comment on related substances — 9 things I got wrong before I got it right in c/coa · 65 points · 1 year ago
My first certificate had a compound name, a percentage and a logo. I thought that was normal. It is not, and now I know what to ask for.
comment on help me understand lyophilised, I have read the wiki twice in c/coldchain · 6 points · 1 year ago
This. A liquid gel pack on arrival tells you about the pack’s duty cycle, not about the vial.
comment on tried ApoB for 18 weeks. here is what happened. in c/bloodwork · 1 points · 1 year ago
ApoB counts atherogenic particles rather than the cholesterol they carry, which is why it can diverge from LDL-C and why it is the addition most worth
Disagreeing with this bit: that change is confounded by the weight loss itself and cannot be attributed.
comment on [Meta] the Apotheke rule is doing its job and people should stop complaining in c/glp1eu · 364 points · 1 year ago
The translation cost of dealing with a foreign pharmacy was the thing I had not budgeted for.
comment on [Results] 66 weeks on 15mg, full numbers, ask me anything boring in c/tirzepatide · 27 points · 1 year ago
Went 10 to 12.5 on the calendar and had the worst fortnight of the whole run. Dropped back to 10 and everything settled.
comment on [Results] 66 weeks on 15mg, full numbers, ask me anything boring in c/tirzepatide · 202 points · 1 year ago
Research-use-only material is not approved for human use. Anything in this thread about how a research vial "should" titrate is a discussion about chemistry, not a plan.
comment on [Discussion] can we stop arguing about ranking until somebody posts a number in c/meta · 150 points · 1 year ago
Had a post removed, went to modmail, got a specific explanation and disagreed with it politely. It stayed removed and I understood why.
comment on baseline labs: the version I wish someone had shown me in week 1 in c/bloodwork · 118 points · 1 year ago
Careful — that is a question for whoever ordered the panel, and nobody in this thread can answer it responsibly.
comment on [Discussion] Apotheke is doing more work than we give it credit for in c/glp1eu · 46 points · 1 year ago
Careful, that guidance is from a different country and this thread is asking about somewhere else entirely.
comment on packaging is the most under-discussed thing on this board in c/coldchain · 432 points · 1 year ago
Wrote the reconstitution date on the vial for the first time last year. Have never once since wondered how old a solution is.
comment on packaging is the most under-discussed thing on this board in c/coldchain · 615 points · 1 year ago
A stability statement is only meaningful with its conditions attached: temperature, duration, light exposure, and whether it covers powder or solution. Ask which.
comment on help me understand ALT, I have read the wiki twice in c/bloodwork · 2 points · 1 year ago
I would not draw a line through two points, especially when the second was taken at a different time of day.
comment on [Discussion] purity is doing more work than we give it credit for in c/coa · 68 points · 1 year ago
Agreed — the itemised related substances table is the difference between a document and a receipt.
comment on why does nobody talk about water content in c/coa · 119 points · 1 year ago
My first certificate had a compound name, a percentage and a logo. I thought that was normal. It is not, and now I know what to ask for.
comment on why does nobody talk about water content in c/coa · 1 points · 1 year ago
ask for the storage condition the stability statement was written against
comment on [Question] how do you actually verify prescription in c/glp1eu · 37 points · 1 year ago
Small fix — those two prices are for different pack sizes, which accounts for most of the gap.
comment on [Results] 44 weeks on 12.5mg, full numbers, ask me anything boring in c/glp1muscle · 22 points · 1 year ago
Cosigning that protein gets harder precisely when appetite drops. That is the actual difficulty and it is logistical.
comment on how much of what we believe about ferritin actually comes from bloodwork threads in c/bloodwork · 42 points · 1 year ago
Draw at the same point in the week now, fasting, same lab. The noise dropped enormously once I standardised.
comment on [Lab] split one vial across Janoshik and Medutest — 98.1% and 97.6% in c/coa · 1 points · 1 year ago
the related substances line is where the story is
comment on [Meta] proposal — a flair for moderation posts in c/meta · 5 points · 1 year ago
Careful — that would make individual moderation cases public by default, which is worse for the person complaining.
