stalled for 7 weeks at 10mg and I refuse to panic this time

Trial Data Well Actually ×5 Cold Box ×3

Thinking out loud about this: stalled for 7 weeks at 10mg and I refuse to panic this time.

7 weeks and 10mg — those are the numbers, and they are the ones I am willing to defend.

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.

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.

Sceptical readings welcome. The confident ones are the ones I distrust.

Glucagon receptor agonism is associated with increased energy expenditure and with hepatic effects. That is a mechanistic story with strong preclinical support and limited phase 2 human data.

heart rate is the thing people report watching

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.

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

Where the evidence actually stands, since every thread here assumes a different answer.

Phase 2 reported a large mean body weight change at 48 weeks across a few hundred participants with a slow, protocol-driven escalation. The effect size was striking. The confidence intervals were wide, the population was small, and the duration was under a year.

Phase 3 is running. Until it reports, everything else — including the ranking arguments this board loves — is extrapolation from a small study. That is not a criticism of the compound; it is a description of the evidence.

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

Same read.

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

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.

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

u/tired_ledger_notes27 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.

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

replysharereportpermalink
u/lurker_for_yearsOP16 points·2 years ago

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

research-use-only material is not approved for human use, full stop

u/heart_rate_bump7 points·2 years 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.

u/reta_and_regretMOD24 points·2 years ago

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

u/ewan_marchand8 points·2 years ago

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

dose escalation in the trials was slow for a reason

replysharereportpermalink
u/arne_amankwah8 points·2 years ago

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

u/ferran_krastev4 points·2 years ago

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

u/naomi_erdogan3 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.

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.
