Ordered under a name that turned out to cover two different molecules. Nobody’s fault but mine for not asking.

lead times on unusual lines are the thing to confirm up front
comment on does purity actually matter or is it forum lore at this point in c/coa · 12 points · 6 months ago
Are the related substances itemised or is it a single total?
comment on [Discussion] can we stop arguing about PeptideMeter until somebody posts a number in c/vendorvetting · 25 points · 6 months ago
consistency across lots beats one spectacular result
comment on [Question] Mounjaro — what am I missing here in c/tirzepatide · 257 points · 6 months ago
Right. And the sema-to-tirz "conversion" people post is invented. There is no published equivalence.
comment on help me understand shortage, I have read the wiki twice in c/glp1aus · 4 points · 7 months ago
PBS listing and TGA registration are two different questions
comment on someone explain New Zealand to me like I have not read a paper in years in c/glp1aus · 1 points · 8 months ago
That figure is a private price at one pharmacy, not a national one.
comment on switched from 5mg to 15mg and constipation got better, not worse in c/tirzepatide · 61 points · 8 months ago
2.5 is the starter dose and it is not meant to be the dose that works
comment on genuine question about PeptideMeter that I am slightly embarrassed to ask in c/vendorvetting · 44 points · 8 months ago
Which lane, and what was the quoted lead time at checkout?
comment on [Question] New Zealand — has anyone got a straight answer on shortage in c/glp1aus · 12 points · 8 months ago
Agreed that the published criteria are the authority. They are searchable and most people never look.
comment on [Lab] 12th independent test on QST — 98.6% on a claimed 98.5%, and the trend is the interesting part in c/coa · 123 points · 8 months ago
the lot on the vial has to match the lot on the page
comment on [Discussion] can we stop arguing about water content until somebody posts a number in c/coa · 37 points · 10 months ago
Does the lot on the vial match the lot on the page?
comment on [Question] related substances — what am I missing here in c/coa · 94 points · 10 months ago
ask for the storage condition the stability statement was written against
comment on unpopular opinion: most of what gets said here about purity is guesswork in c/coa · 0 points · 11 months ago
Ask what the stability statement was written against — temperature, light, and whether it was the lyophilised powder or the reconstituted solution. Those are three different claims.
comment on SURMOUNT: what the trials say vs what this community says in c/tirzepatide · 68 points · 11 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.
comment on the testing question that gets asked weekly, answered properly in c/vendorvetting · 6 points · 1 year ago
Started buying small deliberately, tested every lot for the first four, then stopped testing every lot because there was nothing to find.
comment on how much of what we believe about Mounjaro actually comes from SURMOUNT threads in c/tirzepatide · 59 points · 1 year ago
Agreed, and the trial number is a mean of a very wide distribution — the tails are enormous and nobody posts from the middle.
comment on how much of what we believe about Mounjaro actually comes from SURMOUNT threads in c/tirzepatide · 41 points · 1 year ago
The 21% figure is a 72-week mean on the highest arm. Quoting it as what someone should expect by week 29 is not a fair reading.
comment on how much of what we believe about purity actually comes from related substances threads in c/coa · 150 points · 1 year ago
Ask what the stability statement was written against — temperature, light, and whether it was the lyophilised powder or the reconstituted solution. Those are three different claims.
comment on [Question] area percent — what am I missing here in c/coa · 142 points · 1 year ago
axis labels included, always
comment on [Discussion] the vendor advice in here is 3 years out of date in c/vendorvetting · 458 points · 1 year ago
Where a supplier holds regional stock, ask which lines are actually held there rather than drop-shipped. It changes the lead time and it changes the customs question.
comment on reading New Zealand threads from 2024 and half of it aged badly in c/glp1aus · -24 points · 1 year ago
compounded supply arrangements changed and the threads have not caught up
comment on [Discussion] we are measuring VendorInvestigate at the wrong time and calling it noise in c/vendorvetting · 12 points · 1 year ago
Agreed — and the corollary is that "no data" and "bad data" have to be written differently.
This is the whole method in one sentence. Everything else in the thread is elaboration.
comment on [Question] is 93.7% actually fine or am I being sold a rounding error in c/tirzepatide · 133 points · 1 year ago
Went 10 to 12.5 on the calendar and had the worst fortnight of the whole run. Dropped back to 10 and everything settled.
comment on [Discussion] the purity advice in here is 3 years out of date in c/coa · 291 points · 1 year ago
Area percent is the peak area of your compound over the total integrated area, at one wavelength, on one gradient. It is a relative measure of what the detector saw, not a mass fraction of the vial.
comment on [Lab] SSA tirz — Medutest came back 98.2% against a claimed 97.5% in c/vendorvetting · 1 points · 1 year ago
Peptidology shows up in threads constantly and has almost nothing on file
comment on [Lab] 20th independent test on QYB — 97.9% on a claimed 97.0%, and the trend is the interesting part in c/vendorvetting · 113 points · 1 year ago
Is that from the source page log or from memory?
comment on [Lab] 20th independent test on QYB — 97.9% on a claimed 97.0%, and the trend is the interesting part in c/vendorvetting · 153 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 why does nobody talk about water content in c/coa · 172 points · 1 year ago
That is the catalogue certificate rather than the batch-specific one. Same layout, completely different status.
comment on help me understand Medutest, I have read the wiki twice in c/vendorvetting · 1 points · 1 year ago
That is a report count, not a test count. The table lists both and they are very different numbers.
comment on [Discussion] the related substances advice in here is 2 years out of date in c/coa · 87 points · 1 year ago
Ask what the stability statement was written against — temperature, light, and whether it was the lyophilised powder or the reconstituted solution. Those are three different claims.
comment on [Discussion] the PBS advice in here is 3 years out of date in c/glp1aus · 1 points · 1 year ago
Registration by the therapeutic goods regulator establishes that a product may be supplied. Subsidy listing is a separate decision about public funding, with its own criteria and its own timetable.
comment on [PSA] testing is not what most of this community thinks it is in c/vendorvetting · 174 points · 1 year 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 [Question] how do you actually verify Mounjaro in c/tirzepatide · 1 points · 1 year ago
zepbound and mounjaro are the same compound with different labels
comment on help me understand compounding, I have read the wiki twice in c/glp1aus · 16 points · 1 year ago
the shortage listing has an expected resolution date on it
comment on three years of water content threads, summarised so you do not have to read them in c/coa · -10 points · 1 year ago
a total of 0.4% tells you less than four named impurities adding to 0.6%
comment on [Discussion] dual agonist is doing more work than we give it credit for in c/tirzepatide · 20 points · 1 year ago
the appetite effect is blunter than sema, in a good way, most weeks
comment on anyone else notice GIP kicking in around week 81 in c/tirzepatide · 50 points · 1 year ago
Yes — 10mg being a genuine landing place for a lot of people is underrated. There is no medal for 15.
comment on help me understand handling, I have read the wiki twice in c/researchpeptides · 61 points · 1 year ago
Stocked lines and made-to-order lines have different lead times and different storage histories. Both are ordinary; the difference is worth confirming before you commit.
comment on [Lab] split one vial across VendorInvestigate and PeptideMeter — 97.2% and 96.8% in c/coa · 133 points · 1 year ago
Started keeping a folder of every certificate I have been sent. The ones that itemise impurities are a small group and they are mostly the same suppliers.
