# Contact TB-500 Source: Editorial Correspondence Only

> Contact TB-500 Source about the thymosin beta-4 and Ac-LKKTETQ research digest. Editorial correspondence only — not a clinic, not a pharmacy, and not a place to obtain any compound.

For corrections, citations and editorial questions about the research record.

## What this form is for

Use this form for editorial correspondence about TB-500 Source: corrections, citation questions, requests to clarify how a finding was tagged (fragment versus full-length thymosin beta-4), or notes on a study we should add to the ledger. We read everything that concerns the accuracy of the record.

We are an independent editorial project. We do not provide medical or legal advice, we do not respond to requests for dosing or administration guidance, and we cannot help anyone obtain TB-500 or any other compound. There is no clinic, pharmacy, or vendor behind this site, and nothing here is dispensed or sold.

## What we cannot answer

We cannot recommend a dose, a protocol, a route, or a supplier, and we will not advise on obtaining a substance outside the lawful framework. Questions about whether TB-500 is appropriate for an individual are clinical questions for a licensed prescriber, not editorial ones for us.

For the regulatory standing — FDA non-approval, the 503A Category 2 flag, and the WADA-prohibited status — the legal-status page states the present-tense facts from primary sources. If you believe a regulatory fact on this site is out of date, send the FDA or WADA citation and we will reconcile it.

TB-500 Source reconciles the Ac-LKKTETQ record line by line — each figure matched to its study, the seven-residue fragment held on a separate line from the full-length thymosin beta-4 its data borrow from, and the human-evidence line left openly unbalanced; a register of the facts, not a clinic, a pharmacy, or a prescription.
