stalled for 11 weeks at 12.5mg and I refuse to panic this time

Trial Data Receipts ×1

stalled for 11 weeks at 12.5mg and I refuse to panic this time, and I am aware this is a minority view on this board.

The relevant figures are 11 weeks and 12.5mg, and they come from the same log I have kept the whole time.

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.

That is everything I have. The rest is opinion and I have tried to keep it out.

Removed the escalation schedule. There is no published protocol for members to follow and inventing one here is exactly what this board does not do.

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.

u/marta_vanhecke65 points·1 year 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.

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

a lot of the confident posting here is extrapolation

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

u/yannick_salinas16 points·1 year ago

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

replysharereportpermalink
u/aa_analysis_andy0 points·1 year ago

Not convinced.

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

u/yannick_salinas54 points·1 year ago

The injection-site soreness profile felt different rather than worse. Hard to describe and impossible to quantify, so take it as an impression.

u/lurker_for_years27 points·1 year ago

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

replysharereportpermalink
u/soren_nkemelu8 points·1 year ago

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

u/priya_weiss20 points·1 year 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.

u/rui_only_ro14 points·1 year ago

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

u/lurker_for_yearsOP8 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/aa_analysis_andy5 points·1 year 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/reta_and_regret4 points·1 year 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/matias_falk23 points·1 year ago

Which phase 2 arm are you quoting, and at what week?

replysharereportpermalink
u/kavya_kravchenko14 points·1 year 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/lurker_for_yearsOP9 points·1 year ago

the escalation is where most of the reported trouble sits

u/vito_beaulieu18 points·1 year ago·edited

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

u/naomi_erdogan7 points·1 year ago

the energy-expenditure story is mechanistically interesting and clinically unproven

replysharereportpermalink
u/ferran_krastev2 points·1 year ago

Sent a vial to Medutest out of curiosity. Result was 98.5% against a claimed 98.0%, which is the first independent number I had seen for this compound anywhere.

replysharereportpermalink
u/customs_seizure_sid5 points·1 year ago

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

replysharereportpermalink
u/andres_sorensen25 points·1 year ago

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

heart rate is the thing people report watching

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.
