Retest date, expiry date, and the two conventions being confused
A document is only as good as the chain that connects it to the material, and most chains here are two or three links longer than the paperwork admits.
TheCompound Journal
Reporting on incretins, compounding & the peptide supply chain
Everything filed in September 2025, the month of Volume 2, Number 9. The issue itself — cover, editor’s letter and table of contents — is here.
A document is only as good as the chain that connects it to the material, and most chains here are two or three links longer than the paperwork admits.
Reported from the sessions, and from the two hours afterwards.
The result is unremarkable. What the report omits is not.
A design note rather than a result: what the comparator was, and what that permits you to conclude.
The header identifies the batch, the table records the tests, and the footer says who is answerable. Two of the three are usually incomplete.
A tour of the source literatures, with an assessment of how far each legitimately reaches.
A proper account of an operation that existed, and of what closing it cost.
Reported from the analysis, not from a warning notice.
A design note rather than a result: what the comparator was, and what that permits you to conclude.
The route did not close because of a rule about peptides.
The published ladder exists because a protocol needed a single number. Practice has never followed it exactly, and the regulatory file never assumed it would.
Pancreatitis is rare, was adjudicated in the outcome programmes, and did not show the imbalance early case reports suggested.
A proper account of an operation that existed, and of what closing it cost.
Reported from the analysis, not from a warning notice.
Documentation practice is the only part of vendor quality a buyer can assess before purchase.
The document is four pages. Three of them are about dates.
The reference interval for alanine aminotransferase in most laboratories is derived from a population that included people with undiagnosed fatty liver.
A document is only as good as the chain that connects it to the material, and most chains here are two or three links longer than the paperwork admits.
Reported from the sessions, and from the two hours afterwards.
Reported from the analysis, not from a warning notice.
A design note rather than a result: what the comparator was, and what that permits you to conclude.
The evidence base is thin and the document says so, which is to its credit.
What was pre-specified, what was exploratory, and what was calculated afterwards by people who did not run the trial.
Where the curve flattens, what flattens with it, and what does not.
Three randomised withdrawal designs have tested what happens when treatment stops. Their results are consistent and they are consistently misreported.
Efficacy was never the question in this appraisal. Duration of treatment was.
A design note rather than a result: what the comparator was, and what that permits you to conclude.
The route did not close because of a rule about peptides.
Deamidation, oxidation, aggregation and hydrolysis account for nearly all of what happens to a peptide over time. Each has a characteristic residue, a characteristic…
Follow the resin, not the catalogue.
The supplier has not disputed the finding. It has not explained the gap either.
The evidence base is thin and the document says so, which is to its credit.
A proper account of an operation that existed, and of what closing it cost.
Lot-level verification with a public report is a real and achievable thing. It exists in this market, on a minority of listings.
Why the reason for stopping changes what happens afterwards.
A design note rather than a result: what the comparator was, and what that permits you to conclude.
The report states the gradient, the wavelength and the integration threshold, which is more than most.
A proper account of an operation that existed, and of what closing it cost.
The document is four pages. Three of them are about dates.
The Journal submitted split samples from single lots to three assay services, under names unconnected to this publication, and published each method alongside each result.
