Studies and FDA pages used here
How do you check the BPC-157 TB-500 references?
Each number and claim about a study leads to its source. Below, you can open a study or FDA page and read the words for yourself.
How can you use this source list?
How can you trace a claim back to its source? The numbered list below gives you a study link or an FDA page for every claim.
The older studies near the top are where the rat results come from: tendons and ligaments that healed stronger, new blood vessels, faster-moving cells, and how chemists first made TB-500. Below them sit the reviews and rat studies from 2025-2026, which found the human evidence thin.
Near the end come the FDA pages about when a pharmacy may make a drug from a raw ingredient. I’d open those first if a clinic makes a claim about today’s legal rules.
Keep one warning in mind while reading the TB-500 studies. Most studies on repair examined the full Thymosin Beta-4 protein, not the far shorter form sold in a vial [4][9].
That difference may change what the finding means for your own care. The list below gives the full name and link for each study.
