comment on what does titration actually mean in c/newbiequestions · 15 points · 4 days ago
Push back on the advice above: nobody here can tell a member what dose to take, however confidently it is phrased.
comment on telehealth prescriber asked me three questions and approved me. that is not care. in c/compounding · 35 points · 6 days ago
The shortage list is the legal hinge: the permissions that allow certain compounding to happen at scale are tied to a drug’s shortage status, which changes.
comment on [Below Spec] 61.2% on a vial that shipped with a 99% COA in c/labresults · 0 points · 10 days ago
Careful with the trend claim. Four results over two years is a very sparse series to draw a line through.
comment on [Question] does anyone get a COA from their compounding pharmacy in c/compounding · 25 points · 14 days ago
Push back: "compounded is fine because a pharmacy made it" skips every question this board exists to ask.
comment on [Discussion] we are measuring compounding at the wrong time and calling it noise in c/compounding · 7 points · 28 days ago
potency testing on the finished preparation is the thing to ask for
comment on [Below Spec] 94.1% with a 1.8% single impurity. is that the des-amido in c/labresults · 1 points · 1 months ago
Right, and a point or two between services is ordinary. It is agreement, and every month somebody posts it as a scandal.
comment on stalled for 14 weeks at 7.5mg and I refuse to panic this time in c/newbiequestions · 10 points · 2 months ago
Did you write the concentration on the vial?
comment on [Question] API source — what am I missing here in c/compounding · 29 points · 2 months ago
Asked for potency testing on the finished preparation. They had it. I had assumed they would not.
comment on compounding is the most under-discussed thing on this board in c/compounding · 12 points · 3 months ago
compounded is not generic, there is no equivalence claim
comment on anyone else notice what is kicking in around week 47 in c/newbiequestions · 33 points · 3 months ago
Gently disagree with the framing — nothing has gone wrong. Week 11 looking flat is the ordinary experience.
comment on stalled for 2 weeks at 15mg and I refuse to panic this time in c/newbiequestions · 7 points · 4 months ago
Research-use-only material is not approved for human use.
This is the answer. Everything else in the thread is elaboration on it.
comment on tried week one for 18 weeks. here is what happened. in c/newbiequestions · 74 points · 7 months ago
Bacteriostatic water contains a preservative, which is what makes repeated entry into a vial reasonable. Sterile water does not, and the two are not interchangeable for that purpose.
comment on [Discussion] can we stop arguing about 503B until somebody posts a number in c/compounding · 7 points · 7 months ago
Small fix — 503B facilities register with the regulator; 503A pharmacies are licensed by the state board. Different mechanisms.
comment on tried week one for 12 weeks. here is what happened. in c/newbiequestions · 26 points · 7 months ago
Bacteriostatic water contains a preservative, which is what makes repeated entry into a vial reasonable. Sterile water does not, and the two are not interchangeable for that purpose.
comment on three years of telehealth threads, summarised so you do not have to read them in c/compounding · 1 points · 7 months ago
That is not what patient-specific means.
Adding one thing — ask for the facility name. Most will give it, and the ones that will not have answered you.
comment on [Vendor] Homopeptide vs QSC on the same compound, same month — both cleared 98.0% in c/labresults · 47 points · 8 months ago
Do you have the trace, or only the summary?
comment on the 503A question that gets asked weekly, answered properly in c/compounding · 93 points · 9 months ago
Kept the label from every vial. When the shortage status changed, having the paper trail made the conversation much shorter.
comment on does what is actually matter or is it forum lore at this point in c/newbiequestions · 55 points · 9 months ago
What week are you in?
comment on [Question] beginner — what am I missing here in c/newbiequestions · 24 points · 11 months ago
Spent my first fortnight comparing myself to the loudest posters. Do not do that; they are not the middle of the distribution.
comment on [Discussion] we are measuring 503B at the wrong time and calling it noise in c/compounding · 22 points · 11 months ago
salt forms are the recurring argument and the answer is boring
comment on [Question] how do you actually verify 503B in c/compounding · 72 points · 1 year ago
Same view. If the intake asked you nothing, the intake was a formality and you should factor that in.
comment on 13 months in and basics are still the thing I get wrong in c/newbiequestions · 9 points · 1 year ago
the first month is a tolerance check, not a results phase
comment on the compounding question that gets asked weekly, answered properly in c/compounding · 2 points · 1 year ago
if a clinic will not name the facility, that is your answer
comment on help me understand PeptideMeter, I have read the wiki twice in c/labresults · 29 points · 1 year ago
if you are going to test, test the thing you actually received
comment on [Results] 16 weeks, 5kg, and basics were the hard part in c/newbiequestions · 111 points · 1 year ago
Nothing on this board is medical advice, and the people answering you — including me — are members with spreadsheets rather than clinicians.
pavel_kravchenko has explained this better than the wiki does, which is saying something.
comment on is it normal to get constipation at week 11 in c/newbiequestions · 1 points · 1 year ago
bacteriostatic water has a preservative, sterile water does not
comment on is it normal to get constipation at week 11 in c/newbiequestions · 1 points · 1 year ago
week two with nothing happening is normal
comment on is it normal to get constipation at week 11 in c/newbiequestions · 28 points · 1 year ago
Agreed — week two with nothing on the scale is so common it should be in the sidebar. It probably is.
comment on why does nobody talk about state board in c/compounding · 434 points · 2 years ago
Potency and sterility testing on the finished preparation are separate from any certificate covering the starting material. Ask which you are being shown.
comment on small win: what is stopped being a problem at week 72 in c/newbiequestions · 20 points · 2 years ago
research-use-only material is not approved for human use, and that belongs in every beginner thread
comment on small win: what is stopped being a problem at week 72 in c/newbiequestions · 171 points · 2 years ago
write the concentration on the vial, you will thank yourself
comment on small win: what is stopped being a problem at week 72 in c/newbiequestions · 217 points · 2 years ago
Bacteriostatic water contains a preservative, which is what makes repeated entry into a vial reasonable. Sterile water does not, and the two are not interchangeable for that purpose.
comment on someone explain 503A to me like I have not read a paper in years in c/compounding · 2 points · 2 years ago
ask what the beyond-use date is based on
comment on [Lab] 5th independent test on HJ — 99.2% on a claimed 99.0%, and the trend is the interesting part in c/labresults · 323 points · 2 years ago
Kept every report as a PDF with the batch in the filename. Two years in, it is the most useful folder I own.
comment on the Netherlands: state board, and what it actually costs here in c/compounding · 462 points · 2 years ago
What concentration is on the label, and does it match what you were expecting?
comment on [Discussion] the 503A advice in here is 2 years out of date in c/compounding · 3 points · 2 years ago
ask which facility, then ask for their testing
