c/retatrutide·posted 1 year ago by u/yannick_barros

my A1c moved and I cannot work out whether phase 2 is why

Trial Data Cold Box ×7 Long Haul ×2

Long-ish post, sorry. tl;dr at the bottom.

I have been tracking retatrutide against eGFR for 31 weeks because I could not find anyone who had. The correlation is weaker than I expected, which is itself mildly interesting given how confidently people link the two in here.

Caveats up front: one person, one lab, one assay, no control, and I changed my training in the middle of it, which was stupid.

tl;dr: probably real, definitely smaller than the threads imply, and not worth reorganising your week around.

I love that this community will spend 40 comments on a detail. That pedantry is why the numbers here matter.

Strongly agree. Heart rate escalation needs the actual data, not impressions.

phase 2 numbers are not maintenance numbers, cite the trial

triple agonism is phase 2, do not generalise

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

Sceptical. If this were true we would see it reflected in the data and we do not.

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

u/nikhil_asante94 points·1 year ago

This is correct. Triple agonism is genuinely different.

The glucagon component does different things than dual agonism. The nausea are not just amplified versions.

the dosing is steep, the sulphur burps reports are real, and nobody knows the human safety yet

the 7.5mg arm is different from 5mg, results do not transfer

u/freya_baptista1 point·1 year ago

the weight curves are unusually steep, which makes predicting individual response harder

nobody should be giving this to anyone without extensive monitoring

triple agonism is glucagon, do not generalise

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

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.
