What is Tirzepatide Tablets 500 mcg × 25?

Tirzepatide is a synthetic 39-amino-acid peptide engineered to activate both the GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 receptors simultaneously. Developed by Eli Lilly and marketed as Mounjaro (T2D) and Zepbound (obesity), tirzepatide produced the most pronounced weight reduction recorded in a Phase 3 incretin trial — 22.5% at 15 mg/week in SURMOUNT-1. The dual agonism profile drives enhanced insulinotropic response and superior body composition outcomes versus single GLP-1 receptor agonists. This oral tablet research format supports investigation into absorption pathways and dose-equivalence research relative to the injectable formulation. Each box contains 25 compressed tablets at 500 mcg per tablet (12.5 mg total active substance).

What purity is verified?

All peptides undergo HPLC analysis with a verified minimum purity of 98%. In practice, most batches reach 99% or higher — the exact value for your specific batch is documented in the Certificate of Analysis (COA) we ship with every order, issued by an independent accredited laboratory. The COA also documents identity and molecular weight. Additional analytical data is available on request.

How should I store this peptide?

Store lyophilized peptides at -20C in a dark, dry environment. In this form, stability is maintained for up to 24 months. After reconstitution, the solution remains stable for 2-4 weeks at 2-8C. Avoid repeated freeze-thaw cycles — aliquot as needed.

Do you provide a Certificate of Analysis?

Yes. Every batch ships with a Certificate of Analysis (COA) from an independent laboratory. The document includes an HPLC chromatogram with purity data and mass spectrometry analysis confirming molecular identity. COA files are available for download on the product page or sent via email with the order.

We ship to Bulgaria (1-2 business days via Econt or Speedy) and all EU member states (3-7 business days via international courier). All shipments are discreetly packaged and temperature-controlled when required.

What is your return policy?

Unopened products in original packaging may be returned within 14 days of receipt for a full refund. Due to the nature of research reagents, opened products cannot be accepted. For defective products, we cover return shipping and issue a full refund.
