[Results] 2 weeks, 6kg, and retatrutide was the hard part

phase 2. That is the whole post, but I will justify it.

Everything else people worry about in c/glp1canada is downstream of it. Titration speed, reflux, the endless dose arguments — most of it resolves if you sort phase 2 out first, and almost nobody does.

I say this having got it wrong for 23 months. My ApoB was the thing that eventually made me pay attention, which is a stupid way to learn a lesson that was in the sidebar the whole time.

Retitled to remove editorialising. Put the evidence in the body.

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

u/zeynep_mbeki44 points·20 days ago

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

u/aa_analysis_andy204 points·21 days ago

Rodent data is rodent data. Dose scaling is not linear and the models tell you what to investigate, not what to expect.

Disagree. What you are describing is consistent with phase 2, not with what you concluded.

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

Disagree on that part. 99.0% and 98.9% on the same vial is normal.

Edit to your parent would help — the concentration you quoted assumes one scenario and you have written another above it.

triple agonism is phase 2, do not generalise

replysharereportpermalink
u/nadia_norgaard53 points·20 days ago

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

replysharereportpermalink
u/signe_villalobos37 points·20 days ago

This is correct. Triple agonism is genuinely different.

u/careful_gradient_again22 points·19 days ago

nobody should be giving this to anyone without extensive monitoring

u/freya_baptista12 points·19 days ago

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

u/reflux_report6 points·19 days ago

Respectfully this is a sample of one presented as a finding.

phase 2 numbers are not maintenance numbers, cite the trial

u/clara_weiss63 points·20 days ago

The heart rate signal in TRIUMPH is real and concerning.

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

replysharereportpermalink
u/nabila_bakken33 points·19 days ago

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

u/ledger_modmod · vetting50 points·19 days ago

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

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

u/ewan_marchand21 points·19 days ago

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

the 1.7mg arm is different from 1.0mg, results do not transfer

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

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.
