Huberman used BPC-157 for an L5 disc compression from deadlifting and reported resolution in "approximately 2 injections" after massage, heat, and electrical stimulation had all failed. Dose is a discussed range (300-500mcg, 2-3 times per week), not his exact personal dose. Sourced from Huberman Lab Ep 170. Cycle 8 weeks on, 8-10 weeks off.
