TB-500 + Thymosin Alpha-1 Stack Protocol Guide — Path To Peptides

Complete TB-500 + Thymosin Alpha-1 systemic healing and immune support stack with dosing, synergy timeline, and immune modulation protocol.

Context first

Study findings do not automatically establish clinical benefit, safety, dosing, or suitability for an individual.

Protocol Overview

Synergy & Mechanism

TB-500 Mechanism

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.

Combined Dosing Protocol

Standard

TB-500 750mcg 3x/week

TA1 1.6mg 2x/week

TB: M/W/F, TA1: Tu/Th

8-12 weeks

Loading

TB-500 2mg 2x/week (wk1-4) then 750mcg

TA1 1.6mg 3x/week

Alternating days

12 weeks

Maintenance

TB-500 750mcg 2x/week

TA1 1.6mg 1x/week

M/Th

Ongoing

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

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

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.
