comment on is the tirz appetite thing actually different or am i imagining it in c/tirzepatide · 12 points · 4 days ago

Right. And the sema-to-tirz "conversion" people post is invented. There is no published equivalence.

comment on telehealth prescriber asked me three questions and approved me. that is not care. in c/compounding · 13 points · 5 days ago

Push back: "compounded is fine because a pharmacy made it" skips every question this board exists to ask.

comment on why is nobody talking about the SURPASS-CVOT readout in c/tirzepatide · 33 points · 5 days ago

Yes. I stepped to 12.5 because the calendar said so, not because anything needed fixing, and I regretted it for a fortnight.

5kg over 23 weeks, never went past 10mg, and early fullness stayed mild the whole way. Posting because the loud threads are all 15mg.

Bacteriostatic or plain sterile water?

regional stock changes everything about transit

comment on [Vendor] JEEP six orders in, zero problems, and i am suspicious of my own luck in c/vendorvetting · 47 points · 18 days ago

The wider-market rows in the directory carry a band and a report count and nothing else, deliberately. Anything more would be manufacturing precision that the evidence does not support.

comment on my resting HR went from 58 to 66 on titration and settled back in c/tirzepatide · 12 points · 24 days ago

The distribution matters more than the mean. In the trial population the interquartile spread was wide enough that two honest people can have completely different runs on the same arm.

comment on [Question] does the vial concentration change how much dead space costs me in c/tirzepatide · 9 points · 27 days ago

week 8 is early to draw any conclusion at all

comment on the Zepbound question that gets asked weekly, answered properly in c/tirzepatide · 17 points · 29 days ago

This.

Not sure about this bit. The GIP arm being real does not tell you that it is what caused your particular week.

permalink

comment on how much of what we believe about mg/mL actually comes from reconstitution threads in c/reconstitution · 19 points · 1 months ago

Yes, and the dead-space point is worth repeating: it is small, it is real, and it is the same for every draw.

permalink

comment on shipping is the most under-discussed thing on this board in c/intlshipping · 15 points · 1 months ago

Disagree. That is a customs hold, not a carrier delay, and lumping them together makes the lane table wrong.

permalink

comment on genuine question about mg/mL that I am slightly embarrassed to ask in c/reconstitution · 21 points · 1 months ago

bacteriostatic water has the preservative, sterile water does not

permalink

comment on [Results] 65 weeks on 15mg, full numbers, ask me anything boring in c/tirzepatide · 2 points · 1 months ago

Correction to my own post above — I said 5mg and I have been on 2.5mg since the spring. Same argument, wrong number.

Did the lot code on the vial match the paperwork?

comment on [Lab] split one vial across PeptideMeter and VendorInvestigate — 98.4% and 97.2% in c/tirzepatide · 10 points · 1 months ago

a lot of people plateau nicely at 10mg and never need 15

Pushback on the syringe advice: a U-100 barrel reads units of volume. Calling them "doses" is how the confusion starts.

permalink

comment on three years of glucagon threads, summarised so you do not have to read them in c/survodutide · 47 points · 1 months ago

The escalation schedules in the published protocols are slow and deliberate, and the tolerability tables show why. That is a description of the trials rather than a suggestion for anybody.

permalink

comment on [Discussion] the bacteriostatic water advice in here is 3 years out of date in c/reconstitution · 5 points · 1 months ago

Correction: that gives 50 units, not what you have written. 30mg into 3mL is 10mg/mL and the division follows from there.

How many mg in the vial and how many mL are you adding?

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

the powder cake sits at the bottom, the volume you add is the volume that counts

permalink

comment on [PSA] PeptideMeter results are area% by default and people keep forgetting in c/tirzepatide · 5 points · 2 months ago

Weekly dosing again, half-life in the same neighbourhood as sema, so a step change takes about a month to reach steady state. Judging a new step at day five is judging noise.

comment on [Lab] split one vial across Medutest and Janoshik — 99.3% and 98.7% in c/tirzepatide · 5 points · 2 months ago

SURMOUNT-1 landed around 21% at 72 weeks on the top arm

comment on API source — 17 things I got wrong before I got it right in c/compounding · 188 points · 2 months ago

A 503A pharmacy compounds for an identified patient against a prescription. A 503B outsourcing facility registers with the regulator, may produce without patient-specific prescriptions, and is subject to current good manufacturing practice requirements. The two are governed differently and the difference is not cosmetic.

reship policy in writing before the order, not after

Adding the practical version: ask for lead time, minimum quantity and the batch record in the same message. Three answers, one email.

comment on [Meta] proposal — a flair for concentration posts in c/reconstitution · 274 points · 2 months ago

What concentration did you actually reconstitute at, rather than what did you intend to?

comment on why does nobody talk about dual agonist in c/survodutide · 19 points · 3 months ago

dual GLP-1 and glucagon agonist, and the glucagon arm is the story

permalink

comment on unpopular opinion: most of what gets said here about 15mg is guesswork in c/tirzepatide · 8 points · 3 months ago

The 21% figure is a 72-week mean on the highest arm. Quoting it as what someone should expect by week 33 is not a fair reading.

permalink

comment on reading 503B threads from 2024 and half of it aged badly in c/compounding · 32 points · 3 months ago

I would not read the price difference as a quality signal. Most of it is the consultation model, not the vial.

permalink

comment on [Discussion] hepatic fat is doing more work than we give it credit for in c/survodutide · 14 points · 3 months ago

I would not read across from the obesity programmes. Different population, different endpoint, different question.

permalink

comment on the units question that gets asked weekly, answered properly in c/reconstitution · 23 points · 3 months ago

Same. I got this wrong once, caught it because the units looked absurd, and have written on every vial since.

comment on [Discussion] the DHL advice in here is 3 years out of date in c/intlshipping · 52 points · 4 months ago

Median transit is the useful statistic. The minimum is a story about one shipment and the mean is dragged around by a single hold.

comment on [Lab] 4th independent test on JEEP — 97.3% on a claimed 97.0%, and the trend is the interesting part in c/tirzepatide · 2 points · 4 months ago

Same experience with the appetite effect being flatter across the week rather than front-loaded.

comment on [Lab] split one vial across Janoshik and Medutest — 98.1% and 98.9% in c/vendorvetting · 8 points · 4 months ago

Mild pushback: a supplier with fewer entries is not worse, it is less sampled. Those are different claims and the table says so.

comment on [Lab] split one vial across Janoshik and Medutest — 98.1% and 98.9% in c/vendorvetting · 6 points · 4 months ago

the wider-market names in the table are there because nobody has enough data on them

permalink

comment on [Results] 26 weeks, 9kg, and dual agonist was the hard part in c/tirzepatide · 0 points · 4 months ago

That percentage is body weight change, not body fat. Different measurement, and the distinction gets lost every time.
