Same batch number on two different vendors means one thing and it is not good.

comment on three years of oral GLP-1 threads, summarised so you do not have to read them in c/orforglipron · 87 points · 1 year ago
It is a non-peptide small-molecule agonist at the GLP-1 receptor. That is a substantial medicinal chemistry achievement: getting a small molecule to activate a receptor evolved for a peptide ligand.

Has anyone posted an independent result on that batch?
piotr_grimaldi is right that a pure something-else is still something else.

I would not round that figure. At 2.5mg/mL a rounding error of two units is a real fraction of the intended amount.

Flair set to Vendor. Also a reminder that we take no money from any supplier in the directory.

Left up. It names an operation, it carries a date and a lot, and it is written as a report rather than an accusation.

Tracking number redacted from the post above. It identifies both ends of a shipment.

Working has to be shown on arithmetic posts.
Right, and the arithmetic behind it: 30mg in 3mL is 10mg/mL, so 2.5mg is 25 units.

The dead space question sent me down a rabbit hole for a week. It is a fraction of a unit and it is the same every draw.

Why the directory has two tiers, since the question comes up whenever somebody new finds it.
Twenty suppliers have enough independent results, over enough separate lots, over enough time, that the log says something. Those get a page, a test table and a link to their own storefront so you can compare their claims with the record.
The rest — nearly two hundred names — get a row, a band and a report count. Not because they are bad, but because two results is an anecdote about a vial. Manufacturing a score out of that would make the whole directory worthless, and the contrast is the point.

Small fix — the figure you quoted is the claimed purity from the certificate, and the independent result was the higher of the two.

Agreed on buying small first. The cost of a test is small next to the cost of committing to a supplier you have not checked.
