The compound with the thinner record
TB-500 is the other compound the nickname joins. Its paper trail is thinner than the record for BPC-157, and this page describes the thinness plainly, without turning a missing document into an accusation.

The certificates page shows two records as Pending. They are Epithalon and Glutathione. TB-500 is neither of them, so the negative we can publish is a narrow one: TB-500 is not among the two records marked Pending.
Four second-laboratory bacterial endotoxin reports are published, covering the BPC-157 batch and the Retatrutide, Tirzepatide and GHK-Cu batches. TB-500 is not among the four. That is the document asymmetry the nickname hides: the two compounds it joins do not carry the same paperwork.
We downloaded no file for TB-500, and we say so rather than imply otherwise. We opened two BPC-157 assets and nothing for TB-500, so any claim that we read a TB-500 document would be false. The catalog as a whole reports measured purity between 98.6 and 99.6 percent, and because that figure belongs to the catalog and not to any single compound, we never attach it to TB-500.
One word puts these two compounds together. The records keep them apart. That is not a verdict on either compound. It is a fact about how much has been published about each, which is why the fuller record, for comparison reads the way it does, and why the name that joins them anyway is worth reading closely.
Everything this page names is research-grade material, or a report of one, set down for readers who open certificates themselves. The supplier we link is not a medical provider, nothing it sells is an FDA-approved drug, and no sentence here tells any person what to take or whether to take anything.
