[Resolved] the QST batch dispute — vendor retested, numbers matched, my error

Resolved Receipts ×4

Posting this because I searched for it and got nothing useful.

Setup: 5mg, week 48, constipation present but not ruining anything. I changed exactly one variable — testing — and tracked it for 3 weeks.

Result: a difference, but a small one, and well inside what I would call noise if someone else posted it. So I am putting it here rather than presenting it as a finding. If two or three other people have done the same thing we might actually learn something.

Not medical advice, obviously. This is one person with a spreadsheet.

Titration speed is a side-effect dial far more than an efficacy dial.

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

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

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

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

Cosigning the evidence standard. Receipts make the community.

First order from HJ was great, second one had a different batch and tested lower. The vendor retested and credited me. Logged it here.

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

First order from MKM was great, second one had a different batch and tested lower. The vendor retested and credited me. Logged it here.

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

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

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.
