What is the half-life of TB-500?

TB-500 has a half-life of ~2 hours, which is why it's typically administered 2x per week (loading), 1x per week (maintenance) for optimal therapeutic effect.

How do I reconstitute TB-500?

Add bacteriostatic water to the peptide vial slowly down the side. Typical reconstitution uses 2-3ml of water for a 5mg vial. Gently swirl, do not shake.
