the COA thing finally clicked for me and I want to write it down
water content. That is the whole post, but I will justify it. Everything else people worry about in c/sideeffects is downstream of it. Titration speed, early fullness,…

comment on [Meta] the mg/mL rule is doing its job and people should stop complaining in c/reconstitution · 16 points · 3 months ago
more water means more units for the same dose, which means finer resolution
comment on [Question] New Zealand — has anyone got a straight answer on certificate of analysis in c/coa · 1 points · 3 months ago
Not to be pedantic but area percent and related substances are being used interchangeably and they are not interchangeable in real life.
Disagree on that part. 98.7% and 98.3% on the same vial is normal.

This is the correct framing. The COA structure matters as much as the number.
comment on COA: what the trials say vs what this community says in c/coa · 310 points · 4 months ago
Cosigning. The batch number is load-bearing information.
comment on genuine question about reconstitution that I am slightly embarrassed to ask in c/reconstitution · 108 points · 4 months ago
Water content matters more than people think. If a vial is carrying residual moisture, your "10mg" is not 10mg of peptide.

Edit to your parent would help — the concentration you quoted assumes one scenario and you have written another above it.

i changed my mind reading this, which never happens

What is the method line say?
Yes, exactly this, and it is the bit that took me 18 weeks to accept.
comment on weekly update — 12 things I got wrong before I got it right in c/dosinglogs · 5 points · 8 months ago
Second this question.
Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.
comment on the Netherlands: area percent, and what it actually costs here in c/coa · -7 points · 8 months ago
Strongly agree. Mass% and area% are answering different questions on the same document.
comment on tracking: the version I wish someone had shown me in week 1 in c/dosinglogs · 4 points · 8 months ago
include dose and date on every update
comment on [Discussion] the related substances advice in here is 9 years out of date in c/coa · 745 points · 9 months ago
no "is this good?" without saying what the compound and claimed purity are
comment on what changed for me between week 45 and week 88 in c/coa · 1.2k points · 9 months ago
Yeah, 96.8% area is not the problem, the missing impurity breakdown is the problem.
comment on Canada: dose history, and what it actually costs here in c/dosinglogs · 1 points · 9 months ago
This is correct.
Adding to this: weekly update is doing more work than the comment implies.
comment on week 81 check-in — 12kg down, injection-site soreness manageable, one thing confusing me in c/coa · -4 points · 11 months ago
the method line is doing real work, not just window dressing
Disagree on that part. 96.2% and 96.8% on the same vial is normal.
comment on why does nobody talk about certificate of analysis in c/coa · 87 points · 11 months ago
purity and net content are two different numbers, same vial
comment on is it normal to get early fullness at week 14 in c/coa · 195 points · 1 year ago
Yeah, 96.8% area is not the problem, the missing impurity breakdown is the problem.
comment on [Vendor] WXT order #18 — the Netherlands, 5 days, no drama, receipts inside in c/reconstitution · 344 points · 1 year ago
four days. it took four days for me.
comment on week 61 check-in — 7kg down, reflux manageable, one thing confusing me in c/reconstitution · 140 points · 1 year ago
Titration speed is a side-effect dial far more than an efficacy dial.
Yes, exactly this, and it is the bit that took me 28 weeks to accept.
