# Contact TB-500 Legal — Editorial correspondence channels > Editorial correspondence for TB-500 Legal: corrections, source suggestions, regulatory updates, and citation queries. The site does not provide medical, legal, or commercial services. What we accept correspondence on, and what we deliberately do not. ## Editorial correspondence We accept editorial correspondence on the following topics: factual corrections to the published material; suggestions of additional peer-reviewed sources or registered clinical trials we should reference; updates to the regulatory record we may have missed (new FDA actions, revisions to the WADA Prohibited List, USADA or IFHA sanction notices); and citation queries — for example, requests for the full bibliographic record behind a numbered reference. Correspondence on any of these topics is welcome and will be reviewed. We do not provide medical advice, treatment recommendations, dosing guidance for human use, or any service that requires a licensed health-care professional. We do not provide legal counsel on the importation, possession, or use of TB-500 in any jurisdiction. We do not provide product reviews, vendor recommendations, supplier introductions, or commercial referrals. Inquiries on those topics will not be answered. The site is a one-way publication: we publish the editorial record, and we respond to corrections and additions to that record. We do not offer consultations of any kind. ## How to reach us A standard contact form is provided below for written correspondence. Inquiries should be brief and should identify the page and specific passage being addressed where applicable. We aim to respond to substantive editorial correspondence within ten business days; volume permitting, all messages are read. This form does not constitute a request for medical, legal, or commercial services. Submission of the form does not establish any advisory, professional, or commercial relationship with the publisher. The publisher reserves the right not to respond to messages outside the editorial scope described above. --- An independent editorial survey of the published regulatory and research record — not a clinic, not a vendor, not legal counsel.
