week 76 check-in — 12kg down, fatigue manageable, one thing confusing me

Lab Slow Clap ×4 Sourced ×3 Well Actually ×2

Right, the Janoshik question again, but with numbers this time.

I have 15 data points over 10 weeks. The pattern is consistent enough that I do not think it is chance, and boring enough that nobody is going to screenshot it, which is usually a good sign.

The thing I would flag for anyone new: the effect I am describing showed up at week 64, not week 18. People give up long before the interesting part.

Interested in whether this matches other people's logs or whether I am an outlier.

The practical rule people converge on is 28 days at fridge temperature after first puncture, and that comes from the preservative, not the peptide.

testing the vendor claim versus testing your actual vial are two different posts

the VendorInvestigate and PeptideMeter results differ by 19 points, both inside inter-lab variance

The Medutest result at 98.4% was below the 98.3% claim. BCH retested at their cost and came back 98.4%. Logged as resolved.

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

do not editorialise in the title, put the number in the title and the opinion in the body

The PeptideMeter result at 98.6% was below the 99.0% claim. BCH retested at their cost and came back 98.6%. Logged as resolved.

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

That is net peptide content, not purity. Different number, different meaning.

I am going to push back on this slightly.

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

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

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

inter-lab variance is real, 21 points is inside normal

the 93.7% result confirmed the vendor claim, that is the signal

the vial you ordered versus the vial you received might be different batches

The confident tone is doing a lot of work that the evidence is not.

Adding to this: Janoshik is doing more work than the comment implies.
