why do vendor accounts always have the same three typos

Question

Trying to settle this properly because the thread from last year went in circles.

The claim: PeptideMeter matters. The counter-claim: it is measurement error. Both sides have been asserting it confidently for about 9 months without either producing anything.

What would actually settle it is 35 people measuring the same thing the same way. I have started; my numbers are below. They lean one way but not strongly enough for me to declare victory.

If you have data, post the data. If you have an opinion, flair it as an opinion.

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

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

u/laila_almeida21 points·24 days ago

independent test or vendor COA, which is it

Correct. The batch number is load-bearing information, not optional.

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

did they reship, credit, or ghost you?

Slight fix: the number was 98.7, not 99.3. Decimal point, but a fairly consequential one.

Not to be pedantic but reship and order records are being used interchangeably and they are not interchangeable in real life.

Half-life is about 168 hours, so steady state lands around week 17–5. Practical consequence: what you feel in week 1 is not what that dose does.

Did you test the vial you received or are we going off the vendor COA?

u/naomi_ekstrom1 point·23 days ago

receipts or nothing, sorry but that is the rule

How many orders from QSC is that a sample of? One reship is noise, five is a pattern.

How many orders from ERP is that a sample of? One reship is noise, five is a pattern.

The evidence standard in c/vendorvetting gets called too strict about once a month, and every time, the thread ends with the complainant agreeing.

About c/vendorvetting

The community due-diligence desk. Vendor experiences, independent third-party test results, shipping and reship records, and the boring paperwork that separates a supplier from a story. Every substantive claim is expected to carry a receipt: an order id, a dated screenshot, or a test report from Janoshik, Medutest, PeptideMeter or VendorInvestigate.

  5. Independent community. Nobody here sells anything, and anyone who tries is banned.
  6. Not medical advice. Describe what you did; never prescribe to a stranger.
