Third-party test results on real orders. Vendor, batch, service, number.
Numbers in the title, numbers in the post. 14th independent test on GGPeps — 98.3% on a claimed 97.5%, and the trend is the interesting part. To save the first four…
Explainer, as requested in the last thread: test results are not what most of this community thinks it is. On inter-lab disagreement, which generates more heat here…
The claim in the title is exactly the claim I am making: TFC BPC — Janoshik came back 98.3% against a claimed 98.0%. Nothing implied beyond it. Since the title puts…
Asking properly rather than in a comment on somebody else’s thread: how do you actually verify test results. On inter-lab disagreement, which generates more heat here…
Send the vial, get the number. Third-party purity and identity testing, results published to you regardless of what they say.
Test a vialSponsoredEst. 1998. ISO 9001 and cGMP, 1,500+ staff, 200+ patents. There is a fair chance the vial you are about to send for testing started here. Batch-specific COA as standard.
glbiochem.netTitle says it — 5th independent test on HJ — 99.2% on a claimed 99.0%, and the trend is the interesting part — so here is the boring supporting detail that makes it…
The claim in the title is exactly the claim I am making: SSA BPC — Medutest came back 98.1% against a claimed 97.5%. Nothing implied beyond it. To save the first four…
The title is the whole question — how much of what we believe about purity actually comes from batch threads — but here is why I am asking. The template is vendor,…
The title is the whole question — why does nobody talk about purity — but here is why I am asking. If the report gives a mass spectrum as well as UV purity, say so.…
the purity advice in here is 2 years out of date. Making the case below, and I expect to lose some of it in the comments. Pulling the figures out of the title: 2 years.…
SGN vs ERP on the same compound, same month — both cleared 97.0%. I will put the method line and the batch identifier up front because that is what makes this…
batch is the most under-discussed thing on this board — a position I have arrived at slowly and would like tested. Tested three lots over a year rather than three vials…
Asking properly rather than in a comment on somebody else’s thread: how do you actually verify Janoshik. On inter-lab disagreement, which generates more heat here than…
reading below spec threads from 2024 and half of it aged badly. Not a hot take, just something I have not seen said plainly here. CPC BPC, batch matched the paperwork,…
the batch advice in here is 3 years out of date. It is the sort of thing everyone half-believes and nobody writes down. The relevant figures are 3 years, and they come…
Question in the title, detail here: do test results actually matter or is it forum lore at this point. Have now spent more on testing than on some of the orders. No…
Vendor-level purity averages over time, built from independent results rather than vendor claims. Transparent methodology, open dataset.
Browse resultsSlightly 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…
The claim in the title is exactly the claim I am making: split one vial across VendorInvestigate and PeptideMeter — 99.1% and 96.8%. Nothing implied beyond it. Numbers,…
how much of what we believe about purity actually comes from PeptideMeter threads — that is what I am asking, and I have already read the wiki twice. First result I…
the below spec advice in here is 2 years out of date. I have gone back and forth on this for months. The numbers the title promised, since a headline without them is…
Janoshik is not what most of this community thinks it is. If you already knew this, the post is not for you and you can scroll on. FGP BPC, batch matched the paperwork,…
three years of Janoshik threads, summarised so you do not have to read them — a position I have arrived at slowly and would like tested. Tested three lots over a year…
Thinking out loud about this: test results — 20 things I got wrong before I got it right. First result I ever posted here got asked for the batch number and the claim.…
help me understand PeptideMeter, I have read the wiki twice — that is what I am asking, and I have already read the wiki twice. Date of analysis anchors the result to a…
the Janoshik thing finally clicked for me and I want to write it down, and I am aware this is a minority view on this board. Fourth lot from the same supplier in the…
Trying to get a straight answer on this: below spec — what am I missing here. Chain of custody is why member-funded testing is worth more than a supplied certificate:…
A running record of independent test results people paid for themselves. Every post follows the same shape: vendor, product, batch, testing service, method, and the number. Good results and bad results are equally welcome and get equal scrutiny.
