comment on [Question] how do you actually verify bacteriostatic water in c/reconstitution · 31 points · 1 year ago
reconstituting at a round concentration makes every later dose easy
comment on the dead space question that gets asked weekly, answered properly in c/reconstitution · 10 points · 1 year ago
Spent 15 weeks confused about this until somebody drew the table for me. 15mg, 3mL, 5mg/mL, 0.25mg is 5 units. That is the whole thing.
comment on [Discussion] we are measuring plateau at the wrong time and calling it noise in c/semaglutide · 88 points · 1 year ago
Disagree. 2.4 is the top of the label, not the goal, and "everyone ends up there" is just survivorship in the posts you read.
comment on three years of units threads, summarised so you do not have to read them in c/reconstitution · 202 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 genuine question about units that I am slightly embarrassed to ask in c/reconstitution · 113 points · 1 year ago
Research-use-only material is not approved for human use, so treat everything in this thread as arithmetic about solutions rather than instructions for a person.
comment on [Results] 37 weeks, 6kg, and weekly dosing was the hard part in c/semaglutide · -37 points · 1 year ago
stalling at 2.4mg is information, not a verdict
comment on [Question] is 99.1% actually fine or am I being sold a rounding error in c/coa · -27 points · 1 year ago
Ask what the stability statement was written against — temperature, light, and whether it was the lyophilised powder or the reconstituted solution. Those are three different claims.
comment on the bacteriostatic water question that gets asked weekly, answered properly in c/reconstitution · -28 points · 1 year ago
5mg into 3mL is 1.67mg/mL, and 1.5mg of that is 90 units
comment on am I the only one who found plateau harder than the injections in c/semaglutide · 146 points · 1 year ago
What dose and how many weeks at it before this started?
comment on why does nobody talk about water content in c/coa · 26 points · 1 year ago
a total of 0.4% tells you less than four named impurities adding to 0.6%
comment on [Question] is 98.7% actually fine or am I being sold a rounding error in c/semaglutide · 382 points · 1 year ago
My stall was eleven weeks. Eleven. Then it moved again without me changing anything at all.
comment on bacteriostatic water is the most under-discussed thing on this board in c/reconstitution · 310 points · 1 year 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 [Lab] split one vial across Janoshik and Medutest — 98.1% and 97.6% in c/coa · 1 points · 1 year ago
That is the catalogue certificate rather than the batch-specific one. Same layout, completely different status.
comment on [Results] 57 weeks on 1.0mg, full numbers, ask me anything boring in c/semaglutide · 253 points · 1 year ago
do not chase somebody else’s titration schedule, they are not you
comment on purity is the most under-discussed thing on this board in c/coa · 173 points · 2 years ago
Agreed on asking for the storage condition. It is one line and it changes how you read the entire stability claim.
comment on [Vendor] SSA vs TFC on the same compound, same month — both cleared 97.5% in c/coa · 372 points · 2 years ago
Are the related substances itemised or is it a single total?
comment on how much of what we believe about COA actually comes from area percent threads in c/coa · 84 points · 2 years 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 titration — my 23-week log, condensed into one table in c/semaglutide · 140 points · 2 years ago
STEP-1 averaged just under 15% at 68 weeks, so a 10% year is not a failure
comment on titration — my 23-week log, condensed into one table in c/semaglutide · 53 points · 2 years ago
protein first, then everything else gets easier
comment on unpopular opinion: most of what gets said here about reconstitution is guesswork in c/reconstitution · 0 points · 2 years ago
Bacteriostatic water contains benzyl alcohol as a preservative, which is what makes repeated entry into the same vial reasonable.
viktor_kirchner has the units point exactly right. They are a volume on the barrel and nothing else.
comment on reading area percent threads from 2024 and half of it aged badly in c/coa · 83 points · 2 years ago
Yes. The structure of the document matters at least as much as the number printed on it.
comment on dead space — 16 things I got wrong before I got it right in c/reconstitution · 31 points · 2 years ago
label the vial with the date as well as the concentration
comment on [Question] how do you actually verify insulin syringe in c/reconstitution · 4 points · 2 years ago
Reconstituted at 3mL when I meant to use a different volume. Caught it because the units looked wrong on the barrel. Now I write 10mg/mL on the glass before I put the cap back.
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 · 41 points · 2 years ago
Sent one vial to VendorInvestigate and PeptideMeter. 99.6% and a claimed 99.0%. Cost me more than the vial and I would do it again.
