comment on [Results] 47 weeks, 15kg, and GIP was the hard part in c/tirzepatide · 7 points · 1 year ago

Did you come to this from sema, and if so how long was the gap?

comment on [Vendor] WXT order #15 — Germany, 12 days, no drama, receipts inside in c/coldchain · 28 points · 1 year ago

Gel packs are designed for a duty cycle. A liquid pack at the end of a longer-than-expected transit is a pack behaving as specified, not evidence of an excursion in the vial.

comment on [Question] Medutest — what am I missing here in c/vendorvetting · 8 points · 1 year ago

Disagree that reviews are worthless. They are worthless when they say "fast shipping A+++". A dated one naming a compound and a document is evidence.

comment on order records — 5 things I got wrong before I got it right in c/vendorvetting · 1 points · 1 year ago

the source page log is more useful than the score above it

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

ask for the batch record before you ask for a discount

Sent the same compound from SGN and GGPeps to Medutest in the same month. Both came back above the claim on the certificate — mine was 99.5% on a stated 99.0%.

comment on [Discussion] order records are doing more work than we give it credit for in c/vendorvetting · 1 points · 2 years ago

Yes, and the reason the wider-market table has no scores is that a score built on two reports would be a lie with a decimal point.

comment on [Discussion] the Janoshik advice in here is 3 years out of date in c/vendorvetting · 235 points · 2 years ago

Agreed on buying small first. The cost of a test is small next to the cost of committing to a supplier you have not checked.

external review exists and almost nobody uses it

appeal in writing even when they say a call is enough

What exactly does the denial letter give as the reason?

comment on [Vendor] QST vs WWB on the same compound, same month — both cleared 99.0% in c/tirzepatide · 88 points · 2 years ago

2.5 is the starter dose and it is not meant to be the dose that works

comment on [Vendor] GGPeps order #16 — Ireland, 13 days, no drama, receipts inside in c/coldchain · 116 points · 2 years ago

transit temperature is a distribution, not a number

ask for the denial reason in writing, always

comment on [Meta] the tirzepatide rule is doing its job and people should stop complaining in c/tirzepatide · 1 points · 2 years ago

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

Disagree with the conversion table. There is no validated equivalence between the two molecules and posting one as though there is does real damage.

comment on tirzepatide: the version I wish someone had shown me in week 1 in c/tirzepatide · 228 points · 2 years ago

SURMOUNT-1 ran 72 weeks with the top arm around 21% mean body weight change. SURPASS is the diabetes programme and reports glycaemic endpoints, so quoting the two interchangeably is a category error.

Asked a question here that I thought was stupid and got three papers back. Best thread I have been in on this site.

comment on why does nobody talk about reship in c/vendorvetting · 61 points · 2 years ago

Regional stock made more difference to my planning than anything else — ordering from a warehouse in the UK took the customs question off the table entirely.

comment on why does nobody talk about reship in c/vendorvetting · 78 points · 2 years ago

Small fix — the figure you quoted is the claimed purity from the certificate, and the independent result was the higher of the two.

Disagree that reviews are worthless.

Agreed — and the corollary is that "no data" and "bad data" have to be written differently. The table separates them for exactly that reason.

a warm gel pack tells you the pack failed, not that the material did

the excursion that matters is the one after reconstitution

comment on [PSA] excursion is not what most of this community thinks it is in c/coldchain · 48 points · 2 years ago

Wrote the reconstitution date on the vial for the first time last year. Have never once since wondered how old a solution is.

comment on someone explain Medutest to me like I have not read a paper in years in c/vendorvetting · 95 points · 2 years ago

Kept a spreadsheet of quoted versus actual lead time across 6 orders. The quoted number held.
