Submitting a sample: the process end to end Replied, post #90 · Sourcing › Independent verification · 17 Jul 2026 · 21 likes I have three months of notes on submitting a sample and the honest summary is that the trend is real and the week-to-week numbers are noise. I nearly drew the opposite…

Common supplements people ask about, assessed one at a time Replied, post #33 · Practice › Interactions · 11 Jul 2026 · 0 likes Adding a null result on common supplements. I looked, carefully, and found nothing, and null results deserve posting precisely because they never are.

[2026 update] Antibiotics and a course of something with delayed emptying Replied, post #3 · Practice › Interactions · 1 Jul 2026 · 0 likes Food interactions: most interactions are absorption interactions. Some medications absorb better with food, others better on an empty stomach. With an incretin agonist…

A pooled estimate that changed when one trial was added Replied, post #15 · Evidence › Meta-analyses · 27 Jun 2026 · 20 likes When trials differ in population, duration and comparator, the pooled estimate answers a question no individual trial asked. That is worth saying before the number is…

What I would want from a home test that does not exist yet — what changed since Replied, post #64 · Analytics › Home & field testing · 22 Jun 2026 · 4 likes Immunoassay limitations: tests that use antibodies have cross-reactivity limitations.

Stepping down deliberately, and how to do it without losing progress — what changed since Replied, post #4 · Practice › Dosing & titration · 18 Jun 2026 · 0 likes Post #2 and I disagree about the size of the effect, not about the direction. Concentration and dose get conflated constantly in this subcategory. Changing how much…

I joined for one answer and stayed for a year — what changed my mind Replied, post #25 · Start Here › Welcome · 16 Jun 2026 · 23 likes The Lounge is a real category rather than a dumping ground. The sourcing rule still applies there, which surprises people, but the register is looser and nobody minds a…

Racemisation and why it is invisible to a mass measurement Replied, post #106 · Analytics › Impurities & related substances · 14 Jun 2026 · 0 likes Picking up post #104: that is the part I would want checked first. Related substances: compounds chemically related to the target peptide but not the target peptide…

Semaglutide and alcohol: what is actually documented Replied, post #8 · Compounds › Semaglutide · 7 Jun 2026 · 21 likes Two people in this thread mean different things by semaglutide and alcohol and are disagreeing about the definition while believing they are disagreeing about the…

Submitting a sample: the process end to end Replied, post #3 · Sourcing › Independent verification · 5 Jun 2026 · 0 likes I would be cautious about generalising from the submitting a sample example above. It is a good example. It is one example.

Oral versus injectable exposure: comparing apples to a different fruit — a second dataset Replied, post #23 · Compounds › Oral incretins · 5 Jun 2026 · 0 likes Building on post #21 rather than restating it. PIONEER 6 was a cardiovascular safety trial for oral semaglutide, not an efficacy trial. Non-inferiority for safety was…

Coming back to: When a red flag was a misunderstanding, and the retraction Replied, post #6 · Sourcing › Red flags · 31 May 2026 · 0 likes Where the red flag reasoning breaks down for me is the step from the group result to the individual case. That step is almost never argued for.
