does PeptideMeter actually matter or is it forum lore at this point

Discussion

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

The claim: vendor matters. The counter-claim: it is measurement error. Both sides have been asserting it confidently for about 11 months without either producing anything.

What would actually settle it is 27 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.

Rodent data is rodent data. Dose scaling is not linear and the models tell you what to investigate, not what to expect.

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

Small correction: the trial was 9 weeks, not 37. Does not change your point but people will quote it.

Reship, credit, or they ghosted you? That matters.

Cosigning the evidence standard. Receipts make the community.

This order history matches mine almost exactly. Same vendor, same timeframe, same result.

Yes, exactly this, and it is the bit that took me 50 weeks to accept.

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.
