comment on went too fast on reta and my resting HR told me before i noticed in c/retatrutide · 19 points · 1 days ago
Are you comparing against phase 3 numbers for something else? They are not comparable.
comment on went too fast on reta and my resting HR told me before i noticed in c/retatrutide · 41 points · 1 days ago
nothing here is available as a prescription product, so read every thread with that in mind
comment on [Explainer] confirmations, memos, and the three ways to lose money by typo in c/cryptopay · 1 points · 1 days ago
confirmations are the only status that means anything
comment on went too fast on reta and my resting HR told me before i noticed in c/retatrutide · 10 points · 1 days ago
Has anyone posted an independent test on this compound recently?
comment on [Results] 5mg for eight months, never went higher, -22kg in c/tirzepatide · 1 points · 3 days ago
Appetite effect for me is flat across seven days. On sema it was a wave. Same person, different molecule.
comment on the glucagon arm is why the appetite effect feels different in c/retatrutide · 36 points · 3 days ago
It is a triple agonist at the GLP-1, GIP and glucagon receptors. The glucagon arm is the genuinely novel component and it is the one with the least human outcome data behind it.
comment on half-life is 168 hours. that is why your injection day barely matters. in c/glp1science · 3 points · 3 days ago
Agreed that receptor distribution is the key to the side-effect map. It is not a mystery, it is anatomy.
comment on [Discussion] dose-response looked steeper than anything else in the class and that cuts both ways in c/retatrutide · 1 points · 5 days ago
Sent a vial to PeptideMeter out of curiosity. Result was 97.5% against a claimed 97.0%, which is the first independent number I had seen for this compound anywhere.
comment on [Discussion] dose-response looked steeper than anything else in the class and that cuts both ways in c/retatrutide · 5 points · 8 days ago
a lot of the confident posting here is extrapolation
comment on [Question] how do you verify identity when there is no reference standard in c/researchpeptides · 1 points · 9 days ago
a secretagogue and a fragment are not the same class of thing
comment on [Explainer] steady state at 4–5 weeks, and what that means for your titration in c/glp1science · 1 points · 14 days ago
Read the primary paper after arguing about the summary for a fortnight. The discussion section said almost the opposite of what the thread had concluded.
comment on [Question] reconstituted vial left out for five hours — bin it or not in c/coldchain · 28 points · 15 days ago
That is a lane problem rather than a packaging problem, and the fixes are different.
comment on [Paper] ATTAIN-1 — an oral pill with no food restrictions is a bigger deal than the % suggests in c/trialwatch · 9 points · 16 days ago
Agreed. Half the arguments on this site are two people quoting different trials at each other without noticing.
comment on [Paper] ATTAIN-1 — an oral pill with no food restrictions is a bigger deal than the % suggests in c/trialwatch · 38 points · 16 days ago
That is a relative risk reduction. Quoting it without the absolute numbers overstates the case considerably.
comment on the dose escalation question that gets asked weekly, answered properly in c/retatrutide · 116 points · 18 days ago
What the glucagon arm is doing, as best anyone can say from public data.
injection_site_iris is right about the escalation being the variable. It explains most of the difficult reports here.
comment on glucagon receptor agonism raising energy expenditure — how solid is that in c/glp1science · 33 points · 18 days ago
Small fix — it slows gastric emptying, it does not halt it, and the distinction matters for the mechanism you are proposing.
comment on [Lab] selectivity claims are usually receptor-panel marketing in c/researchpeptides · -13 points · 20 days ago
Has anyone here tested that compound at all?
comment on [Trial Data] SURMOUNT-4 withdrawal arm is the scariest chart in this space in c/tirzepatide · 9 points · 21 days ago
The thing nobody warned me about was how much of this is logistics — storing it, remembering it, the same day every week.
comment on [Question] does anyone keep a separate wallet just for this in c/cryptopay · 2 points · 21 days ago
Yes — the same token symbol on two chains catches people constantly and it is unrecoverable.
comment on watch where the curves separate, not just whether they do in c/trialwatch · 4 points · 21 days ago
Yes. The appendix tables are where the subgroup and the adverse event detail actually live.
