comment on 13 months in and basics are still the thing I get wrong in c/newbiequestions · 317 points · 1 year ago
A certificate of analysis is a document describing one batch: what was tested, by what method, and what the result was. Its value depends entirely on whether it names the batch and the method.
comment on someone explain mg/mL to me like I have not read a paper in years in c/reconstitution · 42 points · 1 year ago
Not quite. Bacteriostatic and sterile water are not interchangeable for a multi-draw vial, and the difference is the preservative.

Agreed — units are volume. Once that lands, the rest of the arithmetic is one division.
comment on do units actually matter or is it forum lore at this point in c/reconstitution · 559 points · 1 year ago
more water is not more drug, it is the same drug in a bigger volume
comment on [Results] 38 weeks, 6kg, and satiety was the hard part in c/cagrilintide · 30 points · 1 year ago
Kept a log purely because so few people are logging this one. It is one person and it is not data.
comment on [Question] is 95.1% actually fine or am I being sold a rounding error in c/scamalerts · 75 points · 1 year ago
pressure to decide today is the oldest signal there is
comment on the satiety question that gets asked weekly, answered properly in c/cagrilintide · -28 points · 1 year ago
read the combination arms separately from the monotherapy arms

Disagree with naming anyone on that basis. One person’s bad month is not a pattern and the sidebar exists for this exact reason.
comment on [Discussion] can we stop arguing about bacteriostatic water until somebody posts a number in c/reconstitution · 718 points · 1 year ago
aim the stream at the glass wall, not at the cake
comment on [Results] 16 weeks, 5kg, and basics were the hard part in c/newbiequestions · 207 points · 1 year ago
Removed the specific dose recommendation.
Adding the one habit worth starting today: write the concentration on the vial.
comment on is it normal to get constipation at week 11 in c/newbiequestions · 5 points · 1 year ago
Titration is a tolerance ladder.
Adding the one habit worth starting today: write the concentration on the vial.
comment on three years of insulin syringe threads, summarised so you do not have to read them in c/reconstitution · 290 points · 1 year ago
Aim the stream down the wall of the vial rather than into the cake. Reconstitution is a solubility problem, not a mixing problem, and mechanical shear does nothing helpful.
comment on [Discussion] the fraud advice in here is 2 years out of date in c/scamalerts · 4 points · 1 year ago
Same. A batch-specific document requested before payment costs nothing and filters an enormous amount.
comment on [Lab] WXT tirz — PeptideMeter came back 97.1% against a claimed 97.0% in c/scamalerts · 69 points · 2 years ago
the review page nobody can find on any other site is a warning
comment on help me understand first time, I have read the wiki twice in c/newbiequestions · 15 points · 2 years ago
pens and vials are the same molecule with different logistics
comment on help me understand first time, I have read the wiki twice in c/newbiequestions · 43 points · 2 years ago
Not quite. Bacteriostatic and sterile water are different products and only one is intended for repeated entry.

write the concentration on the vial, you will thank yourself
comment on [Meta] proposal — a flair for units posts in c/reconstitution · 242 points · 2 years ago
That is sterile water, not bacteriostatic. Same appearance, different product, and it matters for a multi-draw vial.
comment on small win: what is stopped being a problem at week 72 in c/newbiequestions · 11 points · 2 years ago
nobody here can tell you what dose to be on
comment on [Discussion] the mg/mL advice in here is 3 years out of date in c/reconstitution · 8 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.
comment on the basics question that gets asked weekly, answered properly in c/newbiequestions · 131 points · 2 years ago
the first month is a tolerance check, not a results phase
comment on why does nobody talk about units in c/reconstitution · 42 points · 2 years ago
do the arithmetic before you reconstitute, not while holding a syringe
