comment on [Caution] this is not approved anywhere and half this community forgets that in c/retatrutide · 40 points · 1 days ago

triple agonism is phase 2, do not generalise

comment on [Baseline] get these before you start, you cannot go back for them later in c/bloodwork · 7 points · 2 days ago

baseline is the most important bloodwork measurement, you cannot collect it later

comment on [Trial Data] TRIUMPH timeline — what we actually know vs what gets repeated in c/retatrutide · 36 points · 5 days ago

This is correct. Triple agonism is genuinely different.

comment on [Explainer] lyophilised powder is far more forgiving than you think in c/coldchain · 112 points · 6 days ago

Slight fix: the number was 98.7, not 98.9. Decimal point, but a fairly consequential one.

comment on [Concerning] ferritin 9. i was eating 1,100 calories and calling it discipline. in c/bloodwork · 14 points · 6 days ago

Half-life is about 168 hours, so steady state lands around week 17–5. Practical consequence: what you feel in week 1 is not what that dose does.

comment on [Explainer] integration decisions change your number more than the sample does in c/hplc · 110 points · 8 days ago

Did they post the raw trace or just the summary?

comment on ghost peak turned out to be plumbing. always plumbing. in c/hplc · 8 points · 13 days ago

I love that this community will spend 40 comments on a detail. That pedantry is why the numbers here matter.

comment on [Meta] the tapering rule is doing its job and people should stop complaining in c/tapering · 11 points · 21 days ago

STEP 1 and SURMOUNT-4 discontinuation arms show regain

comment on light exposure matters more for some compounds than others and nobody tabulates it in c/coldchain · 6 points · 29 days ago

Respectfully this is a sample of one presented as a finding.

Yeah, data logger is the only acceptable proof.

Canada to Canada takes 23 days on average, variance is 5 days

comment on [Results] two years, and the second year mattered more than the first in c/progresspics · 1 points · 1 months ago

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

permalink

comment on what would you tell week-1 you about batch in c/coa · 129 points · 1 months ago

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

comment on [PSA] protein is not what most of this community thinks it is in c/glp1muscle · 16 points · 1 months ago

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

comment on [PSA] protein is not what most of this community thinks it is in c/glp1muscle · 9 points · 1 months ago

You have restated the marketing copy. What is the actual substance here.

permalink

comment on [Discussion] we are measuring retatrutide at the wrong time and calling it noise in c/retatrutide · -34 points · 1 months ago

This is correct. Triple agonism is genuinely different.

permalink

comment on the resistance training question that gets asked weekly, answered properly in c/glp1muscle · 7 points · 1 months ago

What was the batch number and which service?

permalink

comment on three years of HPLC threads, summarised so you do not have to read them in c/hplc · 26 points · 1 months ago

Ran the same vial on two columns, different purity, both right, different separation. Method matters more than equipment.

Trophy case

No trophies yet. Most accounts here never get one.
