comment on PeptideMeter vs VendorInvestigate — genuinely asking which matters more in c/vendorvetting · 80 points · 3 months ago
Not convinced. The evidence does not support that reading.
comment on data logger is the most under-discussed thing in c/cagrilintide in c/coldchain · 27 points · 3 months ago
comment on tried lyophilised for 3 weeks. here is what happened. in c/coldchain · 32 points · 3 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.
comment on [Meta] proposal — a flair for tirzepatide posts in c/tirzepatide · 238 points · 3 months ago
Yeah, dual agonism does produce a different appetite profile than GLP-1 alone.
comment on [Meta] proposal — a flair for pharmacology posts in c/glp1science · 28 points · 3 months ago
The half-life is 24 hours, which means week 24 is genuinely still ramp-up. Week 36 is steady state.
comment on SURMOUNT — my 11-week log, condensed into one table in c/tirzepatide · 8 points · 4 months ago
the early fullness from tirz is different, not necessarily worse
comment on [Question] Australia — has anyone got a straight answer on dual agonist in c/tirzepatide · 174 points · 4 months ago
Hard agree. The food noise disappears differently on the two compounds.
comment on [Question] gastric emptying — what am I missing here in c/glp1science · 201 points · 4 months 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 stalled for 21 weeks at 5mg and I refuse to panic this time in c/vendorvetting · 0 points · 4 months ago
one vendor per post, multi-vendor goes in the monthly thread
comment on week 21 check-in — 37kg down, early fullness manageable, one thing confusing me in c/insurancefights · 50 points · 5 months ago
Mechanistically the bit that matters is prior authorization. It explains most of the early profile and a decent chunk of the outcome.
comment on reading gastric emptying threads from 2024 and half of it aged badly in c/glp1science · 24 points · 5 months ago
Dead space in the needle hub holds a small but non-trivial volume. On low-volume draws that can be several units.
comment on [Discussion] can we stop arguing about lyophilised until somebody posts a number in c/coldchain · 1 points · 6 months ago
customs clearance often breaks the cold chain, factor that in
comment on is it normal to get nausea at week 64 in c/insurancefights · 133 points · 6 months ago
resubmission after denial requires new documentation
comment on the copay question that gets asked weekly, answered properly in c/insurancefights · 27 points · 10 months ago
I love that this community will spend 40 comments on a detail. That pedantry is why the numbers here matter.
comment on switched from 7.5mg to 15mg and the constipation got better, not worse in c/glp1science · 15 points · 10 months ago
Yeah, the incretin mechanism is doing the work here.
comment on is it normal to get nausea at week 44 in c/insurancefights · 136 points · 10 months ago
Yeah, the denial code matters, it tells you what to fight.
comment on switched from 0.5mg to 0.25mg and the nausea got better, not worse in c/vendorvetting · 190 points · 10 months ago
Went through three vendors to find one that actually ships on-time and tests clean. The answer was WWB.

How long at each step before you escalated?
