About TB-500

TB-500 is a synthetic version of a naturally occurring peptide involved in tissue regeneration and cellular protection. It enhances recovery through increased cell migration and blood vessel formation, promoting accelerated healing and reduced inflammation. Known for supporting muscle repair and joint health, TB-500 is widely used for its regenerative and recovery-enhancing properties.

What are peptides?

Peptides are short chains of amino acids that act as signalling molecules within the body. They are involved in a wide range of biological processes — cellular communication, hormone regulation, tissue repair, immune response, and pathway modulation.

In research settings, peptides are studied for their ability to interact with specific receptor families, modulating cell-signalling pathways, and informing the development of new diagnostic and therapeutic tools.

All peptides sold by Covalent Bio are sold strictly for in-vitro and in-vivo laboratory research use only — and are not approved for human consumption.

Usage & Storage

All peptides are supplied in lyophilized (freeze-dried) form to ensure long-term stability during storage and shipping.

Unreconstituted vials should be stored in a cool, dry place away from direct light. For extended storage (> 30 days), refrigeration at 2–8 °C is recommended; for > 90 days, freeze at −20 °C.

Once reconstituted for research purposes, peptides should be kept refrigerated and handled using sterile laboratory practices. Use within 28 days, or aliquot and freeze at −20 °C.

Shipping & Delivery

All orders are shipped directly from our Canadian fulfillment centre within 24 hours (Monday–Friday). Delivery takes 1–3 business days to major metros, 3–5 days to remote regions, via Canada Post Xpresspost.

Free Xpresspost shipping on orders $300 CAD and up.

Payment Information

We accept Interac e-Transfer (5% discount), all major credit cards via Stripe, and cryptocurrency (8% discount via BTCPay).

Wholesale orders over $2,500 CAD: domestic Canadian wire transfer available.
