[Question] how do you actually verify mg/mL
how do you actually verify mg/mL. I would rather ask a basic question now than get this wrong quietly for two months. Adding more water does not change how much peptide…

comment on what changed for me between month 5 and month 8 in c/survodutide · 0 points · 1 year ago
Histological endpoints in this field are scored on biopsy: resolution of steatohepatitis without worsening of fibrosis, or improvement in fibrosis without worsening of steatohepatitis. Both are harder to achieve and to interpret than an imaging surrogate.
comment on the UK: network, and what it actually costs here in c/cryptopay · 48 points · 1 year ago
Confirmation took forty minutes on a busy evening and I had already written half an angry message. Deleted it.
comment on the crypto thing finally clicked for me and I want to write it down in c/cryptopay · 13 points · 1 year ago
A token symbol identifies an asset, not a network. The same symbol commonly exists on several chains with incompatible address formats, and sending across that boundary is generally unrecoverable.
comment on [Lab] split one vial across Janoshik and Medutest — 98.1% and 97.6% in c/coa · 27 points · 1 year ago
Correction: that is net peptide content, not purity. Different number, different meaning, and the document says so if you read the row label.
comment on [Discussion] TRIUMPH is doing more work than we give it credit for in c/trialwatch · 1 points · 1 year ago
Careful with that mean. The distribution around it was wide enough that it describes very few individual participants.
comment on reading MASH threads from 2024 and half of it aged badly in c/survodutide · 29 points · 1 year ago
read the histology endpoint definitions before quoting a response rate
comment on [Discussion] the insulin syringe advice in here is 2 years out of date in c/reconstitution · 5 points · 1 year ago
Wrote the date on the vial as well as the concentration after losing track of which one was opened first.
comment on reading confirmations threads from 2024 and half of it aged badly in c/cryptopay · 63 points · 2 years ago
Push back: an unconfirmed transaction is not a missing payment. Wait for confirmations before escalating.
comment on [Question] how do you actually verify mg/mL in c/reconstitution · 17 points · 2 years ago
What is written on the vial right now?
comment on [Question] how do you actually verify mg/mL in c/reconstitution · 34 points · 2 years ago
Correcting myself above: I wrote the concentration the wrong way up. Mass over volume, not volume over mass.

Are you accounting for the powder volume, or is that where the confusion is?
comment on someone explain survodutide to me like I have not read a paper in years in c/survodutide · 14 points · 2 years ago
Biopsy-confirmed population or imaging-selected?
comment on [Discussion] we are measuring network at the wrong time and calling it noise in c/cryptopay · 158 points · 2 years ago
Confirmations are the count of blocks built on top of the one containing your transaction. Until there are some, the transaction is not settled in any meaningful sense.
comment on SELECT: what the trials say vs what this community says in c/trialwatch · 289 points · 2 years ago
Absolute or relative risk reduction?
comment on why does nobody talk about biopsy in c/survodutide · -27 points · 2 years ago
Which endpoint — histological response, fibrosis improvement, or fat fraction?
comment on three years of bacteriostatic water threads, summarised so you do not have to read them in c/reconstitution · 55 points · 2 years ago
swirl, never shake
comment on [Discussion] related substances are doing more work than we give it credit for in c/coa · 202 points · 2 years ago
area% is not mass%, and the difference is the whole game
comment on [Vendor] SSA vs TFC on the same compound, same month — both cleared 97.5% in c/coa · 40 points · 2 years ago
net peptide content and purity are two different numbers on the same vial
comment on [Discussion] the units advice in here is 2 years out of date in c/reconstitution · 2 points · 2 years ago
Small fix — a U-100 syringe is 100 units per mL. If yours is marked differently it is not U-100 and the whole calculation changes.
comment on how much of what we believe about COA actually comes from area percent threads in c/coa · 29 points · 2 years ago
That is the catalogue certificate rather than the batch-specific one. Same layout, completely different status.
comment on [Lab] 8th independent test on JEEP — 97.2% on a claimed 97.0%, and the trend is the interesting part in c/survodutide · 8 points · 2 years ago
MASH endpoints are histological, which is a much harder bar
Disagreeing with this bit: that number comes from a different programme with a different population.
comment on [Discussion] the mg/mL advice in here is 3 years out of date in c/reconstitution · 15 points · 2 years ago
swirl, never shake
comment on [Meta] proposal — a flair for batch posts in c/coa · 69 points · 2 years ago
HPLC-UV and LC-MS answer different questions
comment on unpopular opinion: most of what gets said here about hazard ratio is guesswork in c/trialwatch · 35 points · 2 years ago
Agreed. Half the arguments on this site are two people quoting different trials at each other without noticing.

the memo field matters on the chains that use one
comment on how much of what we believe about endpoint actually comes from SURMOUNT threads in c/trialwatch · 26 points · 2 years ago
Intention-to-treat analyses everybody randomised regardless of what they did afterwards. Completer analyses only those who finished. The second is systematically more flattering and both are legitimate if labelled.

comment on [Question] how do you actually verify insulin syringe in c/reconstitution · 56 points · 2 years ago
Adding more water does not change how much peptide is in the vial. It changes the concentration, which changes the volume you draw for the same amount. That is the entire relationship.
