Frequently Asked Questions

TB-500 solo vs. the P3 Recovery stack?

P3 pairs TB-500 with BPC-157 for most soft-tissue goals. Solo TB-500 is typically for a specific clinical situation your clinician has identified.

Start with labs.

We won't prescribe TB-500 without reviewing your baseline labs first. The $149 Peptide Readiness Panel covers what your clinician needs to write a safe, individualised prescription.
