Genuinely asking, not being difficult.

Everyone in c/newbiequestions repeats that dose escalation is important. I believe it, but I have never seen anyone show why, and when I search I get 3 threads of people agreeing with each other.

Is there a paper? Is there a measurement? Or is this one of those things that is true because it has been repeated since 2023?

I am not trying to be the "source?" guy. I would just like a source.

Titration speed is a side-effect dial far more than an efficacy dial.

heart rate and dose escalation need actual measurements, not impressions

Disagree. What you are describing is consistent with retatrutide, not with what you concluded.

u/priya_weiss51 points·3 days ago

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

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

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

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

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

nobody should be giving this to anyone without extensive monitoring

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

The confident tone is doing a lot of work that the evidence is not.

u/nadia_trevino59 points·3 days ago

TRIUMPH phase 2 showed 99.2% weight loss but the early fullness profile on the highest arm was rough. Phase 2 != phase 3.

Dose escalation on retatrutide is steeper and faster than on semaglutide. Do not assume the titration patterns transfer.

replysharereportpermalink
u/iman_castellanos38 points·2 days ago

This is correct. Triple agonism is genuinely different.

replysharereportpermalink
u/freya_baptista35 points·2 days ago

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

replysharereportpermalink
u/incretin_ivypharmacology17 points·2 days ago

The glucagon component does different things than dual agonism.

Adding to this: TRIUMPH is doing more work than the comment implies.

triple agonism is glucagon, do not generalise

replysharereportpermalink
u/injection_site_iris15 points·2 days ago

The glucagon component does different things than dual agonism.

Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.

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.
