Why purity is the cheapest number to flatter
Peptide content, identity, aggregate burden, moisture and endotoxin are all more informative for some purposes. All of them cost more.
Attribution is the hard part
Rapid weight loss by any means raises gallstone risk. Separating that from a direct drug effect requires a comparator, and the trials have one.
The 14-day notice: how a compounding wind-down works in Ireland
The document is four pages. Three of them are about dates.
Inspectors cite Calder Vale Peptides of Skipton over sterility assurance
The observation that closes a facility is rarely the dramatic one.
Spain caps liraglutide prescribing to 24 specialist centres
Efficacy was never the question in this appraisal. Duration of treatment was.
Freezing a reconstituted vial: the ice-water interface problem
Bacteriostatic water contains benzyl alcohol at 0.9 per cent, which inhibits microbial growth in a preserved multiple-dose presentation. It does not sterilise a contaminated…
Denmark pharmacy body issues counselling standards for liraglutide initiation
The evidence base is thin and the document says so, which is to its credit.
The quiet end of the relabeller trading as Vantris Bio
A proper account of an operation that existed, and of what closing it cost.
The Netherlands declines to reimburse exenatide outside a specialist service
Efficacy was never the question in this appraisal. Duration of treatment was.
Changsha export categories for peptide intermediates were quietly renamed
Follow the resin, not the catalogue.
Storage after reconstitution, and the evidence behind the numbers
The air shot before a pen injection removes air from the cartridge and confirms flow. Skipping it can mean a materially reduced dose, and it is skipped constantly.
The dose that got you here and the dose that keeps you here
A survey of the maintenance evidence, which is shorter than the survey of the withdrawal evidence.
Inspectors cite the online reseller trading as Adamant Research Supply over sterility assurance
The observation that closes a facility is rarely the dramatic one.
The 22-day notice: how a compounding wind-down works in New Zealand
The document is four pages. Three of them are about dates.
TRIUMPH-3 misses on a secondary endpoint the coverage has not mentioned
A design note rather than a result: what the comparator was, and what that permits you to conclude.
Independent analysis puts a KP semaglutide lot at 95.6%, against 94.1% on the certificate
The Journal submitted the sample and paid for the analysis. The vendor was told in advance.
Tandem mass spectrometry, and the difference between weighing and reading
The Journal’s standing position: a mass that matches is necessary evidence of identity and nowhere near sufficient.
The badge is about a sample. The listing is about a product.
The Journal does not treat a badge as evidence and states so wherever it reports one.
A supplier suspends shipping to New Zealand after 12 consecutive customs detentions
The route did not close because of a rule about peptides.
What changed at QST in October, and what the company says prompted it
Documentation practice is the only part of vendor quality a buyer can assess before purchase.
PeptideMeter result on a Wuhan orforglipron lot lands 2.1 points above the supplier’s stated figure
The result is unremarkable. What the report states alongside it is not.
How a claim degrades between the bench and the listing
The Journal does not treat a badge as evidence and states so wherever it reports one.
Eating enough protein on a suppressed appetite is an arithmetic problem before it is a nutritional one
The resistance-training and energy-deficit literature supports a higher protein intake. None of it was conducted in people taking an incretin.
Homopeptide names the synthesis and fill sites behind its catalogue
Documentation practice is the only part of vendor quality a buyer can assess before purchase.
Hangzhou export categories for peptide intermediates were quietly renamed
Follow the resin, not the catalogue.
Independent analysis puts a GGPeps tirzepatide lot at 95.4%, against 92.1% on the certificate
A reminder that a purity figure is the output of a method, and that methods differ.
The consolidator trading as Meridian Freight Partners enters a consent decree and stops sterile preparation
The observation that closes a facility is rarely the dramatic one.
The lowest effective dose is a real concept with almost no data behind it
Dose reduction is not withdrawal, and the trials that tested withdrawal cannot be read as testing it.
Diminishing returns, quantified
Where the curve flattens, what flattens with it, and what does not.
