Mechanism & published research
Regulates actin polymerization; studied for cell migration, angiogenesis, and wound repair.
Promoted cell migration and repair in preclinical tissue models.
Honest note on evidence: Evidence is largely preclinical.
Descriptions summarize existing published research and are not claims about outcomes from use. Every citation states its study type and population.
How it compares
| Versus | Attribute | Note |
|---|---|---|
| BPC-157 | Mechanism | Different pathway; commonly co-studied for recovery. |
Reconstitution
Concentration math only: add bacteriostatic water to the vial and the resulting concentration is shown below. This is not usage guidance.
| Vial | Bacteriostatic water | Concentration |
|---|---|---|
| 5 mg | 2 mL | 2.5 mg/mL |
| 10 mg | 2 mL | 5 mg/mL |
Storage & stability
| State | Temperature | Duration |
|---|---|---|
| Lyophilized (unopened) | -20°C | 24 months |
| Reconstituted | 2–8°C | up to 4 weeks |
Reviews
Reviews are collected post-delivery and screened to exclude any human-use or dosing-outcome claims before publication. They speak to product quality, shipping, and COA accuracy.
“Dissolved completely with zero cloudiness and the HPLC purity matched the label. Clean documentation.”
“Reconstituted cleanly with no cloudiness, and the COA endotoxin pass was included in the PDF.”
“Second lot I've ordered and both certificates verified independently. That repeatability is why I stay.”
Product FAQ
Is TB-500 the same as Thymosin β4?+
TB-500 refers to the active fragment; full-length Thymosin β4 is the parent protein. Sequences differ.
