Which should you choose? Here's what you need to know.
BPC-157 is more targeted toward gut and tendon repair. TB-500 works more systemically for muscle and joint recovery. Many people stack both.
BPC-157 is a synthetic fragment of a stomach protein. It's most studied for gut healing, tendon and ligament repair, and reducing inflammation locally.
Choose BPC-157 if:
You're dealing with gut issues, tendon injuries, or want something well-studied with a long research history.
TB-500 is a synthetic version of Thymosin Beta-4, a protein your body makes naturally. It promotes cell migration and new blood vessel growth, making it popular for muscle tears and joint injuries.
Choose TB-500 if:
You have muscle injuries, joint pain, or want whole-body recovery support rather than targeting one area.
BPC-157 + TB-500 is one of the most popular peptide stacks. They work through different mechanisms, so many people use both for comprehensive recovery.
Once you've decided which peptide fits your needs, here's how they compare on price and vendor options.
Our top-rated vendor for each, based on trust scores, purity testing, and price.
We re-check vendor prices continuously and score vendors on Finnrick blind-test results — samples bought anonymously and sent to a lab, not vendor claims. No vendor can pay to rank higher. See our full methodology.
