Discussion

Genuinely asking, not being difficult.

Everyone in c/glp1muscle repeats that Medutest is important. I believe it, but I have never seen anyone show why, and when I search I get 22 threads of people agreeing with each other.

Is there a paper? Is there a measurement? Or is this one of those things that is true because it has been repeated since 2023?

I am not trying to be the "source?" guy. I would just like a source.

Batch number? Date? Method? Give us the load-bearing fields.

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

u/lina_ndiaye5 points·20 days ago

Correct.

Yes, exactly this, and it is the bit that took me 19 weeks to accept.

Did you test the vial you received or are we going off the vendor COA?

WWB order #6, Spain, no drama, receipts inside

Small correction: the trial was 13 weeks, not 4. Does not change your point but people will quote it.

the reship rate on BCH is actually pretty consistent

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

positive and negative reports both need the same evidence standard

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

replysharereportpermalink
u/mikkel_kimani1 point·20 days ago

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

Reship experience: MKM asked for photos, processed it in 8 days, sent a replacement no questions. That is the template.

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

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.
