comment on unpopular opinion: most of what gets said here about reship is guesswork in c/vendorvetting · 8 points · 8 months ago

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.

comment on does New Zealand actually matter or is it forum lore at this point in c/glp1aus · 38 points · 9 months ago

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.

comment on purity — 9 things I got wrong before I got it right in c/coa · 48 points · 1 year ago

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.

comment on how much of what we believe about tapering actually comes from discontinuation threads in c/tapering · 54 points · 1 year ago

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

comment on the testing question that gets asked weekly, answered properly in c/vendorvetting · 7 points · 1 year ago

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.

comment on does fake COA actually matter or is it forum lore at this point in c/scamalerts · 97 points · 1 year ago

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.

comment on the batch question that gets asked weekly, answered properly in c/coa · 11 points · 1 year ago

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.

comment on unpopular opinion: most of what gets said here about certificate of analysis is guesswork in c/coa · 0 points · 1 year ago

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.

Left up.

Agreed — the database rather than the coverage, every time.

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

comment on order records — 5 things I got wrong before I got it right in c/vendorvetting · 149 points · 1 year ago

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

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

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.

Kept the script and the receipt for a private health claim and both were requested.
