comment on went too fast on reta and my resting HR told me before i noticed in c/retatrutide · 40 points · 19 hr ago

Sent a vial to PeptideMeter out of curiosity. Result was 97.7% against a claimed 97.5%, which is the first independent number I had seen for this compound anywhere.

comment on [PSA] your bac water is fine, your fridge door is not in c/reconstitution · 8 points · 1 days ago

Agreed on the swirl. There is no reason to shake it and a good reason not to.

comment on reta phase 2 was -24.2% at 48 weeks and people quote it like it is a maintenance number in c/retatrutide · 58 points · 1 days ago

Disagree. "More receptors means more effect" is not how any of this works and the trial data does not support the linear story.

comment on reta phase 2 was -24.2% at 48 weeks and people quote it like it is a maintenance number in c/retatrutide · 37 points · 1 days ago

That is body weight change, not fat mass. The trials report the first and people quote it as the second.

comment on [PSA] your bac water is fine, your fridge door is not in c/reconstitution · 46 points · 2 days ago

If your calculation produces a fraction of a unit, the concentration is wrong for your dose. Change the water volume until the numbers land on whole units.

comment on foam means you shook it. do not shake it in c/reconstitution · -6 points · 3 days ago

Not quite. Bacteriostatic and sterile water are not interchangeable for a multi-draw vial, and the difference is the preservative.

comment on [Question] small molecule means purity testing is a different problem, right in c/orforglipron · 31 points · 4 days ago

Compared milligram figures across two completely different molecule classes in a comment. Deserved the correction.

comment on [Caution] CagriSema trial ratios are fixed-dose, do not extrapolate to self-mixing in c/cagrilintide · 7 points · 4 days ago

phase 3 data will change most of what gets said here

comment on [Management] the only three things that helped my constipation, ranked in c/sideeffects · 5 points · 4 days ago

Are you eating in the couple of hours before you sleep?

permalink

comment on i stopped eating at 70% full and the vomiting stopped entirely in c/sideeffects · 1 points · 4 days ago

A symptom that begins the day after the shot and fades by day four tracks the exposure curve. One that appears at random in week 51 probably does not, and that is worth saying to a clinician rather than to us.

permalink

comment on hair started shedding at month 4 and stopped at month 9, protein and patience in c/sideeffects · 0 points · 7 days ago

The fatigue turned out to be that I was eating about a third of what I thought I was.

Agreed, with the caveat that "usually settles" is not "always settles" and the exceptions should still get asked about properly.

permalink

comment on [TGA] shortage notice archive, worth bookmarking in c/glp1aus · 16 points · 8 days ago

Disagree — that is registration status, and the question was about subsidy. Different decisions, different bodies.

permalink

comment on [Question] why is reta purity testing so much more variable between labs in c/retatrutide · 10 points · 10 days ago

Kept a log specifically because there is so little published. It is one person and it is not data.

permalink

comment on Denmark: compounding, and what it actually costs here in c/glp1aus · 5 points · 14 days ago

Careful, personal importation provisions are narrow and specific and the general version circulating here is wrong.

permalink

comment on [Trial Data] nausea rates in the combination arm vs sema alone in c/cagrilintide · 6 points · 17 days ago

satiety signalling rather than incretin signalling

permalink

comment on my gallbladder came out at month 7 and i would still do it again in c/sideeffects · 22 points · 22 days ago

hair shedding follows the weight loss, not the drug, and it stops

permalink

comment on [Question] is 97.6% actually fine or am I being sold a rounding error in c/cagrilintide · 10 points · 26 days ago

Is there any independent purity data on this compound that you have seen?

comment on genuine question about mg/mL that I am slightly embarrassed to ask in c/reconstitution · 23 points · 1 months ago

Adding more water does not change how much peptide is in the vial. It changes the concentration, which changes the volume you draw for the same amount. That is the entire relationship.

