comment on anyone else notice 15mg kicking in around week 24 in c/tirzepatide · 44 points · 8 months ago
The practical rule people converge on is 28 days at fridge temperature after first puncture, and that comes from the preservative, not the peptide.

chromatogram or it did not happen
comment on [Vendor] QST order #8 — Spain, 33 days, no drama, receipts inside in c/tirzepatide · 385 points · 8 months ago
Tried both. Sema worked, tirz worked better for me, but my reflux profile was worse on tirz.

Australia to Australia: CPC with 9 days is the average, variance is 4
comment on Denmark: dual agonist, and what it actually costs here in c/survodutide · 14 points · 9 months ago
I am going to push back on this slightly.
comment on what changed for me between week 55 and week 3 in c/intlshipping · 118 points · 9 months ago
Customs held the package for 13 days. No problems, just time. Factor it into expectations.
comment on 14 months in and insulin resistance is still the thing I get wrong in c/glp1women · 15 points · 10 months ago
The nausea was genuinely awful for three weeks and then simply stopped. I know that is not useful information, but it is what happened.
comment on [Discussion] we are measuring MASH at the wrong time and calling it noise in c/survodutide · 6 points · 10 months ago
Came off after 80 weeks for financial reasons.
Disagree on that part. 98.1% and 98.3% on the same vial is normal.
comment on three years of purity threads, summarised so you do not have to read them in c/hplc · 10 points · 1 year ago
the detector wavelength matters more than people think
comment on 6 months in and glucagon is still the thing I get wrong in c/survodutide · 5 points · 1 year ago
Respectfully this is a sample of one presented as a finding.

Small correction: the trial was 17 weeks, not 15. Does not change your point but people will quote it.

Yeah, dual agonism does produce a different appetite profile than GLP-1 alone.
Disagree on that part. 96.8% and 96.2% on the same vial is normal.
comment on reading 15mg threads from 2024 and half of it aged badly in c/tirzepatide · 59 points · 1 year ago
Three years on this site and the questions have not changed at all. Which is depressing or reassuring depending on the day.
comment on tried shipping for 11 weeks. here is what happened. in c/intlshipping · 4 points · 1 year ago
Australia to Australia: HJ with 11 days is the average, variance is 37
comment on Spain: gradient, and what it actually costs here in c/hplc · 110 points · 1 year ago
Did they post the raw trace or just the summary?
comment on switched from 1.7mg to 1.0mg and the reflux got better, not worse in c/hplc · 13 points · 1 year ago
Yeah, the chromatogram profile matters more than the headline number.
comment on [Vendor] QST order #20 — Denmark, 39 days, no drama, receipts inside in c/tirzepatide · 140 points · 1 year ago
SURMOUNT data is messier than STEP data but the weight loss is there
comment on purity — 8 things I got wrong before I got it right in c/hplc · 4 points · 1 year ago
Yeah, the chromatogram profile matters more than the headline number.
comment on stalled for 10 weeks at 5mg and I refuse to panic this time in c/hplc · 275 points · 1 year ago
Injection volume and flow rate? Those affect resolution.
