I don't understand.

Either

- the HPLC test of the raws (90% purity) is correct

Or

- The GCMS test of the oil (no impurities corresponding to the 10% of the weight of the raws detected) is correct

I do not see how both tests could be correct. Unless the impurity detected in the HPLC somehow disappeared in the brewing process (like water evaporating).

Help a brotha out here

They knew what the purity was and compensated for it in the brewing process, like some of the more detail oriented homebrewers do. I can't imagine any commercial producer brewing blind on the hopes the raws are the same purity level they were months ago.

Now one could question why that 90% raws test result wasn't the one attached to the price list.....perhaps an oversight. Hopefully the most up to date pre-new oils brewing raws test results will all be attached to the pricelist.

Frankly, even relatively poor results won't impact sales much. Not many places to go for raws atm.

Oils were made before the test.
No way to know it was 90%.
Usually test raws are all assumed 99%
Only deca and EQ are assumed 90%
 
The finished oil was brewed earlier, before his test, assuming the purity is 99%

Even if they compensated in the brewing by using more of the raw powder than would be prescribed with purer raws, then the GCMS results of the oil should still show an impurity that is roughly 10% of the AUC of the Testosterone Decanoate.

And on second thought, the 7β‐Acetoxyandrost‐4,6‐dien‐3‐one may well be the corresponding impurity. Since 2.94 % / (2.94 % + 25.25% ) = 10.4%, which is in the same ballpark as the impurity percentage detected with the HPLC.

According to GPT o1:
7β‐Acetoxyandrost‐4,6‐dien‐3‐one is a steroid derivative from the androst-4,6-diene family. Its structure includes an acetoxy (–OCOCH₃) group at the 7β position on the steroid backbone. Compounds in this family are often synthetic analogs or intermediates related to anabolic–androgenic steroids, though the specific properties and uses can vary depending on functional groups and substitution patterns.

7β‐Acetoxyandrost‐4,6‐dien‐3‐one can appear as a side product (impurity) in the synthesis of steroid esters—especially if reagents such as acetic anhydride or other acetyl donors are involved at any stage, or if partial oxidation/rearrangement occurs. Even small process variations (e.g., temperature, pH, reaction time, or reagent purity) can lead to minor structural changes in the steroid ring system, resulting in compounds like 7β‐Acetoxyandrost‐4,6‐dien‐3‐one appearing in the final product.

So, yes: it’s plausible that 7β‐Acetoxyandrost‐4,6‐dien‐3‐one is an impurity formed during the synthesis of Testosterone Decanoate.

No published pharmacokinetic data: To date, there are no peer-reviewed studies detailing how 7β‐Acetoxyandrost‐4,6‐dien‐3‐one is absorbed, distributed, metabolized, or excreted in humans (or in animals).

That is exactly why AAS users want high-purity raws. The more pure the raw, the lower the amount of mystery compounds we inject, with their unknown health effects.

Well done. Ballpark same ionization and volatility. Hence my comment about testing raws by GCMS. Sample doesn't get diluted with other stuff having vastly different volatility and ionization with MS.

If only we had an independent HPLC test on the raw. Haha.

Always good to have two independent analytical methods give you the same answer. Pro tip, lol.
