comment on [Results] 4 weeks on 15mg, full numbers, ask me anything boring in c/retatrutide · 702 points · 1 year ago
Agreed, and the framing that helps is: this is a phase 2 compound with phase 3 running. Everything else is inference.

label the vial with the date as well as the concentration
comment on does method development actually matter or is it forum lore at this point in c/hplc · 103 points · 1 year ago
Agreed. Two analysts, one trace, two integration choices, and a spread that has nothing to do with the vial.
comment on tried triple agonist for 19 weeks. here is what happened. in c/retatrutide · 29 points · 1 year ago
The food noise profile felt different rather than worse. Hard to describe and impossible to quantify, so take it as an impression.
comment on [Results] 24 weeks on 12.5mg, full numbers, ask me anything boring in c/glp1women · 9 points · 1 year ago
Agreed — logging the cycle alongside everything else is what made my own pattern visible. It was invisible before that.

more water is not more drug, it is the same drug in a bigger volume

Started logging the cycle in the same sheet as the dose. Three months later the pattern was obvious and it had been invisible before.

What the glucagon arm is doing, as best anyone can say from public data.
discount_math_dm is right about the escalation being the variable. It explains most of the difficult reports here.
comment on the bacteriostatic water question that gets asked weekly, answered properly in c/reconstitution · 27 points · 1 year ago
Research-use-only material is not approved for human use, so treat everything in this thread as arithmetic about solutions rather than instructions fo
Disagreeing with this line only: adding more water is not a safety margin, it is a different divisor.

Shook the first vial because nobody told me not to. It was fine, but I have swirled every one since.

phase 2 data only, and people quote it like it is a label

Wrote the date on the vial as well as the concentration after losing track of which one was opened first.

I keep a laminated card in the drawer with the arithmetic on it. Looks ridiculous. Has never once let me draw the wrong volume.

comment on [Meta] the concentration rule is doing its job and people should stop complaining in c/reconstitution · 357 points · 1 year ago
The dead space question sent me down a rabbit hole for a week. It is a fraction of a unit and it is the same every draw.

That is sterile water, not bacteriostatic. Same appearance, different product, and it matters for a multi-draw vial.

What concentration did you actually reconstitute at, rather than what did you intend to?

integration decisions move the number more than the sample does
comment on genuine question about phase 2 that I am slightly embarrassed to ask in c/retatrutide · 190 points · 1 year ago
That is body weight change, not fat mass. The trials report the first and people quote it as the second.
genuine question about phase 2 that I am slightly embarrassed to ask. If this has been answered properly somewhere, link me and I will delete. Read the phase 2 paper…

The same dose genuinely feels different at different points in the month for me. Took a year to notice and it was in the log the whole time.

Correction: that trial did not enrol the population being discussed, so it cannot support the claim.

comment on 3 months in and triple agonist is still the thing I get wrong in c/retatrutide · 89 points · 1 year 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.
comment on someone explain perimenopause to me like I have not read a paper in years in c/glp1women · 87 points · 1 year ago
Has this been raised with whoever prescribes?
Disagreeing with this line: the absorption question has a product-specific answer and a pharmacist has it.
comment on TRIUMPH: what the trials say vs what this community says in c/retatrutide · 20 points · 1 year ago
Are you comparing against phase 3 numbers for something else? They are not comparable.
