About This TB-500 Research Digest

What Prescribed TB-500 is

Prescribed TB-500 is an independent editorial project that publishes summaries of the peer-reviewed research literature on TB-500 — the synthetic Ac-LKKTETQ fragment of thymosin beta-4. We are not a clinic. We do not employ clinicians, and we do not provide medical advice. We do not manufacture, sell, or distribute any product. Our work is editorial commentary on publicly available science.

The "prescribed" in the name is editorial framing, not a service. It marks the position this digest takes toward the literature — reading the molecule the way a careful record-keeper would, including the regulatory and compounding context a "prescribed" medicine sits inside — not a claim that this site prescribes, dispenses, supplies, or facilitates access to anything. Nothing here is a prescription, an offer to supply, or a route to obtain TB-500.

The standard we hold

Every quantitative claim on this site cites a specific study, and each citation resolves to a PubMed record, a DOI, or an authoritative FDA page. We log findings with their species, dose and route, and we mark — every time — where a cited result was generated with full-length thymosin beta-4 (~4963 Da) rather than the ~889 Da TB-500 fragment, because conflating the two is the single most common error in writing about this molecule.

We describe what studies measured. We do not recommend doses for people, and we do not translate animal protocols into human regimens. Where the evidence is strong — the actin-binding structural work, for instance — we say so plainly. Where it is absent — no completed controlled human trial of the fragment exists — we say that too, and we do not let the parent protein's data fill the gap. The console aesthetic is deliberate: a record you can audit, not a landing page making a case.

What this site is not

This site is not a pharmacy, a telehealth provider, a supplement vendor, or a source of TB-500. It names no products and no suppliers. It does not advise on obtaining any substance, and its regulatory pages are general information about the landscape, not medical or legal advice. If you are weighing anything described here against a real decision, that decision belongs with a licensed professional who knows your situation — not with a research digest. The reason to be this explicit is the domain name itself. "Prescribed" can read as a promise of access, and it is not one. The word earns its place only as a lens — a commitment to read TB-500 inside the regulatory and compounding context a prescribed medicine would sit in, including the FDA 503A status and the WADA picture — and never as a service this site performs. We publish a record. What anyone does with it is theirs, ideally with a licensed professional in the room.
