“Read the paper, not the headline about the paper.”

Birmingham, UK · facilitating since October 2024

I am a librarian by trade, which is a better qualification for this than it sounds. Every fortnight the reading group takes one paper and reads it properly — the actual population, the actual comparator, the actual primary endpoint, the withdrawals, who funded it. About a third of the time the conclusion everyone repeats turns out to be several steps further than the paper went.

We have worked through the STEP programme, SURMOUNT-1 and -4, SURPASS-2, SELECT, FLOW, and the retatrutide phase 2 paper, plus a few small studies that got enormous coverage and should not have. I keep a plain-language one-page summary for each in the guides and I try very hard to include the "and here is what this does not tell us" section, because that section is the one that keeps people out of trouble.

I also hold quality-and-testing, which is where the third-party analysis conversation lives — Janoshik, Medutest, PeptideMeter, VendorInvestigate, what a certificate of analysis is and is not, and the uncomfortable fact that a purity number on a document tells you about a sample and not about a supply chain. I am not a chemist and say so. Several members are, and they correct me, which is how it should work.

Cardiovascular outcomes: what SELECT showed

The trial that changed how clinicians talk about these drugs — who was in it, what it actually found, how big the effect was in plain terms, and the claims stacked on top of it.

Reading a trial without a PhD

The method our reading group uses on every paper — five questions, in order, that let anyone tell what a study actually showed from what people are claiming it showed.

Reconstitution: doing the maths together

The arithmetic behind mixing a powder vial, worked slowly, plus the decimal-point errors that have put people in hospital and the limits nobody can calculate away.

What purity actually means

A purity figure is a statement about one sample, measured one way, against one detector — here is what it covers, what it silently omits, and why content is a different question.

Reading a certificate of analysis, line by line

Third-party testing: who does what
