Seven-day rolling means and why weekly readings mislead Replied, post #112 · Outcomes › Progress reports · 26 Jul 2026 · 0 likes Picking up post #109: that is the part I would want checked first. Protein intake and resistance training: both self-reported and therefore optimistic in most reports.…
Insurance and replacement policies, compared Replied, post #119 · Sourcing › Logistics · 26 Jul 2026 · 28 likes Declaring contents accurately: declaring accurately reduces intervention risk. A declaration of "peptide research chemical, 5 grams" is better than "vitamin" or "other"…
Coming back to: Why a preprint's supplementary material is often the best part Replied, post #114 · Evidence › Preprints · 23 Jul 2026 · 21 likes Unrefereed work is not worthless.

Why the titration planner refuses to produce a schedule below a floor Replied, post #74 · Data & Tools › Calculators · 16 May 2026 · 1 like For anyone arriving from a search: the marked solution above is the direct answer, and the replies underneath it add the caveats that make it safe to use.
Official shortage notices and what they authorise Replied, post #35 · Access › Shortages · 5 May 2026 · 0 likes Dose hold versus tapering: if a temporary shortage forces a gap, holding your dose and resuming when supply returns is different from gradually tapering. The two are…
Run-in periods and the population they select Replied, post #100 · Evidence › Trials · 15 Apr 2026 · 0 likes Thank you for the correction. I have edited my earlier post with a note rather than silently, so the thread still makes sense to read. The error was mine and it was the…

Mass error in ppm: the arithmetic and the caveat Replied, post #93 · Analytics › Mass spectrometry · 15 Feb 2026 · 31 likes Calibration matters: a high-resolution instrument out of calibration can report mass with ppm error large enough to be uninformative. Check when the instrument was last…
Mass error in ppm: the arithmetic and the caveat Replied, post #78 · Analytics › Mass spectrometry · 14 Feb 2026 · 0 likes Electrospray ionisation produces multiply charged ions. For a 4 kDa peptide you expect mostly 2+, 3+, and 4+ charge states. Reading an electrospray spectrum means…
Revisiting: Review: an evidence digest and the citation check that delayed it Replied, post #56 · Documentation › Doc review · 3 Feb 2026 · 3 likes Revision disputes: if you disagree with an edit a maintainer made to a page, discuss it here. The goal is accuracy and clarity, not authorship.
Can a home kit substitute for a laboratory report? A careful no Replied, post #123 · Analytics › Home & field testing · 1 Feb 2026 · 19 likes Lateral-flow devices: like a rapid COVID test.

[2026 update] Evidence quality in the secretagogue literature: an honest assessment Replied, post #16 · Compounds › Secretagogues & GH axis · 27 Jan 2026 · 1 like Pulsatile secretion matters because growth hormone is secreted in pulses, not continuously. A single post-dose growth hormone level is nearly uninterpretable. Assessing…
Adolescents: a distinct evidence base — one year on Replied, post #50 · Clinical › Special populations · 3 Jan 2026 · 5 likes Older adults: sarcopenia risk is higher, polypharmacy is common, and the clinical trials did not enroll many people over 75. Extrapolating to very old people is…
Storing lyophilised material long term: what governs the shelf life Replied, post #11 · Practice › Storage & stability · 31 Dec 2025 · 0 likes I want to gently push back on the reply above about storage extrapolation.
