what changed for me between week 95 and week 49

Medutest Cold Box ×5

Been lurking in c/bloodwork for about 14 months and finally have something worth posting.

Short version: week 16, 2.5mg, and test results is the bit I still cannot get a straight answer on. I have read the wiki, I have read the last 25 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 16.

Was that the vendor COA or your own test?

QYB / BPC / batch 13 / VendorInvestigate / 98.1% — that is the shape

Which VendorInvestigate service and what method did they use?

Mechanistically the bit that matters is below spec. It explains most of the early profile and a decent chunk of the outcome.

the Medutest and PeptideMeter results differ by 12 points, both inside inter-lab variance

multiple batches from KP show a spread, that is the data

testing the vendor claim versus testing your actual vial are two different posts

u/coring_the_stopper34 points·1 year ago

the vial you ordered versus the vial you received might be different batches

Disagree on that part. 93.7% and 99.3% on the same vial is normal.

reship and retest is the honest way to handle a low result

Small correction: the trial was 3 weeks, not 25. Does not change your point but people will quote it.

Yes, exactly this, and it is the bit that took me 91 weeks to accept.

The evidence standard in c/vendorvetting gets called too strict about once a month, and every time, the thread ends with the complainant agreeing.
