Healing / Immune Support StackEvidence Grade: B (TB-500) / A (Thymosin Alpha-1)
TB-500 + Thymosin Alpha-1 Stack Protocol Guide
The TB-500 + Thymosin Alpha-1 stack combines systemic tissue healing with powerful immune modulation. TB-500 (Thymosin Beta-4 fragment) promotes cellular migration, reduces inflammation, and facilitates tissue repair throughout the body. Thymosin Alpha-1 (TA1) is an FDA-approved (outside US) immune peptide that enhances T-cell maturation, NK cell activity, and dendritic cell function. Together, these thymic peptides create a comprehensive protocol: TB-500 repairs damaged tissue while TA1 ensures the immune system supports recovery and prevents infection during the healing process.
TB-500 is a fragment of Thymosin Beta-4 that promotes systemic healing through actin sequestration (enabling cellular migration), anti-inflammatory signaling, and angiogenesis. Unlike BPC-157 which excels locally, TB-500 provides whole-body healing support. It allows immune and repair cells to migrate efficiently to damaged sites.
Thymosin Alpha-1 Synergy
TA1 is the master regulator of adaptive immunity, maturing T-cells in the thymus, activating NK cells, and enhancing dendritic cell antigen presentation. During healing, proper immune function prevents opportunistic infections and coordinates the inflammatory-to-resolution transition. TA1 ensures TB-500 healing occurs in an optimally functioning immune environment.

Reconstitution & Preparation
TB-500 Preparation
TB-500 vial: typically 5mg or 10mg lyophilized
5mg vial: reconstitute with 2mL BAC water = 2,500mcg/mL
750mcg dose = 30 units on insulin syringe
Refrigerate, use within 30 days
Thymosin Alpha-1 Preparation
TA1 vial: 1.6mg or 3.2mg lyophilized
1.6mg vial: reconstitute with 1mL BAC water
Use entire vial per dose (1.6mg)
Refrigerate, use within 14 days
Stacking Schedule (AM/PM Timing)
AM Protocol
Mon/Wed/Fri: TB-500 750mcg SubQ, abdomen
Tue/Thu: TA1 1.6mg SubQ, abdomen
Alternate compounds to spread injections
Morning dosing preferred
PM Protocol
No PM injections needed for standard protocol
Both can be taken any time of day
Some prefer TA1 in evening for overnight immune support
Rest days: Saturday and Sunday
Expected Timeline
Week 1-2
TB-500 anti-inflammatory effects begin. TA1 upregulates T-cell and NK cell populations. Early reduction in systemic inflammation.
Week 3-4
TB-500 cellular migration and repair active. TA1 immune optimization measurable in blood work. Improved recovery.
Week 5-8
Full synergy. Systemic healing accelerated with concurrent immune support. Fewer infections, faster wound healing.
Week 9-12
Mature immune remodeling from TA1. Continued tissue maintenance from TB-500. Sustained improvements.
Side Effects & Monitoring
Common Side Effects
Injection site redness (mild)
Mild fatigue during first week (immune activation)
Headache (uncommon)
Flu-like symptoms (TA1, first doses, indicates immune activation)
Precautions
TA1 may flare autoimmune conditions temporarily
Immunosuppressive therapy patients should consult physician
TB-500: avoid if active cancer (angiogenesis concern)
Monitor for immune over-activation signs
Blood Work Recommendations
Panel
Markers
Timing
Immune Panel
CD4/CD8 ratio, NK cell count, lymphocyte subsets
Baseline, Week 6, Week 12
Inflammatory
CRP, ESR, IL-6
Baseline, Week 4, Week 8
Basic
CBC with differential, CMP
Baseline, Week 6
Immune panels should show CD4/CD8 ratio normalization and NK cell count increases. CRP should decrease with TB-500.
