this thread has already been worth more than the last twenty i read

i genuinely did not know water was invisible to the detector. that reframes about half of what i thought i understood.

oh. so the number is not the issue, the missing breakdown is the issue.
comment on two labs, same vial, 98.1 and 96.4. both right? in c/hplc · 71 points · 2 days ago
i have been treating the higher number as the true one this whole time. edit: and specifically i once emailed a vendor about a 1.2 point gap. i would like that email back.
comment on [Janoshik] SSA tirz 10mg — 99.1%, third batch in a row above 99 in c/labresults · 52 points · 2 days ago
i had absolutely made that mistake before reading this
comment on is 96.8% area% actually fine or am i being sold a rounding error in c/coa · 71 points · 2 days ago
doing that. edit: sent to Janoshik, will post in c/labresults either way even if it makes me look silly.
comment on [Explainer] area% is not mass% and here is exactly why it matters to your vial in c/coa · 74 points · 3 days ago
i have been on this site four months and this is the first time the two numbers have made sense. edit: went back and re-read three of my own old posts and i was confusing them in all of them.
comment on [Country Guide] personal import rules, my country, with the actual citations in c/customs · 106 points · 3 days ago
Small correction: the trial was 4 weeks, not 24. Does not change your point but people will quote it.
comment on bought a second-hand HPLC. worst best decision of my life. AMA in c/hplc · 143 points · 3 days ago
genuine question — did it change what you buy, or just how you talk about it?
comment on net peptide content vs purity — two different numbers, same vial, and only one is on your COA in c/coa · 68 points · 5 days ago
so a 10mg vial might have nine milligrams of peptide and everyone involved has been honest. edit: yes, per the table in the other thread. this is the least satisfying accurate answer i have received.
comment on QSC: six tests, 4.7 points of spread, and the best one is as good as anything in the directory in c/labresults · 71 points · 5 days ago
the naming situation in this industry is genuinely hostile to newcomers
comment on [Seizure] third one in two years. the pattern is the carrier, not the country. in c/customs · 1 points · 9 days ago
research-use documentation is not a magic word
comment on [Update] week 30, appetite returning, dose unchanged, weight flat in c/dosinglogs · 2 points · 23 days ago
the 25 week mark is where it gets interesting
comment on 9 months in and jurisdiction is still the thing I get wrong in c/customs · 21 points · 2 months ago
The fatigue was genuinely awful for three weeks and then simply stopped. I know that is not useful information, but it is what happened.
comment on unpopular opinion: seizure is massively overrated in c/customs · 36 points · 2 months ago
customs holds vary by season
comment on three years of weight threads, summarised so you do not have to read them in c/dosinglogs · 12 points · 2 months ago
long-running logs are the value

long-running logs are the value

seizure and reship are different outcomes
