comment on someone explain COA to me like I have not read a paper in years in c/coa · 502 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.
Asking properly rather than in a comment on somebody else’s thread: how much of what we believe about tapering actually comes from discontinuation threads. A written…
comment on how much of what we believe about appetite return actually comes from regain threads in c/tapering · 190 points · 1 year ago
appetite comes back before the weight does
comment on [Discussion] we are measuring test results at the wrong time and calling it noise in c/labresults · 30 points · 1 year ago
date of analysis matters as much as the number

post the claim next to the result or the number floats
comment on [Lab] FGP BPC — PeptideMeter came back 99.6% against a claimed 99.0% in c/coa · 924 points · 1 year ago
Small fix — 214nm, not 280nm. It matters here because the impurity you are asking about barely absorbs at the longer wavelength.
comment on three years of COA threads, summarised so you do not have to read them in c/coa · 22 points · 1 year ago
Asked for the storage condition behind the stability statement. Got it in a sentence. It is a two-line email and almost nobody sends it.
three years of COA threads, summarised so you do not have to read them. It is the sort of thing everyone half-believes and nobody writes down. Asked GL Biochem for the…
comment on [Meta] the Janoshik rule is doing its job and people should stop complaining in c/labresults · 137 points · 1 year ago
Careful with the trend claim. Four results over two years is a very sparse series to draw a line through.
comment on [Meta] the Medutest rule is doing its job and people should stop complaining in c/labresults · 46 points · 1 year ago
Agreed on quoting the claim alongside the result. Half the arguments here are two people comparing to different reference numbers.
comment on the Janoshik thing finally clicked for me and I want to write it down in c/labresults · 0 points · 1 year ago
Split one vial between VendorInvestigate and Medutest.
noor_cardoso is right that the band matters more than the peak. Consistency across lots is the finding.
comment on [Discussion] the COA advice in here is 2 years out of date in c/coa · 1 points · 1 year ago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 [Discussion] we are measuring regain at the wrong time and calling it noise in c/tapering · 88 points · 1 year ago
Went back on after eight months away. Nobody here made me feel bad about it, which mattered more than I expected.
comment on [Meta] the area percent rule is doing its job and people should stop complaining in c/coa · 80 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 TGA question that gets asked weekly, answered properly in c/glp1aus · 1 points · 1 year ago
That is a pharmacy-level stock issue rather than a national supply issue. They feel identical and are not.
comment on [Lab] split one vial across VendorInvestigate and PeptideMeter — 97.2% and 96.8% in c/coa · 9 points · 1 year ago
identity and quantity are two questions and most documents answer one
comment on [PSA] New Zealand is not what most of this community thinks it is in c/glp1aus · 1 points · 2 years ago
Correction: that is the registration decision, not the subsidy listing. They are made by different bodies.
comment on [Discussion] the below spec advice in here is 2 years out of date in c/labresults · 46 points · 2 years ago
Push back: three tests on one lot is one lot. It tells you about that lot and almost nothing about the next one.

Careful with the trend claim. Four results over two years is a very sparse series to draw a line through.
comment on [Discussion] related substances are doing more work than we give it credit for in c/coa · 47 points · 2 years ago
Did you ask for the batch-specific document, or is this the catalogue one?
comment on [Discussion] the PeptideMeter advice in here is 2 years out of date in c/labresults · 208 points · 2 years ago
Split one vial between Medutest and VendorInvestigate. The two numbers were within half a point of each other and I stopped worrying about which lab to trust.
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 · 23 points · 2 years ago

No trophies yet. Most accounts here never get one.
Independent HPLC and mass spec. The number you get is the number they found.
