Question in the title, detail here: genuine question about HPLC that I am slightly embarrassed to ask. MKM sent me the column, the gradient and the theoretical mass…

comment on [Meta] the Apotheke rule is doing its job and people should stop complaining in c/glp1eu · 21 points · 1 year ago
pharmacy margins are regulated differently in each country
comment on how much of what we believe about scam actually comes from PDF metadata threads in c/scamalerts · 127 points · 1 year ago
Careful. What you are describing is a delayed shipment, and this board should not turn that into an accusation without more.
comment on my ferritin moved and I cannot work out whether FFMI is why in c/glp1muscle · 1 points · 1 year ago
Correction: those scans are from different machines, and the difference you are describing is within the measurement error.
comment on the fake COA question that gets asked weekly, answered properly in c/scamalerts · 1 points · 1 year ago
Not convinced. A payment window that closed is a payment window, not evidence of intent.
comment on [Lab] split one vial across PeptideMeter and VendorInvestigate — 96.8% and 99.1% in c/hplc · 235 points · 1 year ago
Disagree. Inter-lab spread of a point or two on this assay is ordinary and calling it a discrepancy misleads people.
comment on why does nobody talk about gradient in c/hplc · 624 points · 1 year ago
Mass spectrometry answers identity. UV purity answers relative quantity under the run conditions. A document with one and not the other is answering half the question, and the half it answers should be stated.
comment on unpopular opinion: most of what gets said here about integration is guesswork in c/hplc · 8 points · 1 year ago
Bought a second-hand instrument and learned more in six months of fixing it than in three years of reading traces.
comment on [Question] is 98.9% actually fine or am I being sold a rounding error in c/scamalerts · 3 points · 1 year ago
screenshots are not evidence, dates and documents are
comment on [Lab] MKM cagri — Medutest came back 97.2% against a claimed 97.0% in c/hplc · 141 points · 1 year ago
area percent is relative to what the detector saw and nothing else
comment on [Question] is 95.1% actually fine or am I being sold a rounding error in c/scamalerts · 8 points · 1 year ago
Not convinced. A payment window that closed is a payment window, not evidence of intent.

two labs, two gradients, two honest answers

Same method at both labs, or two different gradients?

system suitability before you believe any number on the run
comment on [Results] 27 weeks on 7.5mg, full numbers, ask me anything boring in c/glp1muscle · 23 points · 2 years ago
Agreed — protein and resistance training. Everything else in these threads is a rounding error on those two.
comment on pharmacy — 20 things I got wrong before I got it right in c/glp1eu · 206 points · 2 years ago
Cross-border prescription recognition exists under EU rules but is conditional and narrower than commonly assumed, with requirements about the prescription’s form and content.
comment on [Discussion] can we stop arguing about fraud until somebody posts a number in c/scamalerts · 368 points · 2 years ago
Correction: that domain is one character different from the one you posted, which is rather the point of this thread.
comment on [Discussion] we are measuring scam at the wrong time and calling it noise in c/scamalerts · 24 points · 2 years ago
the review page nobody can find on any other site is a warning
comment on [Discussion] fake COA is doing more work than we give it credit for in c/scamalerts · 274 points · 2 years ago
Cosigning the domain check. Character by character, every time, and paste it rather than typing it.
comment on [Lab] 18th independent test on SWB — 99.4% on a claimed 99.0%, and the trend is the interesting part in c/hplc · 47 points · 2 years ago
axis labels or the trace is decoration
comment on [Lab] split one vial across Medutest and Janoshik — 96.2% and 97.4% in c/scamalerts · -29 points · 2 years ago
Is this a shop, a group buy, or an individual reseller? They fail in different ways.
