Testosterone

Hi I'm looking for references or places to look for information pertaining to the Idenification process of testosterone and it's various esters.
Any help would be appreciated!
Cheers

GC/MS works quite well. I guess that immunoassay would do the trick too.
Well, that's how the professionals would do it. I think that, if all you want is a "how do they do this?" guide, then any textbook on organic analysis would help you.
I seem to remember that there are a couple of compounds called Girrard's reagents that are used in extracting ketosteroids.

In terms of home labs, I think that you are down to measuring melting points (153-155C); specific optical rotation (115.6 deg); or bioassay.
If all else fails, you can inject it and see what happens; IIRC one of the effects is shrinkage of the testes.
Unfortunately, some things really are not in the remit of most home experimenters.

Thanks for the quick reply.

How about using tlc with rough Rf values for a given solvent.

did they use ms/gc in the 40/50s?
or xray crystalography?

what I mean is they must have Identified it low tech, this may be reproducable at home?

Yes, they used low tech. They used bioassay- feed it (or inject it into) rats.
I don't think that you will repeat their data.

Biologicly it's produced like this
