comment on small win: order records stopped being a problem at week 21 in c/vendorvetting · 383 points · 6 months ago
vendor staff must self-identify, full stop
comment on LC-MS: what the trials say vs what this community says in c/hplc · 42 points · 6 months ago
state the method: column, gradient, detection wavelength, injection volume
comment on stalled for 16 weeks at 0.5mg and I refuse to panic this time in c/glp1science · 1 points · 7 months ago
incretin physiology is receptor, the mechanism layer
comment on does LC-MS actually matter or is it forum lore at this point in c/hplc · 3 points · 7 months ago
Did they post the raw trace or just the summary?
comment on the VendorInvestigate thing finally clicked for me and I want to write it down in c/vendorvetting · 1 points · 7 months ago
Cosigning the evidence standard. Receipts make the community.
comment on [Question] New Zealand — has anyone got a straight answer on LC-MS in c/hplc · 33 points · 7 months ago
This is the "correlation is mechanism" thing again. You changed three variables at once.
comment on week 56 check-in — 12kg down, injection-site soreness manageable, one thing confusing me in c/coa · 17 points · 9 months ago
This is an urgent-care question wearing a forum question's clothes.
Yes, exactly this, and it is the bit that took me 17 weeks to accept.
comment on [Results] 87 weeks, 25kg, and receptor was the hard part in c/glp1science · 45 points · 9 months ago
Titration speed is a side-effect dial far more than an efficacy dial.
comment on switched from 0.5mg to 0.25mg and the nausea got better, not worse in c/vendorvetting · 1 points · 10 months ago
vendor staff must self-identify, full stop
comment on LC-MS: the version I wish someone had shown me in week 1 in c/hplc · 213 points · 10 months ago
Slight fix: the number was 98.7, not 98.3. Decimal point, but a fairly consequential one.
comment on [Discussion] can we stop arguing about mechanism until somebody posts a number in c/glp1science · 94 points · 10 months ago
Strongly agree. Central appetite is real but people overstate it.
comment on 19 months in and purity is still the thing I get wrong in c/coa · 344 points · 10 months ago
the method line is doing real work, not just window dressing
comment on genuine question about integration that I am slightly embarrassed to ask in c/hplc · 111 points · 11 months ago
Tracking number removed. It identifies both ends of a shipment.
comment on does purity actually matter or is it forum lore at this point in c/hplc · 218 points · 11 months ago
Retitled to remove editorialising. Put the evidence in the body.
comment on [Vendor] WXT order #17 — Germany, 9 days, no drama, receipts inside in c/glp1science · 159 points · 1 year ago
Flair changed to match the content. Read the sidebar before posting next time and we are square.
comment on [Discussion] we are measuring integration at the wrong time and calling it noise in c/hplc · 7 points · 1 year ago
Strongly agree. Largest single impurity tells a different story than total purity.
comment on [Discussion] can we stop arguing about PeptideMeter until somebody posts a number in c/vendorvetting · 161 points · 1 year ago
did they reship, credit, or ghost you?
comment on [Discussion] we are measuring appetite at the wrong time and calling it noise in c/glp1science · 1 points · 1 year ago
amylin is not GLP-1, posts conflating them get corrected
comment on tried method development for 12 weeks. here is what happened. in c/hplc · 175 points · 1 year ago
This is an urgent-care question wearing a forum question's clothes. Please contact a clinician rather than waiting for replies.
