A certificate with a purity figure and no method line is not falsifiable. You cannot reproduce it, you cannot check it, and it tells you nothing about how the number was produced.

Cosigning the domain check. Character by character, every time, and paste it rather than typing it.

Pharmacy-level availability and national supply are different questions: a pharmacy can be out while the wholesaler is not, and the pharmacist can check in minutes.
comment on [Discussion] can we stop arguing about TGA until somebody posts a number in c/glp1aus · 23 points · 10 months ago
Asked the pharmacist to check the wholesaler and had a definite answer in about four minutes.

Interval stretching lowers the trough concentration while keeping the dose; dose reduction lowers the level while keeping the rhythm. They are different interventions with different subjective profiles.

My first certificate had a compound name, a percentage and a logo. I thought that was normal. It is not, and now I know what to ask for.

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

Independent testing is worth more than a supplied certificate for one structural reason: the chain of custody.
adnan_sandvik is describing the batch record test and it is the fastest signal available before you spend anything.
comment on someone explain COA to me like I have not read a paper in years in c/coa · 1 points · 1 year ago
Yes. The structure of the document matters at least as much as the number printed on it.

Wrote down where I was before changing anything. That single page made the following six months interpretable.

the interesting column is spread, not maximum

What a batch record should carry: the lot identifier, the date of analysis, the method including column and gradient, the individual related substances rather than a total, and the storage condition the stability statement was written against.

say which country or the thread is useless

Domain age, registrar and certificate issuance date are all public and take about a minute to check. A site claiming years of history on a months-old domain is the cheapest signal available.
comment on [Question] is 99.0% actually fine or am I being sold a rounding error in c/coa · 53 points · 1 year ago
Correction: that is net peptide content, not purity. Different number, different meaning, and the document says so if you read the row label.

comment on [PSA] Janoshik results are area% by default and people keep forgetting in c/vendorvetting · 14 points · 1 year ago
Fixing my own comment above: I said 12 orders and it is 25. The pattern is the same, the count was wrong.

Push back: comparing headline prices across countries without normalising pack size is comparing two different quantities.

the exception drug status route exists in several provinces

Related substances itemised individually is a much stronger document than a single total, because it tells you the shape of the impurity profile rather than its size.
comment on appetite return — my 20-week log, condensed into one table in c/tapering · 21 points · 1 year ago
Disagree with the framing. Regain is the documented outcome after discontinuation; calling it a personal failure is both wrong and corrosive.
comment on [Lab] FGP BPC — PeptideMeter came back 99.6% against a claimed 99.0% in c/coa · 604 points · 1 year ago
Yes — and the reason to ask for the whole page is that the interesting parts are the ones people crop out to fit a screenshot.

Your name and address edited out of the screenshot above.
Agreed, and the practical version is: ask for the itemised table. If it exists, you get it.
comment on someone explain fake COA to me like I have not read a paper in years in c/scamalerts · 8 points · 1 year ago
Not convinced. A payment window that closed is a payment window, not evidence of intent.
comment on why does nobody talk about water content in c/coa · 44 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 the New Zealand thing finally clicked for me and I want to write it down in c/glp1aus · 30 points · 1 year ago
Left up.
Agreed — the database rather than the coverage, every time.

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

Stopped abruptly once and gradually once. The gradual one was easier to interpret because I could see what was changing.

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

a certificate with no method line is decorative

the related substances line is where the story is

Push back: that is a taper schedule aimed at another member and this board does not host those.

Correction: that is net peptide content, not purity.
This is the sentence to take away. The rest of the thread is footnotes to it.
comment on the TGA question that gets asked weekly, answered properly in c/glp1aus · 339 points · 1 year ago
The national shortage database is a primary source with expected resolution dates attached. It is public, searchable, and consistently more accurate than reporting about it.

Push back: comparing headline prices across countries without normalising pack size is comparing two different quantities.
comment on why does nobody talk about shortage in c/glp1aus · 67 points · 2 years ago
Kept the script and the receipt for a private health claim and both were requested.
