how much of what we believe about Medutest actually comes from batch threads

Lab Cold Box ×4 Sourced ×2

Asking properly rather than in a comment on somebody else’s thread: how much of what we believe about Medutest actually comes from batch threads.

Tested three lots over a year rather than three vials from one lot. Cost the same and told me something completely different.

Sent a vial in specifically to check a supplier’s claim after a good experience. It matched. Boring result, worth logging.

Have now spent more on testing than on some of the orders. No regrets — the log is the reason I can buy without agonising.

Screenshot none of this. Read the whole thread, including the parts where I am told I am wrong.

Chain of custody is why member-funded testing is worth more than a supplied certificate: the vial tested is the vial that arrived at a member’s door.

Merged with the other thread on the same batch so the results sit together.

a result with no batch number is about a vial nobody can identify

How many separate lots does your series cover?

The template is vendor, compound, batch, service, claim, result, and who paid. Every one of those fields exists because a result missing it has been argued about here before.

if you are going to test, test the thing you actually received

the log is cumulative, that is the whole value of it

Which service, and did you pay for it yourself?

u/honest_syringe52 points·4 months ago

Right, and a point or two between services is ordinary. It is agreement, and every month somebody posts it as a scandal.

inter-lab variance runs a point or two, plan your outrage accordingly

Push back: three tests on one lot is one lot. It tells you about that lot and almost nothing about the next one.

Date of analysis anchors the result to a manufacturing period. A two-year-old result is evidence about two years ago and should be read that way.

Is that the same lot as the one in the thread from last month?

Area percent and net peptide content are different measurements and most reports give one. Quote which, or the comparison downstream is meaningless.

Correcting myself: I quoted net peptide content against somebody else’s area percent. Not a comparison.

Kept every report as a PDF with the batch in the filename. Two years in, it is the most useful folder I own.
