comment on genuine question about MASH that I am slightly embarrassed to ask in c/survodutide · 1 points · 1 year ago
dual GLP-1 and glucagon agonist, and the glucagon arm is the story
Disagreeing with this bit: that number comes from a different programme with a different population.
comment on why does nobody talk about tendon in c/bpc157 · 25 points · 1 year ago
Was there identity confirmation, or only a purity figure?
comment on [Question] integration — what am I missing here in c/hplc · 7 points · 1 year ago
Agreed. Two analysts, one trace, two integration choices, and a spread that has nothing to do with the vial.
comment on someone explain reflux to me like I have not read a paper in years in c/sideeffects · 17 points · 1 year ago
Nobody warned me about muscle cramps and I would have liked the warning. It was not dangerous, it was just deeply unpleasant and completely unexpected.
comment on someone explain reflux to me like I have not read a paper in years in c/sideeffects · 110 points · 1 year ago
Reflux was the one that got me. Stopped eating in the three hours before bed and it went from nightly to almost never.
comment on someone explain reflux to me like I have not read a paper in years in c/sideeffects · 201 points · 1 year ago
Has anything else changed in the same window?
comment on [Question] is 97.4% actually fine or am I being sold a rounding error in c/hplc · 3 points · 1 year ago
Resolution between two peaks depends on retention, selectivity and efficiency. A shallower gradient buys retention and usually resolution, at the cost of peak width and run time.
comment on what would you tell week-1 you about glucagon in c/retatrutide · 444 points · 1 year ago
Kept a log specifically because there is so little published. It is one person and it is not data.
comment on does method development actually matter or is it forum lore at this point in c/hplc · 7 points · 1 year ago
Not convinced by that integration. Dropping the baseline there absorbs part of the shoulder into the main peak.
comment on [Vendor] HJ vs QYB on the same compound, same month — both cleared 97.0% in c/coa · 1 points · 1 year ago
Spent four months confusing area% and mass% in every post I made here. One explainer thread and it clicked permanently.
comment on does method development actually matter or is it forum lore at this point in c/hplc · 133 points · 1 year ago
Carryover from a previous high-concentration injection looks exactly like a small impurity. The blank injection is four minutes and it removes the ambiguity entirely.
comment on [Vendor] HJ vs QYB on the same compound, same month — both cleared 97.0% in c/coa · -31 points · 1 year ago
Does the lot on the vial match the lot on the page?
comment on [Question] how do you actually verify sequence in c/bpc157 · 3 points · 1 year ago
the tendon claims are the most repeated and the least evidenced
comment on how much of what we believe about purity actually comes from related substances threads in c/coa · 105 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 how much of what we believe about purity actually comes from related substances threads in c/coa · 128 points · 1 year ago
I would not read a rounded figure as evasive. Plenty of documents round to one decimal as house style.
comment on three years of MASH threads, summarised so you do not have to read them in c/survodutide · 37 points · 1 year ago
do not import intuitions from the obesity programmes
comment on gallbladder: the version I wish someone had shown me in week 1 in c/sideeffects · -12 points · 1 year ago
fatigue plus low intake is usually just low intake
comment on [Lab] 10th independent test on GL Biochem — 99.4% on a claimed 99.0%, and the trend is the interesting part in c/researchpeptides · 18 points · 1 year ago
Asked CPC which lines they keep in regional stock versus make to order and got a clear split. It changed what I ordered.
comment on tendon: what the trials say vs what this community says in c/bpc157 · 11 points · 1 year ago
Small fix — fifteen residues, not seventeen. The sequence is public and easy to check.
comment on three years of gradient threads, summarised so you do not have to read them in c/hplc · 112 points · 1 year ago
area percent is relative to what the detector saw and nothing else
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 · 202 points · 1 year ago
Is that the 48-week figure or an earlier readout?
comment on genuine question about LC-MS that I am slightly embarrassed to ask in c/hplc · 166 points · 1 year ago
Cosigning the wavelength point. Half the disagreements in this board are two people looking at different detectors.
comment on the HPLC thing finally clicked for me and I want to write it down in c/hplc · 2 points · 1 year ago
Method questions stay here; supplier claims go to c/vendorvetting with a document attached.
peak_area_pete is right — the integration choice is a decision and it should be stated alongside the result.
comment on the HPLC thing finally clicked for me and I want to write it down in c/hplc · 0 points · 1 year ago
Small fix — 214nm, not 210. It matters for the comparison you are making with the other run.
comment on does fraud actually matter or is it forum lore at this point in c/scamalerts · 1 points · 1 year ago
Disagree with naming anyone on that basis. One person’s bad month is not a pattern and the sidebar exists for this exact reason.
comment on 4 months in and hepatic fat is still the thing I get wrong in c/survodutide · -26 points · 1 year ago
fibrosis improvement without worsening steatohepatitis is the phrase to learn
comment on three years of regulatory threads, summarised so you do not have to read them in c/bpc157 · 24 points · 1 year ago
That claim traces back to a single preclinical paper that says something considerably narrower.
comment on [Discussion] the pharmacology advice in here is 3 years out of date in c/glp1science · 572 points · 1 year ago
Went looking for human data on a mechanism everybody here asserts. Found preclinical work and one small study. That was clarifying.
comment on unpopular opinion: most of what gets said here about pharmacology is guesswork in c/glp1science · 3 points · 1 year ago
receptor agonism is not the same as receptor activation in every tissue
comment on help me understand lyophilised, I have read the wiki twice in c/coldchain · 35 points · 1 year ago
the excursion that matters is the one after reconstitution
comment on [Lab] WXT cagri — PeptideMeter came back 97.8% against a claimed 97.0% in c/hplc · 1 points · 1 year ago
Resolution between two peaks depends on retention, selectivity and efficiency. A shallower gradient buys retention and usually resolution, at the cost of peak width and run time.
comment on [Lab] WXT reta — PeptideMeter came back 97.7% against a claimed 97.0% in c/retatrutide · 264 points · 1 year ago
What do you think the glucagon component is adding, specifically?
comment on [Question] how do you actually verify exit scam in c/scamalerts · 17 points · 1 year ago
What dates are we talking about — order, payment, last contact?
comment on [Question] data logger — what am I missing here in c/coldchain · 163 points · 1 year ago
Regional stock changes the question rather than answering it: shorter lanes mean less exposure and fewer variables, which is why the warehouse question is worth asking before ordering in summer.
comment on how much of what we believe about scam actually comes from PDF metadata threads in c/scamalerts · -34 points · 1 year ago
Agreed. The clone copies the front page and never the paperwork, because the paperwork is the expensive part.
comment on how much of what we believe about scam actually comes from PDF metadata threads in c/scamalerts · 7 points · 1 year ago
check the domain character by character before you check anything else
comment on help me understand heart rate, I have read the wiki twice in c/sideeffects · 47 points · 1 year ago
Severe or persistent abdominal pain sits outside the pattern this board can usefully discuss. The honest answer there is that it needs someone who can examine you.
comment on the fake COA question that gets asked weekly, answered properly in c/scamalerts · 18 points · 1 year ago
never accuse an individual, describe what happened to you
Adding the practical version: buy small from anyone new, test it, then decide.
comment on the nausea thing finally clicked for me and I want to write it down in c/sideeffects · 1 points · 1 year ago
Yes — the day-two-to-day-four window is so consistent across this board that it is almost diagnostic.
comment on reflux — 5 things I got wrong before I got it right in c/sideeffects · -36 points · 1 year ago
The fatigue turned out to be that I was eating about a third of what I thought I was. Tracked it for a week and the mystery evaporated.