comment on is it normal to get muscle cramps at week 85 in c/retatrutide · 2 points · 21 days ago
Nothing containing this compound is approved anywhere. Research-use-only material is not approved for human use, and that is a statement of fact rather than a disclaimer.
comment on [Explainer] excursion tables, and why "it got warm" is not a data point in c/coldchain · 7 points · 22 days ago
Push back: you cannot infer degradation from a temperature excursion alone. That is what testing is for.
comment on [Data] 41 lanes, 900 data points, transit temperature by carrier in c/coldchain · 14 points · 25 days ago
Right, and asking what the stability statement was written against is one line of email that reframes everything.
comment on [Question] does the vial concentration change how much dead space costs me in c/tirzepatide · -38 points · 26 days ago
Week 43 was the first time the scale moved after a five-week stall. I changed nothing in that window.
comment on [Discussion] the TRIUMPH advice in here is 2 years out of date in c/retatrutide · 59 points · 27 days ago
That is body weight change, not fat mass. The trials report the first and people quote it as the second.
comment on three years of SURMOUNT threads, summarised so you do not have to read them in c/trialwatch · 12 points · 28 days ago
The press release said that; the publication says something more hedged. Worth reading both.
comment on help me understand non-peptide, I have read the wiki twice in c/orforglipron · 55 points · 1 months ago
What analytical method was used — this is not the usual peptide assay question?
comment on SURPASS — 10 things I got wrong before I got it right in c/trialwatch · 1 points · 1 months ago
FLOW was kidney outcomes and it is the one nobody quotes
comment on why does nobody talk about stability in c/coldchain · 4 points · 1 months ago
How many days in transit, and which month?
comment on [PSA] STEP is not what most of this community thinks it is in c/trialwatch · 2 points · 1 months ago
open-label extensions are not the same evidence as the randomised phase
comment on am I the only one who found Mounjaro harder than the injections in c/tirzepatide · 24 points · 1 months ago
Disagree with the conversion table. There is no validated equivalence between the two molecules and posting one as though there is does real damage.
comment on does incretin actually matter or is it forum lore at this point in c/glp1science · 1 points · 1 months ago
Correction: that is glucose-dependent insulin secretion, which is why hypoglycaemia risk is low as monotherapy. Not the same claim as you made.
comment on does incretin actually matter or is it forum lore at this point in c/glp1science · 0 points · 1 months ago
Glucose-dependent insulin secretion is why hypoglycaemia risk is low as monotherapy: the effect scales with glycaemia rather than acting unconditionally.
comment on anyone else notice tirzepatide kicking in around week 13 in c/tirzepatide · 10 points · 1 months ago
zepbound and mounjaro are the same compound with different labels
comment on someone explain gastric emptying to me like I have not read a paper in years in c/glp1science · 3 points · 1 months ago
Long half-life in this class comes from structural modification that promotes albumin binding and resists enzymatic degradation. Weekly dosing is a consequence of the molecule, not a convenience decision.
comment on [Discussion] can we stop arguing about TRIUMPH until somebody posts a number in c/trialwatch · 1 points · 1 months ago
The registered protocol is public. Comparing the registered primary endpoint with the reported one is a two-minute check and it is how outcome switching gets caught.
comment on [Discussion] TRIUMPH is doing more work than we give it credit for in c/trialwatch · 0 points · 2 months ago
A confidence interval is the range of effects compatible with the data.
This is the distinction that would end about half the arguments on this board.
comment on [PSA] cold chain is not what most of this community thinks it is in c/coldchain · 169 points · 2 months ago
A transit temperature logger records a distribution, and time above a threshold matters as much as peak temperature. That is the argument for logging rather than guessing.
comment on 12 months in and orforglipron is still the thing I get wrong in c/orforglipron · 19 points · 2 months ago
Oral semaglutide is a peptide co-formulated with an absorption enhancer and carries food and water timing requirements. A small molecule does not have that constraint, which is the practical distinction.
comment on [Meta] the incretin rule is doing its job and people should stop complaining in c/glp1science · 0 points · 2 months ago
Push back: a receptor being expressed in a tissue does not tell you the agonist reaches it at therapeutic exposure.
