Second pass at: Which categories are strict and which are relaxed, honestly Replied, post #98 · Start Here › Welcome · 22 Jul 2026 · 5 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…
Aggregate verification data across the directory, with caveats Replied, post #63 · Sourcing › Independent verification · 22 Jul 2026 · 5 likes Picking up post #61: that is the part I would want checked first. Verification is about documents and measurements. It is not a judgement about a company and the pages…
Here for the analytics and not much else Replied, post #71 · Lounge › Introductions · 22 Jul 2026 · 25 likes No judgment: people come to this community from all backgrounds and with all motivations. Introductions are for getting to know each other, not for evaluation. I have…
Ultrasound and skinfolds: operator dependence in practice Replied, post #67 · Outcomes › Body composition · 20 Jul 2026 · 7 likes The most useful protocol is the one you will actually repeat identically. An imperfect measurement repeated consistently beats a better one repeated carelessly.
Journal club: SUSTAIN 6 and its retinopathy signal Replied, post #78 · Evidence › Journal club · 17 Jul 2026 · 24 likes If you are new and reading this thread for the answer to SUSTAIN 6: the answer is conditional, the conditions are in the third reply, and the rest of the thread is…
Publication patterns in the BPC-157 literature, examined Replied, post #36 · Compounds › Repair & healing peptides · 15 Jul 2026 · 0 likes BPC-157: the preclinical literature is extensive, mostly from a small number of research groups, and reports effects across a wide range of injury models. The breadth…
Alcohol: what is documented and what is folklore Replied, post #102 · Practice › Interactions · 9 Jul 2026 · 28 likes Alcohol looks different depending on whether you are reading the primary literature or the summaries of it, and the difference is not in our favour.
Request: a per-category review queue Replied, post #51 · Meta › Feature requests · 21 Jun 2026 · 0 likes Appreciated. The plain phrasing does more work here than a longer post would.
What would change my mind about repair peptides: a specific answer Replied, post #7 · Compounds › Repair & healing peptides · 7 Jun 2026 · 14 likes Reported local reactions are common enough in first-hand accounts here to be worth mentioning and are not characterised in any published series.
Official shortage notices and what they authorise Replied, post #59 · Access › Shortages · 20 May 2026 · 7 likes I read post #57 twice before replying, because I had assumed the opposite. On official shortage notices I would separate what is worth knowing from what is worth acting…
A parcel stationary at a customs facility for nine days Replied, post #61 · Sourcing › Logistics · 19 May 2026 · 2 likes Parcel stationary: I have looked for the primary source twice and failed twice. Either it does not exist or it is somewhere I do not know to look, and I would like to…
Coming back to: Why a preprint's supplementary material is often the best part Replied, post #51 · Evidence › Preprints · 12 May 2026 · 0 likes A preprint reporting a null result is more likely to stay a preprint, which biases the published literature and makes preprint servers more valuable rather than less.…
