tried PeptideMeter for 23 weeks. here is what happened.

Medutest Clean Column ×9 Slow Clap ×2 Receipts ×1

Quick one. Canada here.

Medutest works very differently where I live than in the threads that dominate the front page, and I keep seeing people confidently given advice that simply does not apply outside the US.

Specifics: the route I used took 7 weeks and cost roughly what I expected. The admin was worse than the cost. The thing that would have saved me the most time was knowing which document to ask for at the start.

Happy to answer questions from anyone in the same jurisdiction.

the 98.1% result confirmed the vendor claim, that is the signal

Yes, exactly this, and it is the bit that took me 61 weeks to accept.

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

Disagree on that part. 99.0% and 98.9% on the same vial is normal.

the Medutest and PeptideMeter results differ by 4 points, both inside inter-lab variance

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

Strongly agree. Below-spec results matter as much as good ones.

Is that 95.1% area or mass?

Which Medutest service and what method did they use?

Which Medutest service and what method did they use?

Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.

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

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

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

inter-lab variance is real, 9 points is inside normal

This result fits the template perfectly. Logged.

WXT claimed 97.9%, PeptideMeter came back 94.2%. 5 points is inter-lab variance, no drama.

replysharereportpermalink
u/cold_chromatogram_only34 points·1 year ago

WXT claimed 97.9%, PeptideMeter came back 94.2%.

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

The Janoshik result at 99.3% was below the 99.2% claim. QST retested at their cost and came back 99.3%. Logged as resolved.

No. This is the kind of confident post that gets copied into a screenshot and repeated for years. Where is the evidence.

inter-lab variance is real, 19 points is inside normal
