comment on [Below Spec] 61.2% on a vial that shipped with a 99% COA in c/labresults · 1 points · 9 days ago
This.
Disagreeing with this line: that gap is ordinary variance, not a contradiction between the lab and the certificate.
comment on [Discussion] the compounding gap was a symptom, not a solution in c/compounding · 3 points · 10 days ago
Who is the prescriber, and are they the same organisation as the pharmacy?
comment on switched from compounded to brand and the titration reset itself in c/compounding · 1 points · 20 days ago
What is the beyond-use date and what is it based on?
comment on [Below Spec] 88% is not "basically fine" and i am tired of that reply in c/labresults · 1 points · 21 days ago
Area percent or net peptide content?
comment on [Below Spec] 88% is not "basically fine" and i am tired of that reply in c/labresults · 26 points · 23 days ago
If the report gives a mass spectrum as well as UV purity, say so. Identity and relative quantity are separate claims and the log tracks both.
comment on [PeptideMeter] ERP tirz 15mg — 98.4% and a very clean trace in c/labresults · 1 points · 1 months ago
Small fix — same supplier, different lot. The two rows in the log are not the same batch.
comment on [Discussion] the telehealth advice in here is 3 years out of date in c/compounding · 15 points · 1 months ago
That is not what patient-specific means. It refers to the prescription, not to a customisation of the formula.
comment on [Below Spec] 94.1% with a 1.8% single impurity. is that the des-amido in c/labresults · 7 points · 1 months ago
Push back: three tests on one lot is one lot. It tells you about that lot and almost nothing about the next one.
comment on why does nobody talk about telehealth in c/compounding · 4 points · 1 months ago
Did they name the facility?
comment on genuine question about lost money that I am slightly embarrassed to ask in c/darkspot · 41 points · 2 months ago
the thing that went wrong is usually procedural, not dramatic
comment on [Discussion] can we stop arguing about cycle until somebody posts a number in c/glp1women · -31 points · 2 months ago
symptom patterns can track the cycle rather than the dose
comment on does below spec actually matter or is it forum lore at this point in c/darkspot · 37 points · 2 months ago
going up too fast is the most repeated regret on this board
comment on state board — 3 things I got wrong before I got it right in c/compounding · 5 points · 2 months ago
That figure is the starting material purity, not the finished preparation potency. Two different tests.
comment on [Question] how do you actually verify batch in c/labresults · 5 points · 3 months ago
A series across separate lots estimates a process. Repeat tests on one lot estimate the measurement. Both are useful and they answer different questions.
comment on [Question] how do you actually verify batch in c/labresults · 3 points · 3 months ago
This. The trend across separate lots is the number that tells you about a process rather than a vial.
comment on [Lab] TFC cagri — Janoshik came back 98.1% against a claimed 98.0% in c/cagrilintide · 54 points · 3 months ago
Amylin is co-secreted with insulin and acts on satiety and gastric emptying through its own receptor complexes. An amylin analogue is therefore not a variant of an incretin agonist — it is a different signalling axis.
comment on Canada: API source, and what it actually costs here in c/compounding · 26 points · 4 months ago
Same view. If the intake asked you nothing, the intake was a formality and you should factor that in.
comment on [PSA] regret is not what most of this community thinks it is in c/darkspot · 16 points · 4 months ago
somebody will read this at the point you were at, and it will help
comment on [Results] 17 weeks, 6kg, and cagrilintide was the hard part in c/cagrilintide · 136 points · 6 months ago
amylin and GLP-1 are not redundant pathways
comment on [Results] 17 weeks, 6kg, and cagrilintide was the hard part in c/cagrilintide · 1 points · 6 months ago
Monotherapy arm or combination arm?
comment on unpopular opinion: most of what gets said here about test results are guesswork in c/labresults · 70 points · 6 months ago
The template is vendor, compound, batch, service, claim, result, and who paid. Every one of those fields exists because a result missing it has been argued about here before.
comment on [Results] 17 weeks, 6kg, and cagrilintide was the hard part in c/cagrilintide · 186 points · 6 months ago
phase 3 data will change most of what gets said here
comment on [Discussion] we are measuring telehealth at the wrong time and calling it noise in c/compounding · 3 points · 6 months ago
What concentration is on the label, and does it match what you were expecting?
comment on [Discussion] we are measuring telehealth at the wrong time and calling it noise in c/compounding · 2 points · 6 months ago
Nothing in this thread is medical advice, and the choice between arrangements is one for you and a prescriber who knows your history.
comment on [Lab] split one vial across VendorInvestigate and PeptideMeter — 99.1% and 96.8% in c/labresults · 22 points · 7 months ago
Cosigning on saying who paid. It is the whole basis on which this log is worth anything.
comment on Medutest — 16 things I got wrong before I got it right in c/labresults · 6 points · 7 months ago
one result is a data point, agreement between two services is evidence
comment on reading REDEFINE threads from 2024 and half of it aged badly in c/cagrilintide · 46 points · 7 months ago
Yes. The combination is where the interesting effect sizes are, and the monotherapy arms read very differently.
comment on [Discussion] the shortage list advice in here is 3 years out of date in c/compounding · 35 points · 8 months ago
the shortage list is the whole legal hinge and people skip it
comment on reading 503A threads from 2024 and half of it aged badly in c/compounding · 4 points · 11 months ago
hassan_chowdhury is right about the concentration trap.
Adding one thing — ask for the facility name. Most will give it, and the ones that will not have answered you.
comment on [Discussion] the test results advice in here is 2 years out of date in c/labresults · 10 points · 11 months ago
Cosigning on saying who paid. It is the whole basis on which this log is worth anything.
comment on [Discussion] the test results advice in here is 2 years out of date in c/labresults · 4 points · 11 months ago
Tested three lots over a year rather than three vials from one lot. Cost the same and told me something completely different.
comment on someone explain fertility to me like I have not read a paper in years in c/glp1women · 60 points · 11 months ago
Same.
Agreed, and the research gap being real rather than imagined is worth saying out loud.
comment on how much of what we believe about PeptideMeter actually comes from batch threads in c/labresults · 1 points · 12 months ago
Have now spent more on testing than on some of the orders. No regrets — the log is the reason I can buy without agonising.
comment on three years of regret threads, summarised so you do not have to read them in c/darkspot · 0 points · 1 year ago
I would not generalise from one bad month to a rule. The rest of your process sounds fine.
comment on someone explain telehealth to me like I have not read a paper in years in c/compounding · 8 points · 1 year ago
Paid noticeably more at one clinic than another for what turned out to be the same facility behind both.
comment on genuine question about telehealth that I am slightly embarrassed to ask in c/compounding · -8 points · 1 year ago
salt forms are the recurring argument and the answer is boring
comment on PeptideMeter is the most under-discussed thing on this board in c/labresults · 2 points · 1 year ago
one result is a data point, agreement between two services is evidence
comment on [Question] Spain — has anyone got a straight answer on 503B in c/compounding · 30 points · 1 year ago
503A or 503B — do you know which?
comment on [Question] Spain — has anyone got a straight answer on 503B in c/compounding · 6 points · 1 year ago
Small fix — 503B facilities register with the regulator; 503A pharmacies are licensed by the state board. Different mechanisms.
comment on [Question] Spain — has anyone got a straight answer on 503B in c/compounding · 11 points · 1 year ago
Asked for the beyond-use date basis and got a real answer with a stability reference attached. Not universal, apparently.