permalink

comment on genuine question about mg/mL that I am slightly embarrassed to ask in c/reconstitution · 108 points · 1 months ago

reconstituting at a round concentration makes every later dose easy

permalink

comment on help me understand mg/mL, I have read the wiki twice in c/reconstitution · 65 points · 1 months ago

The lyophilised cake displaces a small volume, so the true concentration is very slightly lower than the arithmetic suggests. It is a fraction of a percent and it is dwarfed by fill tolerance.

comment on amylin — 23 things I got wrong before I got it right in c/cagrilintide · 25 points · 1 months ago

Correcting myself upthread: I gave the 72-week figure and the paper reports 26 weeks.

permalink

comment on retatrutide is the most under-discussed thing on this board in c/retatrutide · 58 points · 1 months ago

Watched heart rate on a wearable across twelve weeks because the threads said to. It moved a little and I have no idea whether that means anything.

permalink

comment on amylin — 23 things I got wrong before I got it right in c/cagrilintide · 8 points · 1 months ago

Which trial and which readout?

permalink

comment on amylin — 23 things I got wrong before I got it right in c/cagrilintide · 14 points · 1 months ago

Which receptor family are you attributing that effect to?

comment on small win: dose escalation stopped being a problem at week 55 in c/retatrutide · 3 points · 1 months ago

small trial, big effect, wide error bars

permalink

comment on [Below Spec] 94.1% with a 1.8% single impurity. is that the des-amido in c/labresults · 2 points · 1 months ago

area percent unless the report says otherwise

comment on someone explain concentration to me like I have not read a paper in years in c/reconstitution · 43 points · 1 months ago

units are a volume on a U-100 syringe, not a dose

permalink

comment on someone explain CagriSema to me like I have not read a paper in years in c/cagrilintide · 24 points · 1 months ago

Agreed that the monotherapy numbers look modest out of context and that the context is the whole story.

this is a less-travelled board and the evidence base shows it

comment on unpopular opinion: most of what gets said here about triple agonist is guesswork in c/retatrutide · 1 points · 1 months ago

The thing that surprised me was how much of the discussion here is inference rather than measurement.

permalink

comment on unpopular opinion: most of what gets said here about triple agonist is guesswork in c/retatrutide · 60 points · 1 months ago

Removed the escalation schedule.

Adding the standing caveat: none of this is approved anywhere and research material is not for human use.

permalink

comment on unpopular opinion: most of what gets said here about triple agonist is guesswork in c/retatrutide · -22 points · 1 months ago

Independent purity testing on this compound is thin compared with the older molecules, simply because fewer members have paid for it.

Agreed, and the glucagon arm is exactly why the comparison threads do not work.

permalink

comment on [Discussion] the bacteriostatic water advice in here is 3 years out of date in c/reconstitution · 73 points · 1 months ago

Show the arithmetic — where did the unit figure come from?

permalink

comment on anyone else notice glucagon kicking in around week 51 in c/retatrutide · 7 points · 2 months ago

comparing reta phase 2 to sema phase 3 is comparing different things

permalink

comment on is it normal to get injection-site soreness at week 72 in c/retatrutide · 22 points · 2 months ago

It is a triple agonist at the GLP-1, GIP and glucagon receptors.

incretin_ivy is right about the escalation being the variable. It explains most of the difficult reports here.

permalink

comment on my ApoB moved and I cannot work out whether constipation is why in c/sideeffects · 15 points · 2 months ago

The fatigue turned out to be that I was eating about a third of what I thought I was. Tracked it for a week and the mystery evaporated.

comment on unpopular opinion: most of what gets said here about insulin syringe is guesswork in c/reconstitution · -13 points · 2 months ago

if the maths gives you a fraction of a unit, change the concentration

permalink

comment on dose escalation is the most under-discussed thing on this board in c/retatrutide · 6 points · 2 months ago

Is that the 48-week figure or an earlier readout?

permalink

comment on triple agonist: what the trials say vs what this community says in c/retatrutide · 70 points · 3 months ago

Are you comparing against phase 3 numbers for something else? They are not comparable.
