[Lab] SSA BPC — Medutest came back 97.4% against a claimed 98.3%

Question Cold Box ×3 Well Actually ×1

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

I have been tracking incretin against eGFR for 3 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.

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

Rodent, human, or in vitro?

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

Which paper are you quoting?

u/emeka_chowdhury-6 points·1 year ago

Yeah, the incretin mechanism is doing the work here.

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

Not to be pedantic but gastric emptying and mechanism are being used interchangeably and they are not interchangeable in real life.

receptor distribution matters, GLP-1 is not everywhere

Slight fix: the number was 98.1, not 98.0. Decimal point, but a fairly consequential one.

Not convinced. The evidence does not support that reading.

the 13-day half-life means week 13 is still ramp-up pharmacokinetically

Edit to your parent would help — the concentration you quoted assumes one scenario and you have written another above it.
