Questions
TB-500 questions
Is TB-500 third-party tested, and does it include a certificate of analysis?
Every lot of TB-500 is assayed by reverse-phase HPLC-UV for purity and confirmed by LC-MS, then ships with a certificate of analysis matched to the batch number printed on the vial. Look up any batch on the Verify COA page before you buy, and independent third-party verification of any lot is available on request.
How does the TB-500 subscription work, and can I cancel?
Subscribing takes 30% off TB-500 on every order, not only the first. Your card is charged today for this order, then every 30 days for each following shipment at the same 30%-off rate, and shipping is free every time. There is no minimum number of orders and no fee to stop: cancel from the Track order page with your order number and email, no account required, and nothing further is billed.
How is TB-500 shipped and packaged?
Orders ship in plain, unmarked packaging from within the US, fully tracked, with next business day dispatch once payment clears. Card payments are processed by Stripe and show a neutral name on your statement. If a package is lost, held, damaged or wrong, our delivery guarantee reships or refunds it, no dispute needed.
How is TB-500 stored and reconstituted?
TB-500 is supplied lyophilized, generally kept frozen before reconstitution and refrigerated once in solution, within its stability window. Reconstitute with bacteriostatic water in a laboratory setting; our free reconstitution calculator works out the concentration and syringe draw for any vial size.
