TB-500 Dosage: Complete Guide to Protocols, Dosing & Administration
TB-500 dosing follows a structured two-phase approach: a loading phase to saturate tissue and establish therapeutic peptide levels, followed by a lower-dose maintenance phase to sustain those levels. Unlike weekly peptides such as retatrutide or daily peptides such as sermorelin, TB-500 protocols often use twice-weekly injections during the loading phase, transitioning to once-weekly or every-other-week maintenance.
- TB-500 uses a two-phase protocol: loading phase (higher dose, 2x weekly for 4–6 weeks) followed by maintenance phase (lower dose, once weekly or every 2 weeks)
- Typical loading dose is 2–2.5 mg twice weekly; typical maintenance dose is 2–2.5 mg once weekly or every other week
- TB-500 can be administered subcutaneously or intramuscularly — subcutaneous is most common for self-administration
- Reconstituted TB-500 should be clear and colorless; never shake the vial — roll gently
- TB-500 stacks well with BPC-157 for enhanced musculoskeletal recovery and with PRP, physical therapy, and other adjunct therapies
- All protocols are physician-supervised and personalized based on injury type, severity, and treatment goals
- Lab monitoring is recommended at baseline and during extended protocols
The Two-Phase Dosing Protocol
TB-500 is not a medication you take once and assess. It requires adequate tissue saturation during the loading phase before the maintenance phase sustains the healing signal.
Loading Phase: 2–2.5 mg administered twice weekly (e.g., Monday and Thursday) for 4–6 weeks. This initial phase establishes therapeutic peptide levels in tissue and initiates the actin regulation, inflammation reduction, and angiogenesis promotion that drive healing.
Maintenance Phase: After loading is complete, the dose drops to 2–2.5 mg once weekly or every two weeks. Some patients cycle off entirely for 4–6 weeks after a full maintenance course and restart with a loading phase if injury recurs or symptoms return.
Your physician determines the appropriate protocol based on the nature and severity of your injury, your response during the loading phase, and your overall treatment goals. For the complete dosing protocol with specific timing and volume guidance, see TB-500 Dosing Protocols & Calculator Guide →.
Syringe Calculations & Reconstitution
TB-500 arrives as lyophilized powder requiring reconstitution with bacteriostatic water before use. The standard syringe calculation formula using a U-100 insulin syringe: divide your desired dose in mg by the concentration in mg/ml, then multiply by 100.
Key reconstitution rules: bacteriostatic water only — not sterile water or saline. Never shake — roll gently to dissolve. Solution should be clear and colorless; discard if cloudy. Refrigerate immediately after reconstitution and use within 28–30 days. Never freeze reconstituted TB-500.
For complete concentration reference tables, step-by-step reconstitution, and worked examples for every common vial configuration, see the TB-500 Dosage Calculator →.
Injection Technique
TB-500 is administered subcutaneously (preferred for self-administration) or intramuscularly. Subcutaneous injection is into the fatty tissue just beneath the skin at the abdomen, thigh, or outer upper arm. Rotate injection sites with every dose to prevent localized tissue reactions.
Subcutaneous technique: clean the site with an alcohol swab, allow to dry, pinch a fold of skin, insert needle at 45–90°, inject slowly and steadily, remove and apply gentle pressure without rubbing, dispose of needle in a sharps container immediately.
Intramuscular technique (when physician-directed): typically into the vastus lateralis (outer thigh) or deltoid using a longer needle gauge. Your physician will specify when IM administration is clinically preferred.

What to Monitor During Treatment
Your physician will typically check baseline inflammatory markers, liver and kidney function, and CBC before starting. During treatment, weight, injury progression, and any adverse reactions are monitored at each check-in.

Frequently Asked Questions
What is the standard loading dose?
2–2.5 mg twice weekly for 4–6 weeks. Your physician may adjust based on injury severity and your response during the first two weeks.
Can I inject TB-500 near the injury site?
TB-500 is a systemic peptide — it does not need to be injected at the injury site to be effective. Standard subcutaneous injection sites deliver therapeutic levels throughout the body via circulation. Physician-directed IM protocols near injury sites are sometimes used, but are not required.
Can I use TB-500 indefinitely?
Most protocols cycle — loading phase, maintenance phase, then a break before reassessment. Long-term continuous use is not standard practice. Your physician determines the appropriate duration and cycling schedule.
What if I miss a dose?
Take the missed dose as soon as you remember. If it's close to your next scheduled dose, skip the missed one and continue normally. Never double dose.
