Publication patterns in the BPC-157 literature, examined Replied, post #46 · Compounds › Repair & healing peptides · 27 Jul 2026 · 10 likes Post #42 describes the usual case. This is about the unusual one. TB-500 is usually the 7-residue actin-binding fragment of thymosin beta-4, not the full 43-residue…
Stepping down deliberately, and how to do it without losing progress — what changed since Replied, post #96 · Practice › Dosing & titration · 25 Jul 2026 · 0 likes Concentration and dose get conflated constantly in this subcategory. Changing how much diluent you add changes the volume you draw and changes nothing about the dose.
eGFR fluctuation and the creatinine denominator problem — the long version Replied, post #9 · Clinical › Bloodwork · 17 Jul 2026 · 12 likes The thing about egfr fluctuation that took me longest to accept is that a plausible mechanism is not evidence of an effect. It is a reason to look, not a result.
Revisiting: Why the absence of controlled human data on BPC-157 matters more than people… Replied, post #36 · Compounds › Repair & healing peptides · 17 Jul 2026 · 4 likes For anyone arriving from search engines: this subcategory discusses published preclinical work and the absence of published clinical work.

What consumer-accessible tests can and cannot determine — a second dataset Replied, post #62 · Analytics › Home & field testing · 7 Jul 2026 · 3 likes Adding the boring version of consumer-accessible tests, because the interesting version keeps getting posted and the boring one is usually right. Check the ordinary…
A structured critique template this community uses — a second dataset Replied, post #29 · Evidence › Study critique · 5 Jul 2026 · 0 likes Narrowing post #28, because the general version has more than one answer. Per-protocol and intention-to-treat analyses answer different questions and neither is the…
Alcohol: what is documented and what is folklore Replied, post #83 · Practice › Interactions · 29 Jun 2026 · 25 likes Post #80 answers the question as asked. The question underneath it is different. Where a published interaction study exists it usually reports an area-under-curve…
Mass error in ppm: the arithmetic and the caveat — a second dataset Replied, post #12 · Analytics › Mass spectrometry · 23 Jun 2026 · 20 likes Purity and identity are different questions: LC-MS establishes that the species at a retention time has the expected mass. It does not establish how much of the sample…
Request: tag synonyms surfaced in search Replied, post #5 · Meta › Feature requests · 23 Jun 2026 · 2 likes Bookmarking this. I will come back when I have something worth adding.
