Frequently Asked Questions
What is the CAS number for TB-500?
77591-33-4.
Is TB-500 the same as Thymosin Beta-4?
No. Thymosin Beta-4 is the full 43-amino-acid protein; TB-500 is a shorter synthetic fragment of its active region.
Should I choose the 5mg or 10mg vial?
Both are the same material; vial size is a matter of research scale and storage preference.
Is TB-500 available premixed with BPC-157?
The BPC-157 + TB-500 Blend is a separate listing supplied in one premixed vial. The BPC-157 + TB-500 Research Duo supplies separate vials.
How is TB-500 stored?
Refer to the documentation applicable to the supplied product. Contact Ascend Research if you need clarification.
Where does Ascend Research ship from?
