TB-4 Blood Work Labs: Before vs. After Comparison
ALT (liver enzyme) 10–40 IU/L 15–55 IU/L Mild elevation common; reflects hepatic metabolic activity, not damage Hold protocol if >3× baseline or >120 IU/L AST (liver enzyme) 15–50 IU/L Parallels ALT; disproportionate AST rise suggests muscle breakdown, not liv

- ALT (liver enzyme)
- 10–40 IU/L
- 15–55 IU/L
- Mild elevation common; reflects hepatic metabolic activity, not damage
- Hold protocol if >3× baseline or >120 IU/L
- AST (liver enzyme)
- 15–50 IU/L
- Parallels ALT; disproportionate AST rise suggests muscle breakdown, not liver
- AST:ALT ratio >2 warrants muscle enzyme check (CPK)
- TSH (thyroid)
- 0.4–4.0 mIU/L
- 0.3–4.5 mIU/L
- Mild suppression possible in growth/repair protocols; free T3/T4 matter more
- Investigate if TSH <0.1 or >6.0 with symptoms
- Creatinine (kidney)
- 0.7–1.3 mg/dL
- 0.7–1.4 mg/dL
- Should remain stable; elevation suggests dehydration or renal strain
- eGFR drop >15% from baseline requires hydration assessment
- CRP (inflammation)
- <3.0 mg/L
- <2.0 mg/L
- TB-4 typically reduces baseline inflammation; paradoxical rise is red flag
- CRP >10 mg/L suggests infection or inflammatory flare unrelated to TB-4
- Platelet Count
- 150,000–400,000/μL
- 140,000–420,000/μL
- Minor flux normal; significant drop suggests bone marrow suppression or immune response
- <100,000/μL requires hematology consult before continuing
