[Lab] WXT reta — PeptideMeter came back 97.7% against a claimed 97.0%

Lab Well Actually ×1 Long Haul ×2 Sourced ×2

Short version of the title, which is already short: WXT reta — PeptideMeter came back 97.7% against a claimed 97.0%. Longer version underneath.

Pulling the figures out of the title: 97.7% and 97.0%. All of it is written down as it happened rather than reconstructed.

Read the phase 2 paper twice before ordering anything. Recommend that to anyone in this board: the error bars are the interesting part.

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.

Not medical advice, obviously, and nothing here is approved for human use. One person with a spreadsheet.

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.

Went up slowly, deliberately, because everything on this board says the escalation is where trouble lives. Uneventful so far and I am not going to pretend that is a finding.

What do you think the glucagon component is adding, specifically?

u/tired_ledger_notes-14 points·1 year ago

Push back: quoting the phase 2 headline as an expected outcome is not a fair reading of a small trial with wide intervals.

u/cold_chromatogram_only1 point·1 year ago

the phase 2 numbers were striking and they were also 48 weeks in a small population

u/freya_baptistaOP1 point·1 year ago

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

u/incretin_ivyMOD164 points·1 year ago

Left up. It reads the phase 2 paper carefully and it is honest about the intervals.

This is the sentence the rest of the board should read first. Phase 2 is not a label.

The muscle cramps profile felt different rather than worse. Hard to describe and impossible to quantify, so take it as an impression.

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

Are you tracking heart rate at all?

u/nordic_pricing76 points·1 year ago

dose escalation in the trials was slow for a reason

u/helga_vermeulen89 points·1 year ago

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

replysharereportpermalink
u/yannick_salinas20 points·1 year ago

not approved anywhere, which is the single most important fact in this board

replysharereportpermalink
u/deleted_my_history29 points·1 year ago

nothing here is available as a prescription product, so read every thread with that in mind

replysharereportpermalink
u/yannick_salinas12 points·1 year ago

Yes — the comparison threads are apples to oranges and they generate more heat than anything else here.

Careful with the rankings. A phase 2 result and a phase 3 result are not on the same evidential footing and cannot be listed in one table.

u/crosspost_bot_no14 points·1 year ago

Sceptical of the extrapolation. Forty-eight weeks does not tell you about seventy-two, and the curve shape is exactly what is unknown.

replysharereportpermalink
u/honest_syringe_202548 points·1 year ago

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

replysharereportpermalink
u/freya_baptistaOP29 points·1 year ago

Correcting my own comment above: that figure was the 36-week interim, not the 48-week endpoint.

u/tired_ledger_notes37 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.

replysharereportpermalink
u/bastian_ekstrom39 points·1 year ago

the glucagon component is why the metabolic story reads differently

About c/retatrutide

Retatrutide: GIP/GLP-1/glucagon triple agonism, the TRIUMPH programme, and the fact that most people discussing it are handling research-grade material with no human-use approval anywhere. Dose-response, heart-rate signal, and the unusually steep phase-2 weight curves get argued about here weekly.
