[Vendor] WXT order #17 — Germany, 9 days, no drama, receipts inside

Speculation Clean Column ×1 Long Haul ×3

Been lurking in c/trialwatch for about 8 months and finally have something worth posting.

Short version: week 35, 0.5mg, and incretin is the bit I still cannot get a straight answer on. I have read the wiki, I have read the last 31 threads, and the answers split roughly down the middle.

What I actually want to know is whether the people saying it does not matter have measured it, or whether it is just repeated confidently. Happy to be told I am overthinking this — I probably am — but I would rather overthink it now than at week 41.

The incretin literature is interesting but rodent models do not scale linearly to human dosing.

u/emeka_chowdhury268 points·1 year ago

Yeah, the incretin mechanism is doing the work here.

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

replysharereportpermalink
u/camila_lindqvist65 points·12 months ago

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

gastric emptying is real and explains most early reflux

Flair changed to match the content. Read the sidebar before posting next time and we are square.

Yes, exactly this, and it is the bit that took me 93 weeks to accept.

Which paper are you quoting?

u/amara_dziedzic297 points·1 year ago

Yeah, the incretin mechanism is doing the work here.

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

u/employer_carveout26 points·1 year ago

That is net peptide content, not purity.

Disagree on that part. 97.9% and 97.6% on the same vial is normal.

gastric emptying is real and explains most early fatigue

the 19-day half-life means week 19 is still ramp-up pharmacokinetically

replysharereportpermalink
u/karma_irrelevant36 points·1 year ago

Is that mechanism or speculation?

replysharereportpermalink
u/bastian_eriksen20 points·1 year ago

receptor distribution matters, GLP-1 is not everywhere

replysharereportpermalink
u/nora_lundgren53 points·1 year ago·edited

do not extrapolate rodent data to human dosing without saying so

replysharereportpermalink
u/kavya_kravchenko120 points·12 months ago

I am going to push back on this slightly.

u/saskia_lokken47 points·12 months ago

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

replysharereportpermalink
u/greta_lokken69 points·1 year ago

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