Enter the amount you want to measure. The vial buttons will highlight which vial strengths create cleaner syringe-unit measurements.
⚠ Use acetic acid — not bacteriostatic water
Thymosin Beta-4 is insoluble or unstable in standard BAC water. Manufacturer protocols require reconstitution in dilute acetic acid (0.1%) — or, for IGF-1 variants, 50 mM acetic acid. Volumes shown below refer to acetic acid, not water.
What amount do you need?
Type the target amount, then choose mg or mcg. Example: 2mg or 500mcg.

What Is It?
Thymosin Beta-4
Full-length thymosin β-4 peptide.
Acetic Acid (0.1%)
A dilute solution of acetic acid (typically 0.1% for most peptides, or 50 mM for IGF-1 variants) used to reconstitute peptides that are insoluble or unstable in standard bacteriostatic water. Thymosin Beta-4 requires an acidic carrier to dissolve fully and remain stable — plain BAC water will not work and may damage the peptide.
How To Mix Thymosin Beta-4
1
Clean
Use alcohol swabs to clean the tops of both vials.
2
Draw Acetic Acid
Draw the selected amount of 0.1% acetic acid.
3
Inject Slowly
Add the liquid slowly down the side of the vial.
4
Swirl Gently
Do not shake. Swirl gently until dissolved.
5
Store Properly
Store as directed and protect from heat and light.
Best Practices & Common Mistakes
Best Practices
Use sterile technique.
Protect from light and heat.
Store refrigerated when appropriate.
Use clean syringe-unit math before measuring.
Common Mistakes
Confusing milligrams with milliliters.
Choosing an option with awkward decimal units.
Using too little liquid for very small measurements.
Shaking the vial aggressively.
Thymosin Beta-4 Storage & Handling
Lyophilized Powder: −20°C (−4°F) for long-term storage (up to 24 months). Refrigeration 2–8°C (36–46°F) for short-term use (up to ~3 months). Original sealed vial in the freezer is safest.
Reconstituted Solution: 2–8°C (36–46°F), use within ~7–14 days. Keep sealed, avoid light, and do not repeat freeze-thaw cycles.
Frequently Asked Questions
It calculates concentration after liquid is added to the vial. The useful output is usually mg/mL or mcg/mL, based on the vial amount and final liquid volume.
Because Thymosin Beta-4 products may be labeled as full-length peptide, TB-500, or a fragment. The calculator can only produce accurate concentration math when the vial amount and compound identity are clearly stated.
The formula stays the same: compound amount divided by final volume. What changes is the molecule being calculated, so TB-500 and full-length Thymosin Beta-4 should not be treated as interchangeable unless the label and COA support that identity.
No. A reconstitution calculator can show how concentrated the solution is after mixing, but it should not provide dosing, timing, injection guidance, or injury-recovery protocols.
Check whether the listing identifies full-length Thymosin Beta-4, TB-500, or another fragment, and whether the vial amount matches the batch documentation. A calculator cannot verify purity, legality, sterility, or suitability for human use.
Practical takeaway: If your real goal is weight or metabolic health, the most useful next step is discussing approved treatment options with a clinician rather than relying on an unapproved compound.
