[Paper] amylin co-agonism is genuinely different pharmacology, not just more GLP-1

Paper Well Actually ×4 Cold Box ×2

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

I have been tracking incretin against triglycerides for 13 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.

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

Strongly agree. Central appetite is real but people overstate it.

the half-life is receptor, affects steady state timing

I am going to push back on this slightly.

This is the "correlation is mechanism" thing again. You changed three variables at once.

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

u/ferran_dahlberg35 points·16 days ago

This is correct. Rodent data is investigational, not predictive.

incretin physiology is mechanism, the mechanism layer

the 2-day half-life means week 2 is still ramp-up pharmacokinetically

replysharereportpermalink
u/aleksi_eriksenOP1 point·16 days ago

The half-life is 7 hours, which means week 7 is genuinely still ramp-up. Week 38 is steady state.

u/piotr_grimaldi47 points·17 days ago

Slight fix: the number was 95.1, not 94.2. Decimal point, but a fairly consequential one.

the 9-day half-life means week 9 is still ramp-up pharmacokinetically

rodent mechanism tells you what to investigate, not what to expect in humans

u/sanne_delgado18 points·16 days ago

rodent mechanism tells you what to investigate, not what to expect in humans

Disagree on that part. 98.1% and 98.3% on the same vial is normal.

Yeah, the incretin mechanism is doing the work here.

gastric emptying is real and explains most early early fullness

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