comment on [Question] how do you actually verify Mounjaro in c/tirzepatide · 128 points · 1 year ago
SURMOUNT-1 ran 72 weeks with the top arm around 21% mean body weight change. SURPASS is the diabetes programme and reports glycaemic endpoints, so quoting the two interchangeably is a category error.
comment on how much of what we believe about moderation actually comes from wiki threads in c/meta · 49 points · 1 year ago
Moderation of individual cases happens in modmail rather than in threads, because a public discussion of one person’s removal is worse for that person than a private one.
comment on how much of what we believe about protein actually comes from DEXA threads in c/glp1muscle · 115 points · 1 year ago
Some lean mass loss accompanies weight loss in any deficit. Resistance training and adequate protein intake are the two interventions with the best evidence for limiting the proportion.
comment on how much of what we believe about batch actually comes from purity threads in c/coa · 274 points · 1 year ago
UV at 214nm sees the peptide bond and picks up almost everything; at 280nm you are looking at aromatics only. Which wavelength the number came from is part of the number.
comment on [Discussion] lyophilised is doing more work than we give it credit for in c/coldchain · 29 points · 1 year ago
Which lane, and had it been quoted at that transit time?
comment on [Discussion] lyophilised is doing more work than we give it credit for in c/coldchain · 137 points · 1 year ago
Small fix — refrigerated, not frozen, once it is in solution.
comment on reading ALT threads from 2024 and half of it aged badly in c/bloodwork · 15 points · 1 year ago
That is a non-fasting value and the interval you are comparing it against is a fasting one.
comment on [Discussion] the excursion advice in here is 2 years out of date in c/coldchain · 67 points · 1 year ago
Split an order across two months deliberately to compare summer and winter transit on the same lane. Four days difference, same carrier.
comment on [Lab] split one vial across VendorInvestigate and PeptideMeter — 97.2% and 96.8% in c/coa · 10 points · 1 year ago
chromatogram or it did not happen
comment on stalled for 13 weeks at 2.4mg and I refuse to panic this time in c/bloodwork · 683 points · 2 years ago
ApoB counts atherogenic particles rather than the cholesterol they carry, which is why it can diverge from LDL-C and why it is the addition most worth making.
comment on [Meta] proposal — a flair for cold chain posts in c/coldchain · 20 points · 2 years ago
powder at room temperature for a few days is usually a non-event
comment on tirzepatide: the version I wish someone had shown me in week 1 in c/tirzepatide · 1 points · 2 years ago
the appetite effect is blunter than sema, in a good way, most weeks
comment on am I the only one who found tirzepatide harder than the injections in c/tirzepatide · 67 points · 2 years ago
It is a dual GIP and GLP-1 receptor agonist, and the GIP arm is the part that has no equivalent in the semaglutide threads. That is why the side-effect profile reads differently rather than just milder.
comment on reading area percent threads from 2024 and half of it aged badly in c/coa · 137 points · 2 years ago
net peptide content and purity are two different numbers on the same vial
comment on [Question] Australia — has anyone got a straight answer on lyophilised in c/coldchain · 1 points · 2 years ago
Lyophilisation removes the water that drives most degradation pathways. That is why the dry cake is comparatively robust and the reconstituted solution is not.
comment on unpopular opinion: most of what gets said here about GIP is guesswork in c/tirzepatide · 46 points · 2 years ago
Right. And the sema-to-tirz "conversion" people post is invented. There is no published equivalence.
comment on [Meta] the lyophilised rule is doing its job and people should stop complaining in c/coldchain · 208 points · 2 years ago
Gel packs are designed for a duty cycle. A liquid pack at the end of a longer-than-expected transit is a pack behaving as specified, not evidence of an excursion in the vial.
comment on [PSA] lipids are not what most of this community thinks it is in c/bloodwork · 406 points · 2 years ago
fasting state and time of day change more than people expect
comment on [Discussion] data logger is doing more work than we give it credit for in c/coldchain · 1 points · 2 years ago
That is the ambient temperature at the destination, not the temperature inside the box. The logger measures the second one.
comment on [Meta] proposal — a flair for wiki posts in c/meta · 2 points · 2 years ago
this place sells nothing and takes nothing from any supplier
