comment on help me understand purity, I have read the wiki twice in c/coa · 85 points · 4 months ago

Water content on the document? That affects your concentration math.

comment on small win: batch stopped being a problem at week 6 in c/coa · 12 points · 4 months ago

the counterion is part of the mass you paid for

comment on dose stretching — 7 things I got wrong before I got it right in c/maintenancephase · 99 points · 4 months ago

Strongly agree. Lowest effective dose is a real discovery process.

comment on milestone is the most under-discussed thing in c/bloodwork in c/progresspics · 6 points · 5 months ago

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

text removes the body-shaming pile-on

comment on unpopular opinion: COA is massively overrated in c/coa · 10 points · 5 months ago

That is net peptide content, not purity. Different number, different meaning.

permalink

comment on am I the only one who found baseline labs harder than the injections in c/bloodwork · 4 points · 5 months ago

Yeah, baseline matters more than any later number.

comment on goal weight: the version I wish someone had shown me in week 1 in c/maintenancephase · 32 points · 6 months ago

Disagree. What you are describing is consistent with long term, not with what you concluded.

comment on anyone else notice progress kicking in around week 89 in c/progresspics · 7 points · 6 months ago

Not to be pedantic but progress and struggle are being used interchangeably and they are not interchangeable in real life.

comment on stalled for 22 weeks at 1.0mg and I refuse to panic this time in c/coa · 1 points · 6 months ago

Water content was 3.8%, acetate was 6.2%, purity was 99%, but net peptide was only 90% of the label weight.

Disagree on that part. 99.2% and 98.3% on the same vial is normal.

lowest effective dose is maintenance, find it or stay higher

comment on [Question] New Zealand — what am I missing here in c/glp1aus · 5 points · 9 months ago

Ireland here. Waited 20 months on a list, gave up, went private, and the total cost was roughly what I expected.

comment on [Question] New Zealand — what am I missing here in c/glp1aus · 12 points · 9 months ago

Came off after 39 weeks for financial reasons. Regained about a third over the following year. Back on now at a much lower dose.

the 2024 compounding rule change closed a major route overnight

comment on week 56 check-in — 12kg down, injection-site soreness manageable, one thing confusing me in c/coa · 32 points · 9 months ago

purity and net content are two different numbers, same vial

Disagree on that part. 97.4% and 96.2% on the same vial is normal.

permalink

comment on what changed for me between week 45 and week 88 in c/coa · 174 points · 9 months ago

Strongly agree. Mass% and area% are answering different questions on the same document.
