High-throughput bioaffinity mass spectrometry for screening and identification of designer anabolic steroids in dietary supplements.
Aqai P1, Cevik E, Gerssen A, Haasnoot W, Nielen MW.
Author information

Abstract
A generic high-throughput bioaffinity liquid chromatography-mass spectrometry (BioMS) approach was developed and applied for the screening and identification of known and unknown recombinant human sex hormone-binding globulin (rhSHBG)-binding designer steroids in dietary supplements. For screening, a semi-automated competitive inhibition binding assay was combined with fast ultrahigh-performance-LC-electrospray ionization-triple-quadrupole-MS (UPLC-QqQ-MS). 17β-Testosterone-D3 was used as the stable isotope label of which the binding to rhSHBG-coated paramagnetic microbeads was inhibited by any other binding (designer) steroid. The assay was performed in a 96-well plate and combined with the fast LC-MS, 96 measurements could be performed within 4 h. The concentration-dependent inhibition of the label by steroids in buffer and dietary supplements was demonstrated. Following an adjusted bioaffinity isolation procedure, suspect extracts were injected into a chip-UPLC(NanoTile)-Q-time-of-flight-MS system for full-scan accurate mass identification. Next to known steroids, 1-testosterone was identified in three of the supplements studied and the designer steroid tetrahydrogestrinone was identified in a spiked supplement. The generic steroid-binding assay can be used for high-throughput screening of androgens, estrogens, and gestagens in dietary supplements to fight doping. When combined with chip-UPLC-MS, it is a powerful tool for early warning of unknown emerging rhSHBG bioactive designer steroids in dietary supplements. Any one able to get this one

I think I can get it ordered. I'll stop by the library today hopefully.

HenryV, it is my personal view that It is fruitless to expect finding something useful in that specific german article.

Nada.

No traces for the mega-steroid you have been searching for, dear henryv.. 

The series in your blog will be incomplete without the mega-steroid you are after. 

Just saying.

 

- Says who?

 

- Just a humble, steroid, yoda.
