why does nobody talk about biopsy

Question Cold Box ×7 Clean Column ×2

Right, the glucagon question again, but with numbers this time.

I have 18 data points over 20 weeks. The pattern is consistent enough that I do not think it is chance, and boring enough that nobody is going to screenshot it, which is usually a good sign.

The thing I would flag for anyone new: the effect I am describing showed up at week 93, not week 47. People give up long before the interesting part.

Interested in whether this matches other people's logs or whether I am an outlier.

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

Yeah, glucagon co-agonism is genuinely different.

u/renzo_asante205 points·1 year ago

This is correct. Do not generalise from tirzepatide.

u/liver_enzyme_liz122 points·1 year ago

Disagree but this is the good kind of wrong — it is specific enough to be checked.

Which trial arm?

u/tomas_lokken50 points·1 year ago

Which trial arm?

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

u/titration_marshalOPmod · c/semaglutide90 points·1 year ago

My version of this: I was so worried about the injection that I put it off for eleven days. The injection is the easiest part.

replysharereportpermalink
u/zeynep_ndiaye22 points·1 year ago

Strongly agree. The safety story is separate.

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

the MASH indication changes the risk calculus

I am going to push back on this slightly.

glucagon injection is a different vector than GLP-1

Phase 8 or 33?

Phase 8 or 33?

Yes, exactly this, and it is the bit that took me 94 weeks to accept.

Maintenance for 23 months now. Weight moves within about 3kg and the dose is a quarter of what it peaked at.

the safety profile is not just tirzepatide amplified

Not convinced. The evidence does not support that reading.

u/nadia_kjaer22 points·1 year ago

Maintenance for 23 months now.

Disagree on that part. 95.1% and 96.2% on the same vial is normal.
