TB-500 Legal

A customs-form reading of the TB-500 regulatory record — every clearance stamp, every refused entry.

PAGE 06 · PUBLISHER

An editorial project, not a clinic.

Who publishes this site, what it does, and what it deliberately does not do.

What this site is

TB-500 Legal reads the published record on Thymosin Beta-4 and its seven-amino-acid fragment Ac-LKKTETQ-OH the way a border officer reads a passport: document by document, jurisdiction by jurisdiction, checking each stamp against the authority that issued it. It is a reading desk, not a dispensary. Nothing here is sold, supplied, sourced, or shipped; no appointment is booked and no prescription is written; the desk keeps no clinicians and offers no medical or legal opinion on your circumstances. What it offers is a survey of what the FDA bulks list, the WADA Prohibited List, USADA and the horseracing authorities, and the peer-reviewed literature actually say — each factual claim carried back to the document that supports it.

Editorial standards

Every number on this site travels with its papers. A quantitative claim appears only when a specific peer-reviewed study, a registered trial, or a document of record stands behind it, and where the record is unsettled — for instance where vendor copy treats the synthetic fragment as interchangeable with full-length Tβ4 though the structural biology separates them — the site leaves the question open rather than settling it by assertion. Findings that failed to replicate are logged next to the ones that held. The desk promotes no seller, links to no research-chemical source, and points outward only to PubMed, PubMed Central, the NIH, ClinicalTrials.gov, journal pages, and the agencies themselves.

What we deliberately do not do

No person — invented or real — is named as author, physician, or reviewer here; the desk carries no byline because it reports on the record rather than practicing from it. It writes no dose for human use, hands out no treatment plan, and arranges no consultation, referral, or purchase. It does not rule on whether any particular shipment, possession, or use is lawful in a given place — that is a question for a licensed attorney who knows your facts. Regulatory standing shifts over time; every status noted here is dated to its page, and the issuing agency remains the authority of last resort.
