[Meta] proposal — a flair for vendor posts

PSA Clean Column ×7 Long Haul ×3 Receipts ×2

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 17 months without either producing anything.

What would actually settle it is 37 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.

Half-life is about 168 hours, so steady state lands around week 14–5. Practical consequence: what you feel in week 1 is not what that dose does.

Is that a PeptideMeter result or are you quoting the vendor COA?

u/hamza_serrano1.6k points·2 years ago

Disagree. What you are describing is consistent with reship, not with what you concluded.

Water content matters more than people think. If a vial is carrying residual moisture, your "10mg" is not 10mg of peptide.

Water content matters more than people think.

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

Water content matters more than people think.

Disagree on that part. 97.4% and 98.3% on the same vial is normal.

I am going to push back on this slightly.

Edit to your parent would help — the concentration you quoted assumes one scenario and you have written another above it.

Order date, product, and result, in that order please?

I love that this community will spend 40 comments on a detail. That pedantry is why the numbers here matter.

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

Yes, exactly this, and it is the bit that took me 11 weeks to accept.

the VendorInvestigate result being close to the claim is the signal, not the absolute number

u/soren_zamora0 points·2 years ago

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

Tracking number removed. It identifies both ends of a shipment.

Yeah, GL Biochem took 10 days and the material was flawless. Both of those things are true.

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.
