went too fast on reta and my resting HR told me before i noticed

Lab Cold Box ×6 Sourced ×1

went too fast on reta and my resting HR told me before i noticed. Change my mind, genuinely — I have no stake in being right about this.

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

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

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

Corrections welcome, especially the pedantic ones. Pedantry is how this board earns its reputation.

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.

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

u/lina_bruun159 points·1 days 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.

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

a lot of the confident posting here is extrapolation

u/bastian_ekstrom19 points·1 days ago

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

u/nadia_norgaard9 points·1 days ago

the escalation is where most of the reported trouble sits

replysharereportpermalink
u/ledger_modMOD83 points·1 days ago

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.

replysharereportpermalink
u/bastian_ekstromOP41 points·1 days ago

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

u/nabila_bakken14 points·1 days ago

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

u/incretin_ivypharmacology58 points·2 days 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/vito_beaulieu29 points·2 days ago

the phase 2 numbers were striking and they were also 48 weeks in a small population

replysharereportpermalink
u/rosa_almeida23 points·2 days 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/honest_syringe_20258 points·1 days ago

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

replysharereportpermalink
u/baseline_drifteranalytical47 points·1 days ago

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

replysharereportpermalink
u/viktor_laurent58 points·1 days ago

Not convinced.

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

u/clara_weiss40 points·19 hr ago

Sent a vial to PeptideMeter out of curiosity. Result was 97.7% against a claimed 97.5%, which is the first independent number I had seen for this compound anywhere.

u/soren_nkemelu42 points·20 hr ago

baseline_drifter is right about the escalation being the variable.

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

u/cagrilintide_enthusiast32 points·8 hr ago

Disagree with this specific inference.

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

replysharereportpermalink
u/freya_baptista24 points·2 days ago

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

replysharereportpermalink
u/reflux_report17 points·2 days ago

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

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

u/careful_gradient3220 points·2 days ago

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

u/marta_vanhecke16 points·2 days ago

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

replysharereportpermalink
u/yannick_salinas16 points·2 days ago

Is that the 48-week figure or an earlier readout?

replysharereportpermalink
u/bastian_ekstromOP10 points·1 days ago

Has anyone posted an independent test on this compound recently?

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.

  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.
