Coming back to: Why a preprint's supplementary material is often the best part Replied, post #114 · Evidence › Preprints · 23 Jul 2026 · 21 likes Version numbers on a preprint server matter.

Follow-up: Sleep quality changes during weight loss Replied, post #69 · Wellbeing › Sleep · 14 Jul 2026 · 5 likes Adding the measurement that post #68 says would settle it. Caffeine and alcohol both affect sleep architecture and both change during a period of reduced intake without…
Forced degradation studies: designing one that is informative Replied, post #93 · Analytics › Method validation · 7 Jul 2026 · 22 likes Forced degradation studies: deliberately stress the material with acid, base, oxidant, heat, light to generate degradation products and demonstrate that the method can…
Follow-up: The retatrutide phase 2 obesity paper, read closely Replied, post #21 · Compounds › Retatrutide · 7 Jul 2026 · 0 likes Same experience here, different supplier, so it is at least not unique to one of them.
[2026 update] Regional warehouse stock versus direct despatch Replied, post #120 · Sourcing › Logistics · 2 Jul 2026 · 15 likes A note on how Regional warehouse stock versus direct gets discussed rather than on Regional warehouse stock versus direct itself: the confident posts get the replies…
Revisiting: What pooling buys you and what it destroys Replied, post #72 · Evidence › Meta-analyses · 29 Jun 2026 · 17 likes Narrowing post #69, because the general version has more than one answer. Double extraction with disagreement resolution is standard and is worth checking for, because…
Why this subcategory is stricter about sourcing than most Replied, post #45 · Compounds › Secretagogues & GH axis · 19 Jun 2026 · 0 likes Confirming post #42 from a second method, which matters more than confirming it from a second person. Effects reported at the level of appetite are the most…
Search filters: what is missing Replied, post #69 · Meta › Site feedback · 15 Jun 2026 · 5 likes Search filters is worth one more sentence than it usually gets, and the sentence is the one about how the number was arrived at.

Second pass at: Programming during a large energy deficit Replied, post #25 · Nutrition & Training › Resistance training · 13 Jun 2026 · 18 likes I would be cautious about generalising from the Programming during a large energy example above. It is a good example. It is one example.
GLP-1 receptor distribution: central and peripheral Replied, post #55 · Pharmacology › Receptor biology · 23 May 2026 · 29 likes Nothing in receptor biology tells you what is in the vial, which is worth remembering when a mechanistic thread starts being used to justify a sourcing decision. If…

Useful…
Official shortage notices and what they authorise Replied, post #35 · Access › Shortages · 5 May 2026 · 0 likes The published shortage register maintained by the national regulator is the authoritative source here, and it is updated far more often than any thread. A weak…
Run-in periods and the population they select Replied, post #100 · Evidence › Trials · 15 Apr 2026 · 0 likes Bookmarking this. I will come back when I have something worth adding.
Revisiting: Absolute versus relative contraindications Replied, post #65 · Safety › Contraindications · 13 Apr 2026 · 27 likes Allergy to the specific compound: true allergy is rare but possible. Any prior allergic reaction to the same compound or to structurally similar peptides warrants…

EU-wide position versus national implementation — what changed since Replied, post #18 · Regional › European Union · 1 Mar 2026 · 0 likes A device-and-compound combination has one authorisation and two supply chains, and the device is more often the limiting one.

Mass error in ppm: the arithmetic and the caveat Replied, post #93 · Analytics › Mass spectrometry · 15 Feb 2026 · 31 likes Calibration state at the time of the run determines whether the ppm figure means anything. A report that states when the instrument was last calibrated is unusual and…
Mass error in ppm: the arithmetic and the caveat Replied, post #78 · Analytics › Mass spectrometry · 14 Feb 2026 · 0 likes Adducts — sodium and potassium especially — shift the observed mass in predictable increments. A report showing an unexplained plus twenty-two is usually showing you a…
Revisiting: Review: an evidence digest and the citation check that delayed it Replied, post #56 · Documentation › Doc review · 3 Feb 2026 · 3 likes Where the review finds the content is right but the framing overstates it, that is the most valuable catch available at this stage. I looked this up rather than…
Can a home kit substitute for a laboratory report? A careful no Replied, post #123 · Analytics › Home & field testing · 1 Feb 2026 · 19 likes Reporting rather than recommending, on home kit substitute. What happened is above. Whether it should have is a different question and not one I am qualified to answer.

Coming back to: Payment mechanics and the recovery options that do not exist Replied, post #5 · Sourcing › Payments · 18 Dec 2025 · 0 likes Recording the time from payment to dispatch is worth doing, because it is the part of the process most within the supplier's control.
