comment on [Lab] 18th independent test on GL Biochem — 99.5% on a claimed 99.0%, and the trend is the interesting part in c/labresults · 33 points · 1 year ago
Small fix — same supplier, different lot. The two rows in the log are not the same batch.
comment on [Meta] proposal — a flair for special authorization posts in c/glp1canada · 11 points · 1 year ago
quantity limits are as common a barrier as coverage itself
comment on [Question] Janoshik — what am I missing here in c/labresults · 78 points · 1 year ago
That service reports area percent by default. Worth stating, since the thread has been comparing it to a mass figure.
comment on [Question] Janoshik — what am I missing here in c/labresults · 63 points · 1 year ago
Same.
Agreed — and two services on one batch is the strongest thing any of us can produce individually.
Slightly embarrassed to be asking this, but: Janoshik — what am I missing here. A series across separate lots estimates a process. Repeat tests on one lot estimate the…
comment on [Question] normal — what am I missing here in c/newbiequestions · 17 points · 1 year ago
Research-use-only material is not approved for human use. That is a plain statement of regulatory fact and it belongs in every beginner thread.
comment on the province thing finally clicked for me and I want to write it down in c/glp1canada · 3 points · 1 year ago
Yes. Approval and coverage are separate, and this board conflates them in about half its threads.
comment on 13 months in and basics are still the thing I get wrong in c/newbiequestions · 278 points · 1 year ago
titration means going slow on the way up
comment on someone explain special authorization to me like I have not read a paper in years in c/glp1canada · 31 points · 1 year ago
a rejected claim is not the same as a denied authorization
comment on switched from 0.25mg to 2.4mg and reflux got better, not worse in c/newbiequestions · 175 points · 1 year ago
Bacteriostatic water contains a preservative, which is what makes repeated entry into a vial reasonable. Sterile water does not, and the two are not interchangeable for that purpose.
comment on [Vendor] SSA order #5 — Sweden, 13 days, no drama, receipts inside in c/cryptopay · 118 points · 1 year ago
Escrow is not standard in this space. Wanting it is reasonable; expecting it as default is not.
comment on unpopular opinion: most of what gets said here about USDC is guesswork in c/cryptopay · 96 points · 1 year ago
Same. Asking which networks are accepted before ordering has saved me twice.
comment on why does nobody talk about water content in c/coa · 140 points · 1 year ago
Right, and net peptide content is where the counterion and the water go. Both numbers can be honest and very different.
comment on the UK: network, and what it actually costs here in c/cryptopay · 14 points · 1 year ago
Agreed. Network first, address second, amount third, and in that order every time.
comment on [Lab] split one vial across Janoshik and Medutest — 98.1% and 97.6% in c/coa · -31 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 help me understand batch, I have read the wiki twice in c/coa · -20 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 first time thing finally clicked for me and I want to write it down in c/newbiequestions · 4 points · 1 year ago
Did you write the concentration on the vial?
comment on the first time thing finally clicked for me and I want to write it down in c/newbiequestions · 3 points · 1 year ago
What week are you in?
the first time thing finally clicked for me and I want to write it down, which sounds obvious until you try to state the evidence for it. Nothing on this board is…
comment on unpopular opinion: most of what gets said here about Canada is guesswork in c/glp1canada · 1 points · 1 year ago
the same product can be covered in one province and not the next
comment on [Question] how do you actually verify gas fees in c/cryptopay · 1 points · 1 year ago
A test transaction costs one extra network fee and verifies the address, the network and the recipient’s crediting process before the main amount moves.
comment on [Results] 16 weeks, 5kg, and basics were the hard part in c/newbiequestions · 58 points · 1 year ago
Nothing on this board is medical advice, and the people answering you — including me — are members with spreadsheets rather than clinicians.
Slight disagreement with this bit only, because a beginner reading it might take it as a plan rather than a description.
comment on help me understand area percent, I have read the wiki twice in c/coa · 135 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 how much of what we believe about batch actually comes from purity threads in c/coa · 1k points · 1 year ago
Asked ERP for the batch-specific certificate and had the full document — batch, date, method line naming the column — inside six hours. That is now my baseline for everybody.
comment on [Discussion] we are measuring network at the wrong time and calling it noise in c/cryptopay · 62 points · 2 years ago
I would not treat a delayed confirmation as evidence of anything at all. Chains have busy hours.
comment on [Discussion] the purity advice in here is 2 years out of date in c/labresults · 44 points · 2 years ago
vendor, compound, batch, service, result — that is the template
comment on purity is the most under-discussed thing on this board in c/coa · 160 points · 2 years ago
The document I was worried about turned out to be a re-issue with a later creation date. Asked, got the original, entirely ordinary.
comment on [Discussion] related substances are doing more work than we give it credit for in c/coa · 276 points · 2 years ago
Yes. The structure of the document matters at least as much as the number printed on it.
comment on three years of special authorization threads, summarised so you do not have to read them in c/glp1canada · 10 points · 2 years ago
Provincial plan, employer plan, or paying cash?
comment on [Lab] 14th independent test on GGPeps — 98.3% on a claimed 97.5%, and the trend is the interesting part in c/labresults · 9 points · 2 years ago
net peptide content if the report gives it, and say which you are quoting
comment on [Discussion] network is doing more work than we give it credit for in c/cryptopay · -7 points · 2 years ago
send a test amount first if the total is large
comment on how much of what we believe about COA actually comes from area percent threads in c/coa · 27 points · 2 years ago
net peptide content and purity are two different numbers on the same vial
comment on reading area percent threads from 2024 and half of it aged badly in c/coa · 56 points · 2 years ago
redact your own name, never the batch details
comment on [Discussion] the related substances advice in here is 3 years out of date in c/coa · 115 points · 2 years ago
Disagree that a lower number is automatically worse. A conservative claim that survives testing is worth more than an optimistic one that does not.
comment on [Question] New Zealand — has anyone got a straight answer on chargeback in c/cryptopay · 92 points · 2 years ago
Which networks did they list as accepted?
comment on three years of USDC threads, summarised so you do not have to read them in c/cryptopay · 9 points · 2 years ago
Right, and confirmations are the status. "Sent" means nothing until the chain agrees.
comment on [Discussion] can we stop arguing about batch until somebody posts a number in c/coa · 40 points · 2 years ago
Did you ask for the batch-specific document, or is this the catalogue one?
Adding the bit that always gets missed: the lot on the vial has to match the lot on the page, or none of this applies to your material.
comment on below spec — 22 things I got wrong before I got it right in c/labresults · 32 points · 2 years ago
Chain of custody is why member-funded testing is worth more than a supplied certificate: the vial tested is the vial that arrived at a member’s door.
comment on [Lab] 16th independent test on WXT — 99.3% on a claimed 98.5%, and the trend is the interesting part in c/coa · 70 points · 2 years ago
the lot on the vial has to match the lot on the page
