How to actually track Thymosin Alpha-1 side effects

Thymosin Alpha-1 is most useful to track via the immune outcome you are targeting (frequency of illness, recovery) plus a CBC/WBC and hs-CRP at baseline and end-of-cycle. If you have an autoimmune condition, that tracking matters more - and the compound is a provider conversation first.
