TB-500 vs Thymosin Alpha-1
TB-500 and Thymosin Alpha-1 are both stocked here and are often considered together. This page sets out what differs between them: their class, the sizes and price per milligram, the shape of the published evidence behind each, and where each stands under Canadian law. It does not rank them, because which is appropriate depends on what is being studied.

FAQ
What is the difference between TB-500 and Thymosin Alpha-1?
TB-500 is thymosin beta-4 related peptide (actin-binding); Thymosin Alpha-1 is thymic immunomodulatory peptide. The table above sets out the sizes, the price per milligram, the evidence behind each and their Canadian status.
Which has more published research, TB-500 or Thymosin Alpha-1?
TB-500 has 7 cited studies on its page and Thymosin Alpha-1 has 5. Study count is not quality: the model each one used matters more, and both pages list that for every paper.
Are TB-500 and Thymosin Alpha-1 authorized in Canada?
No Drug Identification Number; named in a Health Canada advisory for TB-500. No Drug Identification Number; named in a Health Canada advisory for Thymosin Alpha-1. Health Canada authorizes a drug by issuing an eight-digit Drug Identification Number, and most research peptides have none.
Can TB-500 and Thymosin Alpha-1 be used together?
No published study has tested them in combination, so there is no evidence about what a pairing does. We supply both for laboratory research and make no claim about using them together.
