what you don't understand? that raw manufacturer can create pure product if they want and they care?

That a "random" sample used for this particular work would test as clean as the euro pharmacopeia ref standard. As I said, not a hint of anything besides side product. No free hormone. No precursor. Nothing. Look at the GCMS raw data.
IMO: All the data we have thus far indicates HPLC overestimates purity of Test ester raws with -ene impurities due to the inability of the HPLC method to resolve the respective peaks.
See posts #219 and 220. Combined with data shared above by Jano today (minimal side product formation in GC), the picture seems very clear to me.
Would be simple to demonstrate with testosterone impurity (-ene) reference standard mixed with test ester ref standard at various ratios. Then shoot onto HPLC.

We'we had exactly two test e raw samples in last week and the other was 30% purity, so I figured it wouldn't be quite representative.
And I didn't feel like scouring the archives.
Will run the CRM through HPLC tomorrow if we have the time.

Thanks for the follow up. Sorry I am confused.
Just need the HPLC raw data for this, no? All that is shown in the raw data file is the GCMS data.
If someone is interested in all of this detail, I'll split the CRM for the testosterone -ene impurity now that Jano purchased this TE reference standard (CRM). That should get to the bottom of this issue.

Was the test C raw sample with more shit in it? Like ditotrestolone or something like that..I would have been more interested in seeing the pharmacopeia standards of test C ran against those test C RAWS, but my knowledge about all these stuff is very very poor so probably just talking shit

Test E or Test C. Either one proves the same point. He is doing the CRM for Test E which is great.
See my extensive comments above. The Test C and Test E raw I had my collaborator send in appears to have been significantly containminated with impurity the HPLC may show as Test C / Test E. That's what we ate trying to trying to figure out (Project 3).
