[Meta] the purity rule is doing its job and people should stop complaining

Below Spec Clean Column ×1 Slow Clap ×3 The Quiet One ×2

Genuinely asking, not being difficult.

Everyone in c/semaglutide repeats that below spec is important. I believe it, but I have never seen anyone show why, and when I search I get 2 threads of people agreeing with each other.

Is there a paper? Is there a measurement? Or is this one of those things that is true because it has been repeated since 2023?

I am not trying to be the "source?" guy. I would just like a source.

Was that the vendor COA or your own test?

Yeah, the Janoshik number matching the claim is the actual signal.

multiple batches from JEEP show a spread, that is the data

Respectfully this is a sample of one presented as a finding.

Removed a chain here. The rule is one line long and it is not negotiable.

Is that 98.9% area or mass?

Yes, exactly this, and it is the bit that took me 83 weeks to accept.

You have restated the marketing copy. What is the actual substance here.

Titration speed is a side-effect dial far more than an efficacy dial.

Tested 18 batches from KP over 78 weeks. Spread was 98.9% to 98.7, mostly 98.9. Consistent vendor.

My PeptideMeter result matched the vendor COA exactly, which is rare. QST deserves that note in the directory.

Crossposting this to c/sideeffects because the people who need it are not reading this community.

reship and retest is the honest way to handle a low result

u/fatima_wojcik3 points·10 months ago

the Medutest and PeptideMeter results differ by 9 points, both inside inter-lab variance
