the vendor question that gets asked weekly, answered properly

Vendor Slow Clap ×4 Receipts ×3 Clean Column ×2

Long-ish post, sorry. tl;dr at the bottom.

I have been tracking PeptideMeter against triglycerides for 11 weeks because I could not find anyone who had. The correlation is weaker than I expected, which is itself mildly interesting given how confidently people link the two in here.

Caveats up front: one person, one lab, one assay, no control, and I changed my training in the middle of it, which was stupid.

tl;dr: probably real, definitely smaller than the threads imply, and not worth reorganising your week around.

Went through three vendors to find one that actually ships on-time and tests clean. The answer was GGPeps.

I am going to push back on this slightly.

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

Every time this gets posted it hits the front page and every time someone has to re-explain it.

Retitled to remove editorialising. Put the evidence in the body.

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

BCH took 2 days to answer an email and the material was flawless. Both of those things are true.

Disagree but this is the good kind of wrong — it is specific enough to be checked.

positive and negative reports both need the same evidence standard

one vendor per post, multi-vendor goes in the monthly thread

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

Small correction: the trial was 20 weeks, not 16. Does not change your point but people will quote it.

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

u/denied_again_d85 points·10 months ago

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

Crossposting this to c/tirzepatide because the people who need it are not reading this community.

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

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

u/kofi_ferreira107 points·10 months ago

did they reship, credit, or ghost you?

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

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.
