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 Post #60 is the version of this I will quote in future. One addition. Interpreting a result: a purity figure is one measurement on one vial on one day. Agreement across…
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 Neither method is capable of detecting the month-to-month changes that people report detecting month to month.
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 Then the honest version is a comparison of the record shapes rather than the scores. How many results, over how long, from which services. That I would use.
What would change my mind about repair peptides: a specific answer Replied, post #7 · Compounds › Repair & healing peptides · 7 Jun 2026 · 14 likes The pentadecapeptide sequence is short and stable enough to survive conditions that would degrade a larger peptide, which is one of the few things about it that is well…
Official shortage notices and what they authorise Replied, post #59 · Access › Shortages · 20 May 2026 · 7 likes Worth separating two things that post #57 runs together. On official shortage notices I would separate what is worth knowing from what is worth acting on. The first…
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 Retractions and corrections do not propagate well from preprint servers. A citation that was fine when made can quietly become wrong. Not a strong opinion, just a…
