Did i read it wrong?
29.22 Benzyl Benzoate
23.99 (E)-9-Octadecenoic acid ethyl ester
MESO-Rx
Anabolic Steroids
GCMS and HPLC -- any relationship?

You are clarifying the EO comes off as "ethyl oleate" on GCMS not the ethyl ester hit? Am I understanding correctly?
FML. Cue up the mass spectra, lol.
Area % in GCMS does not equal mass or volume % in the sample.Did i read it wrong?

Two different compounds.

Isn't BA and BB semi qualitative?
For EO, even if it's the same stereoisomers?
So what is this then..(E)-9-Octadecenoic acid ethyl ester

Remember trans fats, like Crisco ? (partially hydrogenated vegetable oil)
The "E" version is the trans version of ethyl oleate so technically is called ethyl elaidate (so EE not EO lol)
Ethyl oleate would be written the same but start with a Z instead of an E
There are a few similar looking molecules in this report that probably contribute similar properties to the finished oil, so maybe "EO" was never really just "EO" all along, but rather a somewhat unrefined mixture of stuff that's kinda like EO

Was I close ? xD
Excellent correlation though as we have shown above. Same for BA and BB.
So they are stereoisomers. One added to oil, other byproduct of GC temp? From carrier oil?
Thanks.

I'm just curious what oil it is now.
It looks like a mix of some sort, not entirely MCT.

So i guess that it may have always been true that..the Chinese isn't using EO.
Except all of them except Q is using pure MCT.
Eh no..this has EO..

Come to think of it, it was stupid to think any oils are 100% pure or identical batch-to-batch
Of course EO isn't 100% EO just like how every batch of GSO or MCT will differ slightly in fatty acid composition
Maybe the Miglyol oils come close since they're so highly refined, but probably still not 100%

Yes this is true. However based off the data we have, they are roughly the same, for both the domestic and china oils, just a variant in %

Looks like a mix of MCT & EO
Assuming (which I think correctly) EO is not one molecule but rather a blend of structurally similar molecules (probably the same with all oils)

Injecting trans fat doesn't sound..any bit good.
However I'm just puzzled why it shows up as Ethyl oleate in WWB but not in PUCA or SSA. The other components do look the same.
If we go off this, then SSA and PUCA are using MCT + some other oil and wwb is using MCT + EO + some other oil.
We also have the assumption that almost all these oils come from stromusc, a single factory.

BA/BB was a pretty cheap add-on test at $30. Might come up with a similar correlation with enough data.

I don't know if this answers your question (or any question), but EO can convert into EE with heat
It could be a matter of temperature during shipping
Correction: EO is likely more fluid than EE so better at making a finished product flow like water
Dose/poison but yeah
Yes, eyeballing the data I can tell you the correlation with those is striking as well. Thank you.
Wait till you see the GCMS / HPLC AAS correlation with the tren experiment data points added on. Really nice.

The more data we get the more i feel i should just pay for overpriced dubious quality raws and just use my mig840 for everything..
it was supposed to be TP 200, but tested as 110mg

Makes sense. I will update the model, gimme a sec. Got a feeling we'll hit 30 samples by month end. The predictions so far is pretty dam accurate.
