How much BAC water should I use for a 5 mg TB-500 vial?

The most common and practical amount is 2 ml of BAC water, giving a concentration of 2.5 mg/ml for easy and accurate small-dose measurement.

What needle size and length are best for TB-500?

27-31 gauge insulin needles with 5/16 inch (8 mm) or 1/2 inch length provide the best balance of comfort and reliable subcutaneous delivery.

How long does reconstituted TB-500 last?

When stored properly in the refrigerator, reconstituted TB-500 remains effective for 28-30 days. Many users finish vials within 2-4 weeks.

Does TB-500 need to be injected near the injury site?

No. TB-500 works systemically through circulation, so abdominal or thigh injections are standard and effective.

What is the loading phase for TB-500?

The loading phase uses 2-2.5 mg injected twice per week for 4-6 weeks to rapidly build tissue levels.

How long should a TB-500 cycle last?

4-6 weeks loading followed by 4-8 weeks maintenance is the standard research cycle length, followed by a break.

Is it safe to stack TB-500 with BPC-157?

Yes. The combination (often called the Wolverine stack) is one of the most researched and commonly used pairings in healing protocols.

What should I do if I miss a dose?

Simply resume your normal schedule at the next planned time. Do not double the next dose.

Common Titration Schedule

Math assumes a standard U-100 insulin syringe (100 units = 1 mL). For research and educational use only — not medical advice.

Worked Example · Loading

10 mg vial + 2 mL BAC water = 5 mg/mL. A 2.5 mg loading dose = 0.5 mL = 50 units on a U-100 syringe (2× per week).

How To Read It

Set your vial size and water volume, pick Loading or Maintenance, tap a protocol, and the tool returns the exact volume, syringe units, and frequency instantly.

01

How to use the calculator

The TB-500 dosage calculator is built exclusively for TB-500 research protocols and accounts for its unique loading + maintenance structure. Five inputs, instant output.

Use the TB-500 dosage calculator every time you dose to ensure precision and repeatability across the loading and maintenance phases.

Reconstituting TB-500, step by step

Materials Needed

Do not shake

Swirl gently until clear. Shaking can damage the peptide. Never use plain sterile water — it lacks preservatives.

The Process

Research-Standard Reconstitution Ratios

03

Injection technique

TB-500 is administered via subcutaneous (SubQ) injection. It works systemically, so there is no need to inject near the injury site. Recommended supplies: 27–31 gauge insulin needle (5/16″ or 1/2″), alcohol swabs, and a sharps container.

Rotate injection sites with every injection to prevent tissue irritation. Because TB-500 works systemically, the location does not need to be near the injury.

For general best practices on safe subcutaneous injections, see the CDC Injection Safety guidelines.

04

How to store TB-500

Before reconstitution

Store the lyophilized powder refrigerated (2–8°C) or frozen for long-term stability. Keep away from light, heat and moisture. Unopened vials stay stable for many months.

After reconstitution

Refrigerate at 2–8°C immediately and protect from light. Use within 28–30 days for optimal potency. Discard if the solution turns cloudy, discolored, or develops particles.

Never leave reconstituted TB-500 at room temperature for extended periods.

05

Recommended dosage protocols

All protocols use conservative starting numbers derived from consistent multi-source research data and community consensus. Tap any protocol in the calculator to see the exact draw.

Cycle length: a typical full cycle runs 4–6 weeks loading + 4–8 weeks maintenance, followed by a 4+ week break.
