Frequently asked questions
What is a Certificate of Analysis?
A Certificate of Analysis (COA) is a third-party-verified document confirming a product's identity, purity, and potency. Every MedVinci order includes a lot-specific COA showing HPLC purity and mass-spec identity confirmation. See our guide to how to read a peptide COA.
What does "research use only" mean?
"Research use only" (RUO) means a product is sold for in vitro laboratory work and cannot be used in humans, animals, food, or cosmetics. It is the legal and ethical standard for unscheduled research compounds not approved by the FDA for any therapeutic indication.
How are MedVinci products tested?
Every lot is tested by an independent third-party lab using HPLC for purity and mass spectrometry for identity confirmation. Results are published on the lot-specific Certificate of Analysis shipped with your order and searchable in our COA directory. Read more on third-party vs vendor-only COA verification.
What is TB-500?
TB-500 is the synthetic form of Thymosin Beta-4, a 43-amino-acid peptide present in nearly all mammalian cells. It is the principal G-actin-sequestering peptide involved in cytoskeletal regulation. It is supplied as a lyophilized powder for laboratory research.
