c/retatrutide·posted 13 days ago by u/cormac_roos

came off reta after 14 weeks. here is the honest version.

Trial Data Clean Column ×3 The Quiet One ×2

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

Everything else people worry about in c/glp1women is downstream of it. Titration speed, early fullness, 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 22 months. My A1c 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.

This is correct. Triple agonism is genuinely different.

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

u/aa_analysis_andy283 points·12 days ago

Small correction: the trial was 15 weeks, not 5. Does not change your point but people will quote it.

What was the dosing schedule in that arm?

u/kofi_balogun82 points·12 days ago

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

nobody should be giving this to anyone without extensive monitoring

Water content matters more than people think. If a vial is carrying residual moisture, your "10mg" is not 10mg of peptide.

the glucagon component changes the side effect profile, not just the efficacy

u/sena_teixeira96 points·13 days ago

Inter-lab variance on this kind of assay is routinely 1–2 points. Different column, different gradient, different integration.

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

Crossposting this to c/sideeffects because the people who need it are not reading this community.

heart rate and dose escalation need actual measurements, not impressions

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

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

u/anya_moreau31 points·11 days ago

Did you actually measure heart rate or is that a feeling?

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

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

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

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.

Before you read on

Several compounds discussed on GLP Research Hub are sold for research use only and are not approved for human use anywhere. Nothing here is medical advice and none of it is written by your clinician. If a post reads like an instruction, treat it as a description of what one stranger did.
