Thymosin beta-4 is a naturally occurring peptide investigated in tissue repair. Human topical research includes venous ulcers, where wound healing can be measured directly in a defined patient population.
Research focus: Cell movement, wound closure and tissue repair.

No FDA-approved drug product for this catalog material. Compounding eligibility and approval are separate questions.
Official source ↗The reviewed material does not establish a half-life for this exact material and route.
Half-life describes concentration falling by half. It does not set a dosing interval, a storage period or a drug-test detection window.
Kinetics source ↗No validated common diluent for this exact material was established by the sources reviewed here. Component recipes do not establish blend compatibility.
Bacteriostatic water contains a preservative; plain sterile water does not. Preservative presence does not by itself establish compatibility or a mixed medicine’s usable period.
Preparation source ↗Topical ulcer research does not establish the safety or effectiveness of an injected product. Keep full-length thymosin beta-4 distinct from fragments sold under related names.
Check that a source concerns the same molecule, formulation, route and population. A study of cells, animals or a different product cannot confirm the contents of a vial.
Route-specific clinical wound research; full-length peptide and TB-500 fragments remain distinct.
Other names you may encounter: Tβ4, T beta 4.
Learn to read a study →Each entry keeps one schedule’s amount, frequency and cycle together. Community references, individual reports, clinical trials and prescription products describe different kinds of use. A missing duration or break stays marked as not reported.
Amounts describe mass in mg or mcg. Syringe units describe volume and depend on concentration. A cycle break is different from days off within a week.

The account identifies the TB4 product as full-length thymosin beta-4. These are per-component amounts.
A peptide name and vial mass cannot determine a compatible diluent, powder displacement, storage temperature or discard date. Follow the exact product’s instructions and your pharmacist’s directions.
The injection guide concerns clinician-prescribed subcutaneous medicines; it does not establish that a research-labeled material can be injected.
Start with the formulation: dry powder, prepared solution, pen, tablet and topical product can have different instructions.
General health habits and consistent observations help you assess changes. They are not evidence that a peptide’s effects will be amplified.
A diagnosis, progressive rehabilitation and an appropriate return to activity help put pain and function changes in context.
NIAMS · injury treatment and recovery ↗Use a regular sleep/wake schedule and note changes in sleep quality alongside symptoms or training.
CDC · sleep habits ↗What to record: Record pain, movement, training load and rehabilitation together. Feeling less pain and demonstrating structural healing are different outcomes.
Check dates are editorial references, not a medical review certificate. Labels and evidence can change; consult the linked current document.
Opening values and worked examples illustrate arithmetic; they are not preparation instructions or recommended amounts. Selecting a compound labels the calculation and does not supply a dose or powder-volume correction.

20 mg in an assumed final 1 mL gives 20 mg/mL. An entered 1 mg corresponds to 0.05 mL, or 5 U-100 units, with 20 theoretical portions before losses.

Concentration = mass ÷ final volume
5 mg ÷ 1 mL = 5 mg/mLVolume = target mass ÷ concentration
1 mg ÷ 5 mg/mL = 0.2 mLU-100 markings = volume × 100
0.2 mL × 100 = 20 unitsComplete portions = floor(vial mass ÷ amount per portion).
Displayed numbers are rounded for readability; the calculation uses unrounded values.
