co-agonism — my 6-week log, condensed into one table

Discussion Clean Column ×6 Well Actually ×2

Posting this because I searched for it and got nothing useful.

Setup: 0.25mg, week 28, constipation present but not ruining anything. I changed exactly one variable — REDEFINE — and tracked it for 21 weeks.

Result: a difference, but a small one, and well inside what I would call noise if someone else posted it. So I am putting it here rather than presenting it as a finding. If two or three other people have done the same thing we might actually learn something.

Not medical advice, obviously. This is one person with a spreadsheet.

Dead space in the needle hub holds a small but non-trivial volume. On low-volume draws that can be several units.

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

This is correct. The co-agonism is real.

Yes, exactly this, and it is the bit that took me 65 weeks to accept.

Yeah, amylin is doing different work than GLP-1.

Rodent or human data?

u/controversial_only131 points·11 months ago

amylin is not a GLP-1, posts conflating them get corrected

Every time this gets posted it hits the front page and every time someone has to re-explain it.

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

The research community is small on cagrilintide. Forum lore changes faster than data.

amylin receptor distribution is different from GLP-1

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

CagriSema is a fixed combo in trials, not user-mixed

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

Flair changed to match the content. Read the sidebar before posting next time and we are square.

u/zaid_grimaldi61 points·11 months 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.

u/iman_castellanos0 points·11 months ago

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

REDEFINE phase 23 readouts are interesting but 23 person cagrilintide is different from 23 trial cagrilintide.

The satiety on amylin analogs is described as physically different. GLP-1 reduces appetite noise, amylin does co-agonism.

I am going to push back on this slightly.

Small correction: the trial was 5 weeks, not 20. Does not change your point but people will quote it.

REDEFINE readouts are phase 23 data

About c/cagrilintide

Amylin analog pharmacology and the CagriSema combination: why amylin and GLP-1 co-agonism produces a different satiety profile, the REDEFINE readouts, and the very limited pool of people handling cagrilintide as research material.
