TB-500 dosage calculator
TB-500 has a short serum half-life but a long tissue residence, which is why protocols front-load a couple of large weekly doses rather than dosing daily. A 2mg draw off a 5mg/2mL vial lands at a clean 0.8mL.

How to reconstitute TB-500
STEP 1
Add bacteriostatic water
Trickle 2mL of BAC water down the inside wall of the 5mg vial. That gives a 2.50 mg/mL solution.
STEP 2
Swirl, do not shake
Rotate gently until fully dissolved. Shaking shears the peptide.
STEP 3
Draw your 2000mcg dose
Pull to 80.0 IU (0.800 mL). One 5mg vial yields about 2 doses.
STEP 4
Refrigerate between uses
Store the reconstituted vial at 2-8°C and use within a few weeks.
TB-500 dosing questions
How do I reconstitute TB-500?+
Add 2mL of bacteriostatic water to a 5mg TB-500 vial. That produces a 2.50 mg/mL (2500 mcg/mL) solution. For a 2000mcg dose you then draw 0.800 mL.
How many units of TB-500 do I draw for a 2000mcg dose?+
On a U-100 insulin syringe, draw to 80.0 units (0.800 mL). Adjust the inputs above if your vial or water volume differs.
How many TB-500 doses are in one vial?+
A 5mg vial dosed at 2000mcg gives about 2 doses.
What is TB-500's half-life?+
TB-500 has a half-life of ~2-3 hours (serum). A typical protocol is 2-2.5mg twice weekly (loading), then weekly. TB-500 has a short serum half-life but a long tissue residence, which is why protocols front-load a couple of large weekly doses rather than dosing daily. A 2mg draw off a 5mg/2mL vial lands at a clean 0.8mL.
