am I the only one who found test results harder than the injections

Medutest Cold Box ×1 Clean Column ×2

Quick one. Canada here.

below spec 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 5 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.

I am going to push back on this slightly.

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

inter-lab variance is real, 4 points is inside normal

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

Not convinced. The evidence does not support that reading.

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

Yes, exactly this, and it is the bit that took me 38 weeks to accept.

Was that the vendor COA or your own test?

Is that 93.7% area or mass?

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

This is an urgent-care question wearing a forum question's clothes. Please contact a clinician rather than waiting for replies.

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

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

inter-lab variance is real, 17 points is inside normal

the 98.4% result confirmed the vendor claim, that is the signal

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

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

u/noor_vermeulen34 points·4 months ago

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

u/enzo_fonseca47 points·3 months ago

Mechanistically the bit that matters is below spec. It explains most of the early profile and a decent chunk of the outcome.

QST / BPC / batch 3 / VendorInvestigate / 93.7% — that is the shape
