comment on [Explainer] delayed gastric emptying does most of the work people credit to the brain in c/glp1science · 1 points · 2 days ago

Yeah, the incretin mechanism is doing the work here.

comment on [Trial Data] REDEFINE 1 — what cagri adds on top of sema in c/cagrilintide · 9 points · 2 days ago

not approved anywhere, keep posts descriptive, not instructional

comment on [Explainer] why "compounded" does not mean "generic" in c/compounding · 13 points · 4 days ago

This is correct. The shortage list does expire and the rules change.

comment on [Regulatory] state board actions worth reading if you use a compounder in c/compounding · 2 points · 6 days ago

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

comment on why does GIP agonism seem to reduce nausea rather than add to it in c/glp1science · 14 points · 8 days ago

gastric emptying is real and explains most early early fullness

comment on my compounded vial arrived at a different concentration than last month in c/compounding · 1 points · 8 days ago

Are we talking 503A or 503B?

comment on water content is on the COA and everyone skips it in c/coa · 0 points · 9 days ago

axis labels included, always

comment on glucagon receptor agonism raising energy expenditure — how solid is that in c/glp1science · 68 points · 20 days ago

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

comment on [Question] vendor COA says 99.2%, my Janoshik came back 97.4%. who is wrong in c/coa · -36 points · 20 days ago

genuinely useful, thanks

comment on reading API source threads from 2024 and half of it aged badly in c/compounding · 46 points · 29 days ago

Slight fix: the number was 93.7, not 99.3. Decimal point, but a fairly consequential one.

comment on [COA] full document, nothing cropped, tell me what i am missing in c/coa · 1 points · 1 months ago

Yeah, 96.8% area is not the problem, the missing impurity breakdown is the problem.

permalink

comment on identity and quantity are two questions and most COAs answer one in c/coa · 12 points · 1 months ago

area% is not mass%, and here is exactly why it matters

permalink

comment on anyone else notice water content kicking in around week 50 in c/coa · 270 points · 1 months ago

Half-life is about 168 hours, so steady state lands around week 18–5. Practical consequence: what you feel in week 1 is not what that dose does.

comment on reading area percent threads from 2024 and half of it aged badly in c/coa · 231 points · 2 months ago

This is the correct framing. The COA structure matters as much as the number.

permalink

comment on tried CagriSema for 2 weeks. here is what happened. in c/cagrilintide · 17 points · 2 months ago

Not convinced. The evidence does not support that reading.

comment on [Results] 31 weeks on 5mg, full numbers, ask me anything boring in c/compounding · 33 points · 2 months ago

Did they tell you their API source or dodge the question?

permalink

comment on small win: compounding stopped being a problem at week 40 in c/compounding · 42 points · 3 months ago

controversial sort brought me here and it was worth it

permalink

comment on [Meta] proposal — a flair for certificate of analysis posts in c/coa · 10 points · 3 months ago

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

permalink

comment on [Meta] proposal — a flair for gastric emptying posts in c/glp1science · 4 points · 3 months ago

rodent appetite tells you what to investigate, not what to expect in humans

Disagree on that part. 95.1% and 97.6% on the same vial is normal.

permalink

comment on COA: what the trials say vs what this community says in c/coa · 193 points · 4 months ago

Half-life is about 168 hours, so steady state lands around week 13–5. Practical consequence: what you feel in week 1 is not what that dose does.
