week 19 check-in — 9kg down, early fullness manageable, one thing confusing me

Trial Data Clean Column ×1 Well Actually ×3 Slow Clap ×2

week 19 check-in — 9kg down, early fullness manageable, one thing confusing me, logged the same way every week so the comparison is at least internally fair.

The numbers the title promised, since a headline without them is worthless: week 19 and 9kg. Everything below is context for those.

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

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

Research-use-only material is not approved for human use and nothing here should be read as a recommendation to use it.

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

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.

u/priya_weiss549 points·2 years ago

Same read. The energy-expenditure mechanism is the interesting bit and it is not established in humans at scale.

replysharereportpermalink
u/nordic_pricing148 points·2 years ago

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

What is the source for that figure — the published paper or a summary of it?

replysharereportpermalink
u/niels_lindqvist789 points·2 years ago

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

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.

replysharereportpermalink
u/kofi_balogun898 points·2 years ago

Right, and it bears repeating that nothing here is approved anywhere and research material is not for human use.

u/nabila_bakken495 points·2 years ago

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

replysharereportpermalink
u/farid_molnar305 points·2 years ago

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.

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.

replysharereportpermalink
u/lurker_for_years341 points·2 years ago·edited

Nothing containing this compound is approved anywhere.

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

Nothing containing this compound is approved anywhere.

Disagree with this specific inference. A 48-week readout does not tell you the shape of the curve after it.

replysharereportpermalink
u/mateusz_mensah124 points·2 years ago·edited

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

replysharereportpermalink
u/halima_mbeki147 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.

replysharereportpermalink
u/marta_vanhecke420 points·2 years ago

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.

replysharereportpermalink
u/injection_site_iris100 points·2 years ago

Agreed on the heart-rate reports. They are consistent enough across the threads to be worth noting, not enough to be a finding.

replysharereportpermalink
u/lina_bruun309 points·2 years ago

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

replysharereportpermalink
u/zeynep_mbeki192 points·2 years ago

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.

replysharereportpermalink
u/sofia_wikstrom57 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/two_mil_or_one48 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/incretin_ivyOPpharmacology42 points·2 years ago

dose escalation in the trials was slow for a reason

replysharereportpermalink
u/incretin_ivypharmacology29 points·2 years ago

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

replysharereportpermalink
u/yusuf_ramos49 points·2 years ago

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

replysharereportpermalink
u/lina_bruun-7 points·2 years ago

Stopped at a low step because there was no reason to go further and no data to tell me what further would do.

replysharereportpermalink
u/noor_ivaturi162 points·2 years ago

Are you tracking heart rate at all?

u/reflux_report46 points·2 years ago

a lot of the confident posting here is extrapolation

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

small trial, big effect, wide error bars

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.

  4. Independent community. Nobody here sells anything, and anyone who tries is banned.
  5. Not medical advice. Describe what you did; never prescribe to a stranger.
  6. Claims need evidence. Batch numbers, dated screenshots, independent test reports, or a citation.
  7. No referral links, discount codes or affiliate URLs. Permanent ban, no appeal.

Before you read on

Several compounds discussed on GLP Research Hub are sold for research use only and are not approved for human use anywhere. Nothing here is medical advice and none of it is written by your clinician. If a post reads like an instruction, treat it as a description of what one stranger did.
