i say this constantly and get downvoted for it, and then someone says it better and gets upvoted. such is life.

upvotes measure agreement, not accuracy. it is on the disclaimer page and it should be on the front page.

six is more than most people have and still not enough to be a property. carry on being nervous, it is the correct amount of nervous.

this thread is basically a decent checklist by accident, someone should turn it into an actual wiki page

this is the most epistemically healthy comment on this site this month

one really nice DEXA pair is still one person's data, but this is the kind of specific mechanism-with-receipts post that actually teaches something regardless of sample size

one reship is a coincidence and two is still a coincidence. this is the same reasoning error as the JEEP thread.

my own interval has wandered 6-9 days across a year of real life logistics and I genuinely can't tell any difference, though that's exactly the kind of thing noise would also produce

the trials under-powered nearly every question in this community, which is why threads like this are the only evidence base available and why they should be read as exactly that.

one person's identity gap isn't universal, but the number of people agreeing in this thread suggests it's common enough to be worth naming properly rather than treating as an individual quirk

hoping someone eventually runs a proper comparison, feels overdue given how popular the topic is

a thread full of honest "might be noise" self-reports is more useful than five confident "it definitely helped" posts, oddly

one log is one data point, that said this is a genuinely useful one data point, the specificity is what makes it useful

eleven independent tests on this vendor in the log, which is more than almost anything else here. more sampling reveals more variance and people read that as "worse vendor", which it is not.

one person is not a study, one hundred people complaining about the same week on a forum is also not a study, but it is a pattern worth explaining somehow

should be a stickied graphic at this point

4/4 on time from the warehouse, 6/9 direct. averaging those into a single number is almost misleading and i say that about this vendor more than any other.

one gracious vendor response does not offset a bad batch record

take it, i will never write anything that useful again

the "can't fully separate the variables" honesty at the end is worth more than a clean story would have been, real self-experimentation is usually this messy

which is also an argument for the rating being an average of a lot of different scar tissue rather than any one person's judgement.

one good data point on an under-studied question is worth posting even though it's not proof of anything at scale, glad this exists

this thread and the noise-vs-plateau one should genuinely be linked together somewhere, they answer two halves of the same question

That is a pharmacy-level stock issue rather than a national supply issue. They feel identical and are not.

Are the related substances itemised or is it a single total?

Does the lot on the vial match the lot on the page?

the counterion is part of the mass you paid for

Net peptide content is the fraction of the powder that is actually peptide once counterion, water and residual solvent are accounted for. A 99% pure acetate salt can still be about 85% peptide by mass.

post the whole document, not the headline number

chromatogram or it did not happen

Does the lot on the vial match the lot on the page?

Are the related substances itemised or is it a single total?

Asked KP for the batch-specific certificate and had the full document — batch, date, method line naming the column — inside six hours. That is now my baseline for everybody.

The PDF creation date being later than the analysis date is usually a re-issue or a re-export. It is worth one question and it is not evidence of anything on its own.

Agreed — the itemised related substances table is the difference between a document and a receipt.

Correction: that is net peptide content, not purity. Different number, different meaning, and the document says so if you read the row label.

say which state only if it matters, but always say which country

net peptide content and purity are two different numbers on the same vial

The compounded arrangements changed while I was mid-thread and I was arguing from a superseded position.
