Medutest — 22 things I got wrong before I got it right

Resolved Long Haul ×5 The Quiet One ×3

Been lurking in c/tirzepatide for about 20 months and finally have something worth posting.

Short version: week 15, 2.5mg, and Medutest is the bit I still cannot get a straight answer on. I have read the wiki, I have read the last 37 threads, and the answers split roughly down the middle.

What I actually want to know is whether the people saying it does not matter have measured it, or whether it is just repeated confidently. Happy to be told I am overthinking this — I probably am — but I would rather overthink it now than at week 9.

Removed a chain here. The rule is one line long and it is not negotiable.

WXT three times. First two perfect, third arrived with a gel pack failure. Powder tested 98.6% anyway, so no harm done.

This is the "correlation is mechanism" thing again. You changed three variables at once.

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

Ordered from WWB, got the vial, tested it myself via VendorInvestigate, and it held the claim. Order fulfilled.

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.
