reading triple agonist threads from 2024 and half of it aged badly

Discussion Long Haul ×6 Well Actually ×1 Receipts ×1

Something I keep coming back to: reading triple agonist threads from 2024 and half of it aged badly.

The phase 2 readout ran to 48 weeks in a few hundred participants with a slow escalation. Both the size and the duration matter when people quote the headline number.

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.

Phase 2 estimates effect and finds a dose range. Phase 3 estimates it precisely in a bigger population and catches what phase 2 was too small to see. Treating them as the same tier of evidence is the recurring error here.

If somebody has the same thing measured a different way, post it next to mine and we will see whether they agree.

Increases in heart rate have been reported across this receptor class. The magnitude and clinical significance are exactly what phase 3 is powered to establish.

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.

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

the energy-expenditure story is mechanistically interesting and clinically unproven

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

a lot of the confident posting here is extrapolation

Standing reminder in every thread here: unapproved compound, research material is not for human use, nothing on this board is medical advice.

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

u/emil_wojcik197 points·2 years ago

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.

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.

u/viktor_laurent92 points·2 years ago

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

u/renzo_yildiz50 points·2 years ago

Cosigning the escalation point. Almost every difficult report on this board is from somebody who went up quickly.

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

triple agonist — GLP-1, GIP and glucagon, and the glucagon arm is the new part

replysharereportpermalink
u/source_or_silenceOP27 points·2 years ago

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

u/clara_weiss12 points·2 years ago

This. The phase 2 result was genuinely large and it was also 48 weeks in a few hundred people.

replysharereportpermalink
u/two_mil_or_one8 points·2 years ago

Correction: TRIUMPH is the phase 3 programme. The number you are quoting is from the phase 2 readout, which is a different trial.

replysharereportpermalink
u/lurker_for_years9 points·2 years ago

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

replysharereportpermalink
u/yannick_barros4 points·2 years ago

Yes — the glucagon arm is what makes it a different proposition rather than a stronger version of the others.

replysharereportpermalink
u/reta_and_regret36 points·2 years ago·edited

How fast was the escalation? That is usually the variable that explains the reports.

replysharereportpermalink
u/farid_molnar25 points·2 years ago·edited

Not convinced. You are attributing a week of fatigue to the glucagon arm when the escalation rate alone would explain it.

replysharereportpermalink
u/matias_falk12 points·2 years ago

Agreed, and the framing that helps is: this is a phase 2 compound with phase 3 running. Everything else is inference.

u/trialwatch_theotrial nerd6 points·2 years ago

Agreed, and the framing that helps is: this is a phase 2 compound with phase 3 running.

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

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

u/nikhil_asante2 points·2 years ago·edited

Small fix — three receptors, not two. GLP-1, GIP and glucagon, and the third one is the reason this compound gets its own board.

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.
