Pulled your hamstring (sprinting / hockey / soccer). TB-500?

A-Tier Recovery Moderate anecdotal

Why people use TB-500 for hamstring injury

Pulled your hamstring (sprinting / hockey / soccer). TB-500? The honest answer: it is mixed - some real signal, a lot of anecdote. Athletes' favored peptide for muscle-tear recovery, particularly high-velocity injuries.

This page covers what's known, what's not, and what the editorial take is for normal humans considering TB-500 for hamstring injury.

What the evidence says

Evidence tier: Moderate anecdotal. Strong real-world anecdotal track record; mechanism extrapolates from related research.

  • Athletes' favored peptide for muscle-tear recovery, particularly high-velocity injuries.
  • Pairs well with eccentric rehab protocols.
  • No RCT data; mechanism extrapolates from animal soft-tissue work.

Protocol notes

2mg twice weekly for 4 weeks. Resume sport gradually with PT clearance.

Always with a sports-medicine doctor, telehealth provider, or specialist sign-off. Self-experimenting on injection schedules without clinical input is the most common way people waste money and get hurt.

What to skip

  • Vendors without a Certificate of Analysis (COA). Random gym-bro vendors with no third-party testing. The peptide market has a quality-control problem; the answer is COA per peptide, every time.
  • Pre-mixed blends from non-pharmacy sources. Compounding pharmacies that produce pre-mixed combinations with COAs are fine. Random vendor "stack vials" are not.
  • Massively over-dosed protocols. More is rarely better with peptides. Receptor saturation is real. Stick to evidence-based dosing.
