This is the only thymus supplement I found with polypeptide fractions, a necessary ingredient for thymus supplementation. The balance with the Chinese immunity herb Astragalus was a selling point for me. I trust this company and have had good response to the product.

The product formulation is excellent. I'll give it five stars. All the excipients brings it down to a three. C'mon ET there's no need for all that junk in the capsule. You'll get me back as a customer if you take that stuff out.
