Trustpilot⚠ Research Use Only
Not for human consumption, veterinary use, or clinical administration. Sold exclusively to qualified laboratories and researchers for in-vitro study.
As one of the most widely referenced actin-binding peptides in the tissue-repair literature, TB-500 gives research groups a well-characterised, single-motif fragment of the Thymosin β-4 parent sequence to work with. Supplied as a 10 mg lyophilised powder at ≥99% verified purity with a per-batch certificate of analysis, each vial is prepared for consistent reconstitution and reproducible in vitro and model work. All myPEPT.eu material is intended strictly for laboratory research use — not for human consumption or injection — and carries no therapeutic or dosing guidance.

Frequently asked
5 questionsHow fast is delivery and which carriers do you use?
Orders placed before 16:00 CET ship the same business day from the Netherlands via DPD or PostNL. EU-wide delivery typically takes 2–5 working days, fully tracked. Every parcel ships in plain, unbranded packaging with no peptide-related markings visible.
Which payment methods do you accept?
We accept iDEAL (Netherlands), Bancontact (Belgium), PayPal, Klarna pay-later, SEPA instant bank transfer, and Visa/Mastercard credit and debit cards. All payments are processed through PCI-DSS-compliant European processors. Bank transfer and card orders ship within 24 hours of payment confirmation.
How do you verify peptide purity?
Every batch is HPLC-tested to 99% purity or higher by an independent third-party laboratory, with identity confirmed by mass spectrometry. The batch-specific Certificate of Analysis is published on every product page and delivered with the order.
Are research peptides legal to buy in the Netherlands and EU?
Yes — when sold and purchased strictly for in-vitro laboratory research. Research peptides on my\PEPT.eu are not approved, marketed or intended for human or veterinary use, medical diagnosis or therapeutic application. By placing an order you confirm research-only intent and accept responsibility for compliance with local regulations.
How should research peptides be stored?
Lyophilized (freeze-dried) peptides keep up to 24 months at −20 °C in a sealed vial. Once reconstituted in bacteriostatic water, store at 2–8 °C and use within 28 days. Avoid repeated freeze-thaw cycles and direct sunlight.
