comment on [Country Guide] personal import rules, my country, with the actual citations in c/customs · 167 points · 3 days ago

Research-use-only labelling is a description of intended use, not a customs classification. It does not by itself determine how anything is treated at a border.

comment on [Question] interval stretching vs dose reduction — is either better in c/tapering · 5 points · 7 days ago

I would not treat appetite returning as a sign of doing it wrong. It is the expected sequence.

comment on [Question] interval stretching vs dose reduction — is either better in c/tapering · 12 points · 9 days ago

A written baseline — dose, date, weight, waist, and how appetite feels — taken before any change is what makes the following months interpretable rather than a series of impressions.

comment on [Explainer] the four things a COA must have or it is decorative in c/coa · 126 points · 16 days ago

The PDF creation date being later than the analysis date is usually a re-issue or a re-export. It is worth one question and it is not evidence of anything on its own.

comment on [Question] how long were you on before you tapered in c/tapering · 15 points · 17 days ago

appetite comes back before the weight does

comment on [Vendor] MKM — five tests, four compounds, nothing outside the band in c/vendorvetting · 2 points · 1 months 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 [PSA] batch is not what most of this community thinks it is in c/coa · 134 points · 1 months ago

Did you get the chromatogram or only the summary line?

comment on does water content actually matter or is it forum lore at this point in c/coa · 1 points · 1 months ago

What does the method line actually say? Not the technique — the column and the gradient.

permalink

comment on group buy organiser vanished with 3.4k. here is the timeline in c/vendorvetting · 37 points · 1 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.

comment on [Meta] proposal — a flair for Janoshik posts in c/vendorvetting · 5 points · 2 months ago

Paradigm Peptide shows up in threads constantly and has almost nothing on file

comment on [PSA] Medutest results are area% by default and people keep forgetting in c/vendorvetting · -7 points · 2 months ago

Did you ask for the batch-specific certificate, or the generic one?

permalink

comment on why does nobody talk about area percent in c/coa · -36 points · 2 months ago

Are the related substances itemised or is it a single total?

permalink

comment on the COA thing finally clicked for me and I want to write it down in c/coa · 40 points · 2 months ago

Sent one vial to PeptideMeter and VendorInvestigate. 99.4% and a claimed 99.0%. Cost me more than the vial and I would do it again.

permalink

comment on 8 months in and amylin is still the thing I get wrong in c/cagrilintide · 1 points · 3 months ago

Independent purity data on this compound is sparse compared with the older molecules, simply because far fewer members have paid for testing. Sparse data means wide uncertainty, not a verdict.

comment on [Meta] the customs rule is doing its job and people should stop complaining in c/customs · 19 points · 3 months ago

Ordered from the warehouse in Spain and the whole import question disappeared. 15 days, domestic, no notice, nothing to manage.

permalink

comment on [Discussion] we are measuring COA at the wrong time and calling it noise in c/coa · 26 points · 3 months 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 [Discussion] can we stop arguing about interval stretching until somebody posts a number in c/tapering · 1 points · 4 months ago

Stretched from seven days to ten to twelve over four months. Appetite told me where the limit was each time.

comment on [Lab] split one vial across Janoshik and Medutest — 98.1% and 98.9% in c/vendorvetting · 0 points · 4 months 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 does VendorInvestigate actually matter or is it forum lore at this point in c/vendorvetting · 35 points · 4 months ago

Started buying small deliberately, tested every lot for the first four, then stopped testing every lot because there was nothing to find.

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

Correcting myself upthread: I gave the 22-week figure and the paper reports 68 weeks.

comment on [Lab] 10th independent test on ERP — 97.2% on a claimed 97.0%, and the trend is the interesting part in c/coa · 20 points · 6 months ago

Spent four months confusing area% and mass% in every post I made here. One explainer thread and it clicked permanently.

Is there any independent purity data on this compound that you have seen?

Are you comparing against a GLP-1 monotherapy result? They are not comparable.

comment on how much of what we believe about reship actually comes from Janoshik threads in c/vendorvetting · 92 points · 6 months ago

Fixing my own comment above: I said 11 orders and it is 32. The pattern is the same, the count was wrong.

Not convinced by the ranking-by-vibe approach here. The community number is derived from reports; your feeling is derived from four posts you remember.

comment on COA — 5 things I got wrong before I got it right in c/coa · 104 points · 6 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.

That is a report count, not a test count. The table lists both and they are very different numbers.

comment on [Question] is 98.0% actually fine or am I being sold a rounding error in c/vendorvetting · -35 points · 6 months ago

Sent the same compound from SGN and ERP to Janoshik in the same month. Both came back above the claim on the certificate — mine was 99.0% on a stated 98.5%.

comment on help me understand order records, I have read the wiki twice in c/vendorvetting · 19 points · 7 months ago

Careful. "Nobody has tested Amino Asylum" is a statement about this board, not about the supplier. Say the first thing, not the second.

comment on [Discussion] can we stop arguing about related substances until somebody posts a number in c/coa · 21 points · 7 months ago

Cosigning. The batch identifier is load-bearing, and a certificate that cannot be tied to the vial in your hand is not about your vial.
