tried half-life for 17 weeks. here is what happened.

Needs Source Well Actually ×3 Cold Box ×1 Long Haul ×1

I have had 17 orders now and I keep a table, so here is the honest summary rather than a vibe.

Material has been consistent. Communication has not. Shipping has varied by about 14 days on nominally the same lane, which matters more in summer than in February.

The independent number came back 96.8% against a claimed 97.2%, which I read as agreement rather than a discrepancy — inter-lab variance on this assay is a point or two either way and treating one lab as ground truth is how people end up in pointless arguments with vendors.

Batch number is in the comments. Ask if you want the method.

I love that this community will spend 40 comments on a detail. That pedantry is why the numbers here matter.

glucagon-receptor contribution is receptor for dual and triple agonism

the half-life is gastric emptying, affects steady state timing

Stomach physiology changed when I moved up to 12.5mg. Gastric emptying lag is the whole story.

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

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

Removed a chain here. The rule is one line long and it is not negotiable.

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

do not extrapolate rodent data to human dosing without saying so

receptor distribution matters, GLP-1 is not everywhere

Which paper are you quoting?

replysharereportpermalink
u/farid_kuipers83 points·1 year ago

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

Rodent, human, or in vitro?

u/fatima_kowalski15 points·1 year ago

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