Numbers in the title, numbers in the post. QSC vs Homopeptide on the same compound, same month — both cleared 98.5%. Figures up front so nobody has to dig: 98.5%. Sent…

comment on ferritin — 15 things I got wrong before I got it right in c/bloodwork · -29 points · 1 year ago
Compared two draws across two labs and spent a week worrying before finding out the assays were different.
comment on my ferritin moved and I cannot work out whether FFMI is why in c/glp1muscle · 1 points · 1 year ago
DEXA has a meaningful coefficient of variation, and it differs between machines and protocols. Comparing scans from different clinics adds a systematic offset that is invisible on the report.
comment on am I the only one who found triple agonist harder than the injections in c/retatrutide · 86 points · 1 year ago
Disagree.
blunt_coldbox_2024 is right about the escalation being the variable. It explains most of the difficult reports here.
comment on reading resistance training threads from 2024 and half of it aged badly in c/glp1muscle · 155 points · 1 year ago
the scale cannot distinguish tissue types and never could
comment on the constipation question that gets asked weekly, answered properly in c/sideeffects · -3 points · 1 year ago
The pattern almost everyone here describes, written out once so it can be linked.
A step up is followed by a rough window — commonly reflux arriving the day after the shot and easing by day four, worst in the first fortnight, then flattening out. At a stable dose it usually settles further. Constipation and fatigue tend to track intake and fluid rather than the compound directly, which is why the unglamorous answers work.
What sits outside that pattern: severe pain, symptoms that appear from nowhere weeks into a stable dose, or anything getting worse rather than better over a month. None of that is a board question and none of us can answer it for you.
comment on small win: pentadecapeptide stopped being a problem at week 74 in c/bpc157 · 65 points · 1 year ago
regulatory status varies by jurisdiction and it has moved recently
comment on [Results] 45 weeks on 0.25mg, full numbers, ask me anything boring in c/retatrutide · 180 points · 1 year ago
Small fix — three receptors, not two. GLP-1, GIP and glucagon, and the third one is the reason this compound gets its own board.
comment on gallbladder — 15 things I got wrong before I got it right in c/sideeffects · 579 points · 1 year ago
Disagree. Severe abdominal pain is not on the list of things to wait out, and this board should not be treating it as one.
comment on someone explain LC-MS to me like I have not read a paper in years in c/hplc · 8 points · 1 year ago
What did system suitability look like on that sequence?
comment on TRIUMPH: what the trials say vs what this community says in c/retatrutide · 33 points · 1 year ago
That reads as a titration plan for an unapproved compound. This board cannot host that and it should not want to.
comment on [Results] 57 weeks, 25kg, and glucagon was the hard part in c/retatrutide · 350 points · 1 year ago
Same read. The energy-expenditure mechanism is the interesting bit and it is not established in humans at scale.
comment on [Discussion] can we stop arguing about eGFR until somebody posts a number in c/bloodwork · 47 points · 1 year ago
baseline before you start is worth more than any later panel
comment on stalled for 7 weeks at 10mg and I refuse to panic this time in c/retatrutide · 13 points · 2 years ago
How fast was the escalation? That is usually the variable that explains the reports.
comment on help me understand pentadecapeptide, I have read the wiki twice in c/bpc157 · 17 points · 2 years ago
Reconstituted or powder, and how long has it been in solution?
comment on help me understand pentadecapeptide, I have read the wiki twice in c/bpc157 · 47 points · 2 years ago
Do you have the mass spectrum?
comment on help me understand pentadecapeptide, I have read the wiki twice in c/bpc157 · 81 points · 2 years ago
Has anyone posted an independent result on that batch?
Trying to get a straight answer on this: help me understand pentadecapeptide, I have read the wiki twice. Asked SGN for the theoretical mass alongside the certificate…
comment on nobody warned me about reflux and I would have liked the warning in c/bloodwork · 13 points · 2 years ago
a single A1c outside range is a reason to repeat, not to panic
comment on someone explain phase 2 to me like I have not read a paper in years in c/retatrutide · 1 points · 2 years ago
the TRIUMPH programme is still running, so anything definitive is premature
comment on someone explain phase 2 to me like I have not read a paper in years in c/retatrutide · 41 points · 2 years ago
comparing reta phase 2 to sema phase 3 is comparing different things
comment on [Lab] 16th independent test on ERP — 97.4% on a claimed 97.0%, and the trend is the interesting part in c/hplc · 104 points · 2 years ago
Correction: that is a tailing factor, not a plate count. Different diagnostics for different problems.
comment on integration is the most under-discussed thing on this board in c/hplc · 99 points · 2 years ago
Traces need axes labelled — that is the one hard rule here and it exists because an unlabelled trace cannot be argued about.
Disagreeing with this bit: that spread is ordinary inter-lab variance, not a disagreement about the material.
comment on retatrutide — my 21-week log, condensed into one table in c/retatrutide · 9 points · 2 years ago
heart rate is the thing people report watching
comment on reading tendon threads from 2024 and half of it aged badly in c/bpc157 · 49 points · 2 years ago
Not convinced.
Agreed — and the preclinical to clinical gap is where nearly all the overclaiming happens.
comment on what would you tell week-1 you about dose escalation in c/retatrutide · 113 points · 2 years ago
Independent purity testing on this compound is thin compared with the older molecules, simply because fewer members have paid for it. Fewer results means wider uncertainty, not a verdict.
comment on [Lab] QSC cagri — Janoshik came back 98.6% against a claimed 98.5% in c/hplc · 1 points · 2 years ago
214nm sees the peptide bond, 280nm sees the aromatics
comment on [Lab] QSC cagri — Janoshik came back 98.6% against a claimed 98.5% in c/hplc · -5 points · 2 years ago
Disagree. Inter-lab spread of a point or two on this assay is ordinary and calling it a discrepancy misleads people.
comment on is it normal to get sulphur burps at week 24 in c/retatrutide · 24 points · 2 years ago
Push back: quoting the phase 2 headline as an expected outcome is not a fair reading of a small trial with wide intervals.
comment on [Results] 78 weeks on 12.5mg, full numbers, ask me anything boring in c/bloodwork · 1 points · 2 years ago
Have you taken this to whoever ordered it?
comment on [Discussion] can we stop arguing about HPLC until somebody posts a number in c/hplc · 86 points · 2 years ago
axis labels or the trace is decoration
