c/retatrutide·posted 5 months ago by u/careful_gradient32

week 16 check-in — 42kg down, constipation manageable, one thing confusing me

Discussion Slow Clap ×5 Receipts ×1

Been lurking in c/sideeffects for about 17 months and finally have something worth posting.

Short version: week 36, 5mg, and triple agonist is the bit I still cannot get a straight answer on. I have read the wiki, I have read the last 13 threads, and the answers split roughly down the middle.

What I actually want to know is whether the people saying it does not matter have measured it, or whether it is just repeated confidently. Happy to be told I am overthinking this — I probably am — but I would rather overthink it now than at week 42.

The practical rule people converge on is 28 days at fridge temperature after first puncture, and that comes from the preservative, not the peptide.

nobody should be giving this to anyone without extensive monitoring

the 1.7mg arm is different from 2.4mg, results do not transfer

retatrutide is not approved anywhere for human use, posts must not read as instructions

That is net peptide content, not purity. Different number, different meaning.

Research use material only, no human-use approval anywhere. Posts must describe what happened, not instruct strangers.

u/yusuf_ramos114 points·5 months ago

This is correct. Triple agonism is genuinely different.

Removed a chain here. The rule is one line long and it is not negotiable.

Not to be pedantic but triple agonist and glucagon are being used interchangeably and they are not interchangeable in real life.

phase 2 numbers are not maintenance numbers, cite the trial

u/careful_gradient_notes76 points·5 months ago

Yeah, phase 2 retatrutide is interesting but it is not comparable to phase 3 compounds.

The heart rate signal in TRIUMPH is real and concerning. Higher doses had higher mean HR changes.

triple agonism plus glucagon is a different physiological state than GIP/GLP-1 dual

TRIUMPH data is phase 2, not phase 3, smaller n and shorter

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.
