week 32 check-in — 14kg down, nausea manageable, one thing confusing me

Results Clean Column ×7

week 32 check-in — 14kg down, nausea manageable, one thing confusing me, and the part I actually want to talk about is at the bottom.

Numbers, in the order they matter: week 32 and 14kg.

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.

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

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.

u/cagrilintide_enthusiast93 points·9 months ago

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/hassan_nilsen25 points·9 months ago

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

u/careful_gradient_notesOP-22 points·9 months ago

Has anyone posted an independent test on this compound recently?

u/careful_gradient_notesOP1 point·9 months ago

Are you tracking heart rate at all?

u/baseline_drifteranalytical110 points·9 months ago

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

u/nikhil_lindqvist59 points·9 months 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/farid_molnar60 points·9 months ago

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

replysharereportpermalink
u/careful_gradient3218 points·9 months ago

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

u/solene_ilunga53 points·9 months ago

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

replysharereportpermalink
u/cormac_roos30 points·9 months 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.

replysharereportpermalink
u/nadia_norgaard21 points·9 months 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/rohan_cardoso32 points·9 months ago

small trial, big effect, wide error bars

replysharereportpermalink
u/careful_gradient3239 points·9 months ago

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.

replysharereportpermalink
u/devils_advocate_d29 points·9 months 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/rui_only_ro10 points·9 months ago

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

u/incretin_ivypharmacology42 points·9 months ago

a lot of the confident posting here is extrapolation

Sent a vial to Janoshik out of curiosity. Result was 98.9% against a claimed 98.5%, which is the first independent number I had seen for this compound anywhere.

replysharereportpermalink
u/lurker_for_years18 points·9 months ago

the escalation is where most of the reported trouble sits

replysharereportpermalink
u/bastian_ekstrom5 points·9 months ago

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

replysharereportpermalink
u/nikhil_asante16 points·9 months ago

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.

replysharereportpermalink
u/zeynep_mbeki13 points·9 months 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/janek_ferrari9 points·9 months ago

That reads as a titration plan for an unapproved compound. This board cannot host that and it should not want to.

replysharereportpermalink
u/yannick_barros4 points·9 months ago

the energy-expenditure story is mechanistically interesting and clinically unproven

replysharereportpermalink
u/ismael_eriksen5 points·9 months ago

wait for phase 3 before you argue about rankings

replysharereportpermalink
u/hugo_pires13 points·9 months 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/endotoxin_elliemicro4 points·9 months ago

the glucagon component is why the metabolic story reads differently

replysharereportpermalink
u/aa_analysis_andy2 points·9 months ago

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

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.

c/retatrutide rules
  1. Retatrutide is not approved anywhere for human use. Posts must not read as usage instructions.
  2. Phase 2 numbers are not maintenance numbers. Cite the trial and the dose arm.
  3. Heart-rate and dose-escalation reports need actual measurements, not impressions.
  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.
  8. No contact handles, wallet addresses or tracking numbers — they identify people.
  9. Be recognisably decent. Disagree hard, insult nobody.
