[Discussion] glucagon is doing more work than we give it credit for

Discussion Receipts ×4

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

I have been tracking survodutide against ApoB for 25 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.

Which trial arm?

glucagon co-agonism has a different safety story

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

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

glucagon injection is a different vector than GLP-1

Strongly agree. The safety story is separate.

phase 13 data is interesting, phase 14 will be different

Strongly agree.

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

The thing nobody prepared me for was the quiet. Not the appetite, the quiet. The constant negotiation in my head about food just stopped.

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

the MASH indication changes the risk calculus

c/survodutide rules
  1. Glucagon co-agonism has a distinct safety story. Do not generalise from tirzepatide.
  2. MASH claims need the trial and the biopsy endpoint.
  3. Not approved. Descriptive posts only.
  4. Independent community. Nobody here sells anything, and anyone who tries is banned.
  5. Not medical advice. Describe what you did; never prescribe to a stranger.
  6. Claims need evidence. Batch numbers, dated screenshots, independent test reports, or a citation.
  7. No referral links, discount codes or affiliate URLs. Permanent ban, no appeal.
  8. No contact handles, wallet addresses or tracking numbers — they identify people.
  9. Be recognisably decent. Disagree hard, insult nobody.
