How to Use TB-500: Administration, Reconstitution & Storage (2026)

From Peptidepedia, the trusted peptide wiki.

How to Use / Administration Methods

TB-500 is anecdotally administered via subcutaneous or intramuscular injection, though these routes have not been studied in the literature. Subcutaneous injections are most common and involve injecting into the fatty tissue beneath the skin, often in the abdominal area, thigh, or upper arm.

Administration Guidelines:

  • Start with a lower dose and gradually increase to the target dose to assess tolerance
  • Rotate injection sites regularly to reduce irritation and prevent tissue damage at any single location
  • Injections are typically performed once daily during loading phases or 2–3 times weekly during maintenance
  • Some users inject closer to the injury site, though the peptide's systemic distribution means this may not be necessary
  • Proper sterile technique is essential, including cleaning the injection site with alcohol, using new sterile needles for each injection, and ensuring hands are clean before handling supplies

Reconstitution, Storage & Prep

TB-500 typically comes as a lyophilized (freeze-dried) powder that requires reconstitution before use.

Reconstitution Process:

  1. Allow the vial to reach room temperature
  2. Add bacteriostatic water to the vial containing the lyophilized powder
  3. Inject the water slowly along the inside wall of the vial rather than directly onto the powder
  4. Gently swirl (do not shake vigorously) until the powder is fully dissolved

Common Reconstitution Ratio:

  • 5 mg TB-500 + 5 mL bacteriostatic water = 1 mg/mL (1 mg per 1 mL / 100 units on an insulin syringe)

Storage Guidelines:

  • Unreconstituted: Refrigerated or stored in a cool, dry place; stable at room temperature for short periods
  • Reconstituted: Refrigerated at 2–8°C (36–46°F), stable for 3–4 weeks
  • Never freeze reconstituted peptide solutions
  • Protect from light and heat exposure

Frequently Asked Questions

Most users report initial improvements within 2–4 weeks, with more substantial benefits developing over 4–8 weeks of consistent use. Timelines vary based on injury severity, individual physiology, and dosing protocols.

TB-500 is typically administered via injection (subcutaneous or intramuscular) because peptides are generally degraded in the digestive system when taken orally. Injectable administration ensures the peptide reaches systemic circulation intact.

No. TB-500 is prohibited by WADA and most sports governing bodies both in-competition and out-of-competition. Athletes subject to drug testing should not use this peptide.

While some users prefer injecting near injury sites, TB-500's low molecular weight allows it to travel systemically throughout the body. Research suggests beneficial effects occur regardless of whether the peptide is administered locally or at a distant site.

Unreconstituted TB-500 should be refrigerated or stored in a cool, dry place. Once reconstituted with bacteriostatic water, it must be refrigerated at 2–8°C and used within 3–4 weeks.

Yes, this is one of the most popular peptide combinations, often called the 'Wolverine Stack.' The two peptides work through complementary mechanisms and are commonly used together to support enhanced recovery.
