comment on France: chromatogram, and what it actually costs here in c/hplc · 1 points · 4 months ago
area% and mass% are not the same and this whole post conflates them
comment on someone explain HPLC to me like I have not read a paper in years in c/hplc · 78 points · 4 months ago
co-elution is real and chromatogram is usually not enough to resolve it
comment on 15mg vs GIP — genuinely asking which matters more in c/tirzepatide · 8 points · 5 months ago
Hard agree. The food noise disappears differently on the two compounds.

phase 2 numbers are not maintenance numbers, cite the trial

TRIUMPH phase 2 showed 97.4% weight loss but the injection-site soreness profile on the highest arm was rough. Phase 2 != phase 3.

TRIUMPH phase 2 showed 98.9% weight loss but the sulphur burps profile on the highest arm was rough. Phase 2 != phase 3.

the dosing is steep, the injection-site soreness reports are real, and nobody knows the human safety yet
Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.
comment on batch vs test results — genuinely asking which matters more in c/labresults · 1 points · 5 months ago
sample of one, say so
comment on [Question] chromatogram — what am I missing here in c/hplc · 11 points · 5 months ago
the detector wavelength matters more than people think
comment on why does nobody talk about triple agonist in c/retatrutide · 1 points · 5 months ago
Strongly agree. Heart rate escalation needs the actual data, not impressions.
comment on [Vendor] QST order #13 — Spain, 5 days, no drama, receipts inside in c/customs · 28 points · 6 months ago
You have restated the marketing copy. What is the actual substance here.
comment on ranking: what the trials say vs what this community says in c/meta · -5 points · 6 months ago
Yeah, the evidence standard works.
comment on switched from 1.0mg to 0.5mg and the injection-site soreness got better, not worse in c/maintenancephase · 31 points · 7 months ago
the lowest dose you can stay on is not the lowest dose that works
comment on does personal import actually matter or is it forum lore at this point in c/customs · 42 points · 7 months ago
Week 89 for me and the honest summary is: 25kg down, reflux manageable, and I have thought about food maybe four times today.
comment on [Results] 46 weeks on 10mg, full numbers, ask me anything boring in c/labresults · 45 points · 7 months ago
Crossposting this to c/bloodwork because the people who need it are not reading this community.
Disagree on that part. 95.1% and 99.3% on the same vial is normal.
comment on switched from 7.5mg to 15mg and the nausea got better, not worse in c/tirzepatide · 45 points · 7 months ago
the appetite change on tirz is more than just reduced hunger, it is different machinery
comment on three years of Medutest threads, summarised so you do not have to read them in c/labresults · 5 points · 7 months ago
Is that 95.1% area or mass?
comment on am I the only one who found TRIUMPH harder than the injections in c/retatrutide · 176 points · 8 months ago
TRIUMPH phase 2 showed 97.4% weight loss but the fatigue profile on the highest arm was rough. Phase 2 != phase 3.
comment on [Lab] 24th independent test on QSC, and the trend is the interesting part in c/hplc · 79 points · 8 months ago
Dead space in the needle hub holds a small but non-trivial volume. On low-volume draws that can be several units.
