Was there a memo or tag requirement on that chain?
comment on acetate counterion is why your 10mg vial has 8.7mg of peptide in c/coa · 1 points · 14 days ago
The PDF creation date being later than the analysis date is usually a re-issue or a re-export. It is worth one question and it is not evidence of anything on its own.
comment on PDF producer string says the file was made in a browser. is that normal in c/coa · -5 points · 16 days ago
Sent one vial to Medutest and VendorInvestigate. 98.1% and a claimed 98.0%. Cost me more than the vial and I would do it again.
comment on [Lab] my running table: 34 tests, 11 vendors, three years in c/labresults · 6 points · 19 days ago
I would not post that as a finding.
This is why the template has a batch field. Without it the result is about a vial nobody can identify.
comment on everyone here has a spreadsheet, do i need a spreadsheet in c/newbiequestions · 8 points · 24 days ago
Agreed that appetite moves before the scale. Knowing that in advance saves a lot of week-three panic.
comment on [Below Spec] 88% is not "basically fine" and i am tired of that reply in c/labresults · 18 points · 24 days ago
area percent unless the report says otherwise
comment on [Vendor] HJ order #7 — Denmark, 4 days, no drama, receipts inside in c/cryptopay · 36 points · 26 days ago
gas is not the supplier’s fee
comment on the province question that gets asked weekly, answered properly in c/glp1canada · 8 points · 27 days ago
Same view — private and provincial plans are genuinely different processes with different appeal routes.
comment on [Discussion] we need a standard template or these posts are unsearchable in c/labresults · 5 points · 29 days ago
BCH came back 97.7% on a claimed 97.5%, which is agreement not a discrepancy
comment on the normal thing finally clicked for me and I want to write it down in c/newbiequestions · 280 points · 1 months ago
Research-use-only material is not approved for human use. That is a plain statement of regulatory fact and it belongs in every beginner thread.
comment on reading gas fees threads from 2024 and half of it aged badly in c/cryptopay · 67 points · 1 months ago
Careful, that address format belongs to a different chain and sending to it would not end well.
comment on [Meta] proposal — a flair for PeptideMeter posts in c/labresults · 56 points · 1 months ago
Date of analysis anchors the result to a manufacturing period. A two-year-old result is evidence about two years ago and should be read that way.
comment on how much of what we believe about area percent actually comes from COA threads in c/coa · 292 points · 1 months 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 genuine question about area percent that I am slightly embarrassed to ask in c/coa · 0 points · 2 months ago
Small fix — 214nm, not 280nm. It matters here because the impurity you are asking about barely absorbs at the longer wavelength.
comment on [Lab] split one vial across Medutest and Janoshik — 97.6% and 95.1% in c/labresults · 50 points · 2 months ago
Fourth lot from the same supplier in the log now and the band has been tight the whole way. That consistency is the actual finding.
comment on confirmations — 20 things I got wrong before I got it right in c/cryptopay · 7 points · 2 months ago
Was there a memo or tag requirement on that chain?
comment on [Discussion] the crypto advice in here is 3 years out of date in c/cryptopay · 3 points · 3 months ago
screenshot the transaction hash, not the wallet balance
comment on [Question] certificate of analysis — what am I missing here in c/coa · 190 points · 3 months ago
LC-MS gives you identity; UV purity gives you a relative quantity. A document with the first and not the second, or the reverse, is answering half the question.
comment on [Question] Canada — what am I missing here in c/glp1canada · 1 points · 3 months ago
employer plans have their own criteria and their own appeals
comment on reading certificate of analysis threads from 2024 and half of it aged badly in c/coa · 102 points · 3 months ago
That is the catalogue certificate rather than the batch-specific one. Same layout, completely different status.
comment on anyone else notice what is kicking in around week 47 in c/newbiequestions · 20 points · 3 months ago
Is this your first step up or the starting dose?
comment on [PSA] private plan is not what most of this community thinks it is in c/glp1canada · 1 points · 3 months ago
special authorization forms are published, read them before applying
comment on [Vendor] KP order #4 — Ireland, 13 days, no drama, receipts inside in c/cryptopay · 1 points · 3 months ago
nobody legitimate needs the payment in the next ten minutes
purity_pedant is right about confirmations. "Sent" is not a status.
comment on [Vendor] KP order #4 — Ireland, 13 days, no drama, receipts inside in c/cryptopay · 9 points · 3 months ago
Memo requirements are chain-specific. The chain you are describing does not use one.
comment on [Discussion] we are measuring confirmations at the wrong time and calling it noise in c/cryptopay · 15 points · 4 months ago
Is the fee you are describing the network fee or something the supplier added?
comment on someone explain gas fees to me like I have not read a paper in years in c/cryptopay · 3 points · 4 months ago
Confirmations are the count of blocks built on top of the one containing your transaction. Until there are some, the transaction is not settled in any meaningful sense.
comment on [Lab] 10th independent test on ERP — 97.2% on a claimed 97.0%, and the trend is the interesting part in c/coa · 27 points · 6 months ago
Area percent is the peak area of your compound over the total integrated area, at one wavelength, on one gradient. It is a relative measure of what the detector saw, not a mass fraction of the vial.
comment on tried week one for 18 weeks. here is what happened. in c/newbiequestions · 52 points · 7 months ago
Appetite change and weight change are different measurements on different timescales. The first is usually noticed first and the second lags it.
comment on [Lab] split one vial across VendorInvestigate and PeptideMeter — 99.1% and 96.8% in c/labresults · 132 points · 7 months ago
That service reports area percent by default. Worth stating, since the thread has been comparing it to a mass figure.
comment on [Question] how do you actually verify escrow in c/cryptopay · 36 points · 7 months ago
Same. Asking which networks are accepted before ordering has saved me twice.
comment on Medutest — 16 things I got wrong before I got it right in c/labresults · 62 points · 7 months ago
inter-lab variance runs a point or two, plan your outrage accordingly
comment on Medutest — 16 things I got wrong before I got it right in c/labresults · 7 points · 7 months ago
Area percent or net peptide content?

That service reports area percent by default. Worth stating, since the thread has been comparing it to a mass figure.
comment on [Question] how do you actually verify crypto in c/cryptopay · 11 points · 9 months ago
send a test amount first if the total is large
Adding the cheap insurance — test amount first on anything large.
comment on [Discussion] the certificate of analysis advice in here is 3 years out of date in c/coa · 39 points · 9 months ago
the related substances line is where the story is
comment on [Discussion] can we stop arguing about USDC until somebody posts a number in c/cryptopay · 43 points · 10 months ago
Small fix — that is the network fee, not a supplier charge. The distinction matters for the complaint you are making.
comment on [Question] batch — what am I missing here in c/coa · 119 points · 11 months ago
Small fix — 214nm, not 280nm. It matters here because the impurity you are asking about barely absorbs at the longer wavelength.
comment on how much of what we believe about PeptideMeter actually comes from batch threads in c/labresults · 24 points · 12 months ago
First result I ever posted here got asked for the batch number and the claim. Fair, and my posts have been better ever since.
comment on someone explain chargeback to me like I have not read a paper in years in c/cryptopay · 6 points · 12 months ago
A token symbol identifies an asset, not a network. The same symbol commonly exists on several chains with incompatible address formats, and sending across that boundary is generally unrecoverable.
