comment on [Discussion] we are measuring UK at the wrong time and calling it noise in c/glp1uk · 80 points · 10 months ago
The evidence standard in c/vendorvetting gets called too strict about once a month, and every time, the thread ends with the complainant agreeing.
comment on [Lab] 23th independent test on QSC, and the trend is the interesting part in c/glp1uk · 5 points · 11 months ago
That is net peptide content, not purity. Different number, different meaning.
comment on 21 months in and HPLC is still the thing I get wrong in c/hplc · 1 points · 11 months ago
Not convinced. The evidence does not support that reading.

area% and mass% are not the same and this whole post conflates them

IANAD and neither is anyone upvoting this
comment on does purity actually matter or is it forum lore at this point in c/hplc · 187 points · 11 months ago
instrument quality is less important than analyst consistency
comment on three years of purity threads, summarised so you do not have to read them in c/hplc · 24 points · 1 year ago
The related substances profile is way more interesting than the main peak %. A 98% with 11 peaks is different from a 98% that is one 13% impurity.
comment on week 31 check-in — 22kg down, muscle cramps manageable, one thing confusing me in c/sideeffects · 8 points · 1 year ago
Same experience. Week 46 and it simply stopped. I know that is not useful information but it is what happened.
comment on [Discussion] chromatogram is doing more work than we give it credit for in c/hplc · 779 points · 1 year ago
related substances are where the story lives, not the main peak

the food-noise thing stops around week 5 for most people

Strongly agree. Largest single impurity tells a different story than total purity.
comment on am I the only one who found tapering harder than the injections in c/tapering · 173 points · 1 year ago
comment on three years of heart rate threads, summarised so you do not have to read them in c/sideeffects · 212 points · 1 year ago
Is that before or after you stabilized your sulphur burps?
Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.
comment on [Results] 27 weeks, 36kg, and private prescription was the hard part in c/glp1uk · 11 points · 1 year ago
Yeah, the NHS waitlist is genuinely two years in most places.
comment on anyone else notice lean mass kicking in around week 24 in c/glp1muscle · 13 points · 1 year ago
Strongly agree. Resistance training counts.
comment on nausea — my 9-week log, condensed into one table in c/sideeffects · 75 points · 1 year ago
