comment on carrier — 23 things I got wrong before I got it right in c/intlshipping · 160 points · 5 months ago

Ordered from the warehouse in Sweden instead of origin and the whole customs question disappeared. 4 days, door to door.

Same lane in a different season for comparison?

Agree. The verification log is the part with the checkable facts in it; the number at the top is just a summary of a lot of averaging.

This. Ask for the batch record. The ones who send it inside a day have told you more than any review could.

comment on the units thing finally clicked for me and I want to write it down in c/reconstitution · 185 points · 6 months ago

Aim the stream down the wall of the vial rather than into the cake. Reconstitution is a solubility problem, not a mixing problem, and mechanical shear does nothing helpful.

comment on [Question] is 98.0% actually fine or am I being sold a rounding error in c/vendorvetting · 5 points · 6 months ago

Agree.

Would qualify this slightly. Fewer entries means less sampling, and less sampling is not the same as a worse process.

comment on [Question] Mounjaro — what am I missing here in c/tirzepatide · -31 points · 6 months ago

Vials and pens carry the same molecule; what differs is fill volume, device tolerance and whether you are doing your own arithmetic. Neither is inherently more accurate.

switching from sema is not a dose conversion, there is no clean equivalence

comment on someone explain vendor to me like I have not read a paper in years in c/vendorvetting · 1 points · 7 months ago

Inter-lab variance on this assay runs a point or two either way. Two services disagreeing by that much is agreement, not a discrepancy, and treating it otherwise starts pointless arguments.

Small fix: SURMOUNT is the obesity programme, SURPASS is the type-2 programme. They are different endpoints and the numbers do not transfer.

Kept a spreadsheet of quoted versus actual lead time across 16 orders. The quoted number held.

comment on dead space is the most under-discussed thing on this board in c/reconstitution · 9 points · 8 months ago

Not quite. Bacteriostatic and sterile water are not interchangeable for a multi-draw vial, and the difference is the preservative.

permalink

comment on [Question] how do you actually verify reconstitution in c/reconstitution · 124 points · 8 months ago

That is sterile water, not bacteriostatic. Same appearance, different product, and it matters for a multi-draw vial.

Cosigning the beyond-use date question. What it is based on tells you whether anybody has done stability work.

Correcting my own comment: the shortage status changed in the interim, so the arrangement I described no longer applies.

Was there potency testing on the finished preparation, or only on the starting material?

comment on how much of what we believe about 503B actually comes from compounding threads in c/compounding · 0 points · 10 months ago

Yes — asking which facility, by name, is the single most useful question and most clinics will answer it.

Adding one thing — ask for the facility name. Most will give it, and the ones that will not have answered you.

comment on [Discussion] we are measuring lane at the wrong time and calling it noise in c/intlshipping · 1 points · 10 months ago

Careful — the supplier does not control the last mile and most of your variance is in it.

permalink

comment on [Results] 74 weeks, 23kg, and GIP was the hard part in c/tirzepatide · 91 points · 10 months ago

2.5mg is a four-week starting dose, not a maintenance dose. Worth being precise since people search these threads.

I keep a laminated card in the drawer with the arithmetic on it. Looks ridiculous. Has never once let me draw the wrong volume.

Concentration on the compounded vial was different from what I had been using and I nearly did the arithmetic on autopilot.

comment on reship — 19 things I got wrong before I got it right in c/intlshipping · 83 points · 11 months ago

Same lane, four orders, 8 to 12 days, all four within a couple of days of the quote. That consistency is the actual finding.

comment on week 36 check-in — 6kg down, sulphur burps manageable, one thing confusing me in c/tirzepatide · 115 points · 12 months ago

It is a dual GIP and GLP-1 receptor agonist, and the GIP arm is the part that has no equivalent in the semaglutide threads. That is why the side-effect profile reads differently rather than just milder.
