split one vial across Janoshik and Medutest — 95.1% and 99.3%. I will put the method line and the batch identifier up front because that is what makes this checkable.…

comment on [Discussion] we are measuring plateau at the wrong time and calling it noise in c/semaglutide · 18 points · 1 year ago
Strongly agree on protein. It did more for my fatigue than any of the things I bought to fix my fatigue.
comment on three years of weekly dosing threads, summarised so you do not have to read them in c/semaglutide · 158 points · 1 year ago
The escalation schedule in the trials existed to keep people on the drug.
Adding one thing to this: the appetite effect and the scale run on separate clocks, so both halves can be true at once.
comment on [Meta] proposal — a flair for tracking posts in c/dosinglogs · 26 points · 1 year ago
a log with no dates is a story
comment on the semaglutide thing finally clicked for me and I want to write it down in c/semaglutide · 31 points · 1 year ago
nausea that arrives on day two and fades by day four is the standard shape
comment on integration — 22 things I got wrong before I got it right in c/hplc · 477 points · 1 year ago
Gave the same trace to two people I trust and got two integrations about a point apart. That was the most educational afternoon I have had here.
comment on the food noise question that gets asked weekly, answered properly in c/semaglutide · 1 points · 1 year ago
Genuine question — is the appetite effect still there, or is it just the scale that has paused?
comment on [Question] area percent — what am I missing here in c/coa · 114 points · 1 year ago
a certificate with no method line is decorative
comment on [Lab] 9th independent test on QYB — 97.7% on a claimed 97.0%, and the trend is the interesting part in c/retatrutide · 35 points · 1 year ago
Agreed, and the glucagon arm is exactly why the comparison threads do not work.
Disagree with this specific inference. A 48-week readout does not tell you the shape of the curve after it.
comment on [Question] is 99.0% actually fine or am I being sold a rounding error in c/coa · 75 points · 1 year ago
batch number, date of analysis, method, individual impurities — that is the minimum set
comment on [PSA] area percent is not what most of this community thinks it is in c/coa · 1 points · 1 year 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 [Meta] proposal — a flair for Ozempic posts in c/semaglutide · 16 points · 1 year ago
Week 17: 3kg down, food noise basically gone since about week 9, and the honest headline is that nothing dramatic happened. It was boring and it worked.
comment on the LC-MS question that gets asked weekly, answered properly in c/hplc · 180 points · 1 year ago
Can you post the trace with the axes labelled?
comment on [Discussion] the purity advice in here is 3 years out of date in c/coa · 279 points · 1 year ago
Asked KP for the batch-specific certificate and had the full document — batch, date, method line naming the column — inside six hours. That is now my baseline for everybody.
comment on [Question] is 98.1% actually fine or am I being sold a rounding error in c/hplc · 44 points · 1 year ago
That figure cannot be quoted to two decimals off that baseline. The precision is not in the data.
comment on unpopular opinion: most of what gets said here about certificate of analysis is guesswork in c/coa · 167 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 · 4 points · 1 year ago
Agreed on asking for the storage condition. It is one line and it changes how you read the entire stability claim.
comment on am I the only one who found triple agonist harder than the injections in c/retatrutide · 45 points · 1 year ago
That is body weight change, not fat mass. The trials report the first and people quote it as the second.
comment on the chargeback thing finally clicked for me and I want to write it down in c/cryptopay · 2 points · 1 year ago
The transaction hash is the canonical receipt: it is public, verifiable by either party, and it is what a support query should quote.
comment on why does nobody talk about water content in c/coa · 119 points · 1 year ago
redact your own name, never the batch details
comment on the UK: network, and what it actually costs here in c/cryptopay · 113 points · 1 year ago
A test transaction costs one extra network fee and verifies the address, the network and the recipient’s crediting process before the main amount moves.
comment on anyone else notice weekly dosing kicking in around week 33 in c/semaglutide · 659 points · 1 year ago
Careful. A four-week stall is inside normal variation and treating it as failure is how people escalate for no reason.
comment on my ferritin moved and I cannot work out whether tracking is why in c/dosinglogs · 167 points · 1 year ago
Same. Waist monthly was the column I added late and wish I had started with.
comment on [Lab] MKM cagri — Medutest came back 97.2% against a claimed 97.0% in c/hplc · 88 points · 1 year ago
the column has a history and it shows in the peak shape
comment on [Lab] split one vial across Janoshik and Medutest — 98.1% and 97.6% in c/coa · 4 points · 1 year ago
batch number, date of analysis, method, individual impurities — that is the minimum set
comment on [Question] triple agonist — what am I missing here in c/retatrutide · -35 points · 1 year ago
Which phase 2 arm are you quoting, and at what week?
comment on three years of water content threads, summarised so you do not have to read them in c/coa · 86 points · 1 year ago
Did you get the chromatogram or only the summary line?
comment on reading chromatogram threads from 2024 and half of it aged badly in c/hplc · 17 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 reading chromatogram threads from 2024 and half of it aged badly in c/hplc · 29 points · 1 year ago
Same method at both labs, or two different gradients?
Disagreeing with this bit: that spread is ordinary inter-lab variance, not a disagreement about the material.
comment on [Meta] the area percent rule is doing its job and people should stop complaining in c/coa · 25 points · 1 year ago
ask for the storage condition the stability statement was written against
comment on [Discussion] can we stop arguing about purity until somebody posts a number in c/coa · 151 points · 2 years ago
Right, and net peptide content is where the counterion and the water go. Both numbers can be honest and very different.
comment on [Lab] split one vial across Janoshik and Medutest — 95.1% and 99.3% in c/retatrutide · 1 points · 2 years ago
nothing here is available as a prescription product, so read every thread with that in mind
comment on [Lab] split one vial across Janoshik and Medutest — 95.1% and 99.3% in c/retatrutide · 55 points · 2 years ago
Is that the 48-week figure or an earlier readout?
comment on [Lab] split one vial across Janoshik and Medutest — 95.1% and 99.3% in c/retatrutide · 182 points · 2 years ago
What is the source for that figure — the published paper or a summary of it?
comment on [Question] how do you actually verify weekly update in c/dosinglogs · 64 points · 2 years ago
Logged the missed weeks as blanks rather than skipping them. The gaps turned out to be the informative part.
comment on stalled for 7 weeks at 10mg and I refuse to panic this time in c/retatrutide · 0 points · 2 years ago
Same read.
This is the sentence the rest of the board should read first. Phase 2 is not a label.
comment on [Discussion] we are measuring network at the wrong time and calling it noise in c/cryptopay · 42 points · 2 years ago
the memo field matters on the chains that use one
comment on someone explain phase 2 to me like I have not read a paper in years in c/retatrutide · 18 points · 2 years ago
Went up slowly, deliberately, because everything on this board says the escalation is where trouble lives. Uneventful so far and I am not going to pretend that is a finding.
comment on someone explain phase 2 to me like I have not read a paper in years in c/retatrutide · 36 points · 2 years ago
Has anyone posted an independent test on this compound recently?
comment on someone explain phase 2 to me like I have not read a paper in years in c/retatrutide · 304 points · 2 years ago
the glucagon component is why the metabolic story reads differently
