comment on [Discussion] can we stop arguing about reconstitution until somebody posts a number in c/reconstitution · 156 points · 1 year ago
Shook the first vial because nobody told me not to. It was fine, but I have swirled every one since.

Did the maths give you a whole number of units, or a fraction?

I would not round that figure.
Adding one thing — put the date on the label too. Concentration plus date and you can never mix two vials up.
comment on [Discussion] the chargeback advice in here is 3 years out of date in c/cryptopay · 15 points · 1 year ago
Some chains require a memo or destination tag to route funds to the right account.
Agreed — and the hash is the receipt. Nothing else is.
comment on three years of water content threads, summarised so you do not have to read them in c/coa · 209 points · 1 year ago
Net peptide content is the fraction of the powder that is actually peptide once counterion, water and residual solvent are accounted for.
rohan_steiner has the distinction right — one is a fraction of the detector signal, the other is a fraction of the mass.
comment on [Question] mg/mL — what am I missing here in c/reconstitution · 97 points · 1 year ago
That only works if the fill weight is exactly the label weight, and it usually is not exactly anything.
comment on glucagon is the most under-discussed thing on this board in c/survodutide · 174 points · 1 year ago
It is a dual agonist at the GLP-1 and glucagon receptors. The glucagon arm is associated with increased energy expenditure and with effects on hepatic fat, which is why the development programme is oriented towards liver disease.
comment on how much of what we believe about chargeback actually comes from crypto threads in c/cryptopay · 24 points · 1 year ago
network and address, checked twice, before anything else
comment on [Discussion] the excursion advice in here is 2 years out of date in c/coldchain · 126 points · 1 year ago
Right, and asking what the stability statement was written against is one line of email that reframes everything.
comment on someone explain dead space to me like I have not read a paper in years in c/reconstitution · 103 points · 2 years ago
Disagree with the "more water is safer" framing. It is not safer, it is just a different number to divide by.
comment on the gas fees question that gets asked weekly, answered properly in c/cryptopay · 12 points · 2 years ago
Correction: that address format is not the chain you named. Worth checking before anybody follows this.
comment on [Discussion] mg/mL is doing more work than we give it credit for in c/reconstitution · 2 points · 2 years ago
Show the arithmetic — where did the unit figure come from?
comment on why does nobody talk about biopsy in c/survodutide · 96 points · 2 years 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 how much of what we believe about COA actually comes from area percent threads in c/coa · 20 points · 2 years ago
Cosigning. The batch identifier is load-bearing, and a certificate that cannot be tied to the vial in your hand is not about your vial.
comment on [Discussion] the mg/mL advice in here is 3 years out of date in c/reconstitution · 47 points · 2 years ago
dead space in the needle hub is real and it is small
comment on [Lab] 16th independent test on WXT — 99.3% on a claimed 98.5%, and the trend is the interesting part in c/coa · 147 points · 2 years ago
LC-MS gives you identity; UV purity gives you a relative quantity. A document with the first and not the second, or the reverse, is answering half the question.
comment on bacteriostatic water — 16 things I got wrong before I got it right in c/reconstitution · 28 points · 2 years ago
5mg into 3mL is 1.67mg/mL, and 0.5mg of that is 30 units
comment on [Discussion] the area percent advice in here is 2 years out of date in c/coa · 18 points · 2 years ago
Right, and net peptide content is where the counterion and the water go. Both numbers can be honest and very different.
