies, and corneal wound healing assays. Half-life is longer than that of BPC-157, supporting less-frequent dosing schedules in published protocols. Supplied as lyophilized powder under nitrogen; reconstitution at 2–5 mg/mL in sterile water is the most common range. TB-500 is the standard partner for BPC-157 in tendon and ligament repair research — see the bundle pricing on the stack SKU. Each batch is HPLC/LC-MS verified in-house, with the COA bundled and independent third-party re-verification available on request.

Questions about TB-500 20mg — 10-Vial Pack

How is TB-500 20mg — 10-Vial Pack reconstituted?

+

TB-500 20mg — 10-Vial Pack is supplied as lyophilized powder under nitrogen. Typical reconstitution is in sterile or bacteriostatic water; the exact concentration depends on your protocol. Our free reconstitution calculator computes mL per dose and insulin-syringe units from any combination of vial size, water volume, and target dose.

What is the HPLC purity of this batch?

+

Batch TB-2608 of TB-500 20mg — 10-Vial Pack is verified in-house at 99.87% HPLC main-peak purity, with molecular weight confirmed by LC-MS and endotoxin screened by LAL assay. That in-house COA — chromatogram, mass spec trace, and purity call — is bundled with your order as a downloadable PDF. Independent third-party re-verification can be arranged for a specific batch on request; it isn't run by default.

How does QSC ship internationally?

+

All orders ship via DHL, UPS, or FedEx from our China facility, insulated for transit, to 58 countries. Customs duties are prepaid by us (DDP) — no surprise charges on delivery. Estimated transit time is about 10–15 days door to door. Tracking number is emailed when the shipment is scanned by the courier.

What payment methods are accepted?

+

One fully automated, self-serve method, 10% off: "Pay with crypto or card" at checkout takes a direct crypto payment from your own wallet (Bitcoin, Ethereum, USDT, USDC and more) or a normal card payment via our card-to-crypto processing partner — no crypto wallet needed for cards. Wire transfer, PayPal, and Revolut can be arranged by email before you order, at the regular price without the 10% discount. ACH is temporarily paused. Full payment-method details are on the shipping & payment page.

Should TB-500 be paired with other peptides in research protocols?

+

TB-500 is most often studied alongside BPC-157 in tendon, ligament, and soft-tissue repair research. The two work through non-overlapping mechanisms (TB-500 on actin and cell migration; BPC-157 on local growth factor expression) and show additive effects in published repair models. We stock a bundled stack.

Is TB-500 administered locally or systemically in published research?

+

Most published rodent studies in tendon and ligament repair use peri-lesion subcutaneous or intramuscular administration to concentrate the molecule at the repair site. Systemic (sub-Q at a distant site) administration is also reported, particularly for studies probing systemic immune or gut effects. Choice of route depends on the experimental question.
