Corrections and Update Log

Affected: Not our error. Recorded because we published the query and owe readers the resolution.

What we said: On 26 July 2026 we published an open query about a figure on NexLife (opens nexlife.us in a new tab)'s own page stating that SURMOUNT-1 participants lost up to 24.3% of body weight, and logged it at status pending because we could not establish which analysis produced it.

What it now says: Resolved. No published SURMOUNT-1 analysis reports 24.3%. Lilly's own announcement states up to 22.5% for the efficacy estimand at 15 mg. The only 24.3 in the SURMOUNT-1 literature is a median time to weight plateau of 24.3 weeks. We have asked NexLife (opens nexlife.us in a new tab) to correct the figure.

Why it was wrong: We publish our open queries, so we publish their resolution, including when the answer is inconvenient for the provider we feature. A query left permanently open is a smear; a query resolved is a check.

Affected: Every page emitting a reviewedBy credit, and the medical reviewers page

What we said: We recorded Jonathan Michael Snipes MD (NPI 1821250077) and Kim Callender FNP-BC as this publication's named medical reviewers, and emitted a reviewedBy credit naming Dr Snipes in the structured data of 526 pages.

What it now says: Both individuals are named on RxPepsDirect's own published pages as its medical director and prescribers, and as the medical reviewers of its competing comparison of compounded tirzepatide telehealth services — a comparison in which RxPepsDirect ranks itself cheapest. RxPepsDirect sells the category this publication reviews. The reviewer credit has been suspended sitewide and the reviewedBy structured data removed pending resolution.

Why it was wrong: Our conflicts policy states that no clinician reviews a page about a company they work for, consult to or hold an interest in. We recorded two NPIs and never checked what those clinicians do elsewhere. That is the check the policy exists to require, and we did not run it.

Affected: All peptide pages referencing the FDA compounding advisory committee

What we said: We wrote that briefing documents posted 30 June 2026 recommended against adding BPC-157, TB-500 and five further peptides to the 503A list, and that the regulatory direction was toward closing the compounding route.

What it now says: FDA staff reviewers did recommend against all seven. On 23 July 2026 the advisory committee voted the other way — 8-6 with one abstention in favour of BPC-157, KPV and TB-500, and 7-5 with two abstentions for MOTS-c — overriding its own agency's scientists. The votes are non-binding and the FDA decides through formal rulemaking, which commonly takes 8 to 12 months.

Why it was wrong: We published the staff recommendation as though it predicted the committee outcome. It did not. The direction of travel reversed within two days of publication, and describing a live regulatory process by its most recent document is a mistake we should not repeat.

Affected: All pages describing the tirzepatide shortage timeline

What we said: We wrote that the tirzepatide shortage was declared resolved in October 2024, as a single settled event.

What it now says: FDA determined the shortage resolved on 2 October 2024. On 22 October 2024 that decision was remanded to the agency for reevaluation as part of litigation. On 5 March 2025 a district court denied the plaintiffs' preliminary injunction in Outsourcing Facilities Association v. FDA. Some sources date the resolution to December 2024 for that reason.

Why it was wrong: We compressed a contested twelve-month sequence into one date. The litigation is material context for anyone assessing how settled the current regulatory position is.

Affected: All pages showing a tirzepatide titration schedule

What we said: We published a fixed week-by-week escalation calendar: 2.5 mg for weeks 1–4, 5 mg for weeks 5–8, 7.5 mg for weeks 9–12, and so on through 15 mg by week 21.

What it now says: The Zepbound label directs 2.5 mg once weekly for 4 weeks, an increase to 5 mg, then increases in 2.5 mg increments no sooner than every 4 weeks based on tolerability and response, to a maximum of 15 mg. It names 5, 10 and 15 mg as the recommended maintenance dosages; 7.5 and 12.5 mg are titration steps.

Why it was wrong: We had taken the schedule from a secondary summary rather than the label. Presenting a minimum interval as a calendar implies escalation is automatic. On a page about dosing, that is the wrong impression to leave.

Affected: All pharmacy verification pages referencing 503B facilities

What we said: We wrote that 503B outsourcing facilities must comply with CGMP, in a context implying that registration demonstrated compliance.

What it now says: CGMP compliance is a legal requirement under section 503B. FDA states separately that registration means only that the agency received the required information — it does not mean the facility is making FDA-approved drugs, and it does not mean it is in compliance with CGMP.

Why it was wrong: Our wording let a legal requirement carry the weight of a verified fact. The useful question is whether a facility has been inspected and what the inspection found.

Affected: All pages comparing the $149 FDA-approved oral options against compounded programmes

What we said: We reported that the cheapest FDA-approved GLP-1 is now $149 a month and undercuts most of the compounded market, without stating the efficacy of the products being compared.

What it now says: The same pages now carry the efficacy ladder. Orforglipron reported approximately 11–12.4% mean reduction in ATTAIN-1 and oral semaglutide 13.6–16.6% in OASIS 4, against about 20.9% for tirzepatide 15 mg in SURMOUNT-1. Both $149 options are the least effective approved products.

Why it was wrong: The price statement was accurate and the comparison was incomplete. Comparing a roughly 12% drug with a roughly 21% drug on price alone is the error this publication exists to catch.
