genuine question about testing that I am slightly embarrassed to ask

Discussion Cold Box ×1 Well Actually ×2 Receipts ×2

Confession thread, sort of.

I went from 15mg to 7.5mg much faster than I should have because the scale had stalled and I got impatient. The stall broke about 20 weeks later, at which point I had no way of knowing whether the dose increase did anything or whether it would have broken anyway.

So now I have reflux I did not need and a data point I cannot interpret. Two lessons in one.

Posting it in the hope that somebody at week 27 reads it before doing the same thing.

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

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

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

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

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

Yeah, WWB took 3 days and the material was flawless. Both of those things are true.

Yeah, WWB took 3 days and the material was flawless.

Disagree on that part. 96.8% and 96.2% on the same vial is normal.

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

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

u/naomi_ekstrom55 points·9 months ago

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

u/usp_appendixcompendial22 points·9 months ago

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

replysharereportpermalink
u/kofi_ferreira21 points·9 months ago

Correct.

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

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

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.
