I'll do my best...sorry if I didn't make much sense earlier.
The info I posted in regard to is not a recipe for making some type of product that contains testosterone, methanol, ethanol, and chloroform. It is an analytical procedure that has been designed to determine whether or not testosterone and/or it's metabolites are found in a topical hair treatment (if I remember correctly).
Analytical chemistry can be divided into two parts, qualitative analysis and quantitative analysis. Qualitative answers the question "What is it?" and quantitative answers the question "How much?". For example, if you find a plastic baggie full of a white solid but don't know what it is you can do some qualitative testing to try and find out. You could smell it, taste it, snort it (kidding...LOL), test for flammability, see if it dissolves in water, etc. and then compare your results what you'd expect to observe when testing a white solid of a known identity (sugar, for example). So ir you tasted the unknown white powder and it was sweet...tasted exactly like sugar...you would have qualitatively analyzed the white powder because you answered the question "what is it?". If you wanted to know how much of the sugar was in the baggie you would do quantitative analysis. Most simple example would be to measure the amount of sugar you found inside the baggie. However, in a more complicated example (two-component mixture) the unknown white solid might really consist of both flour and sugar. Then you would have to figure out a way to separate the flour from the sugar before determining "how much" of each solid was in the bag. You could add warm water to the powder to dissolve the sugar and then filter the solution. When you filter, the sugar (which is dissolved in the water) will pass through your filter paper and the flour (which was not dissolved in the water) will not. Once you've successfully separated the two solids, you can allow the water to evaporate completely and can figure out "how much" of each solid was in the bag. You've quantitatively analyzed for sugar and flour after separating the two.
Think of this testosterone containing product as being the same as the flour-sugar mixture. Just like we knew that our unknown solid contained sugar, the person working with this product knew that it contained testosterone and they needed to separate the testosterone from the other ingredients before they could find out how much there was. The ethanol they used was just like our water and the chloroform:methanol mixture was like our filter paper. The difference is that they used the chemical properties of the methanol:chloroform mixture to "trap" one component and not the others instead of using a real physical barrier like a filter paper.
I hope this helps. If not I'll keep trying till I make some sense!
Sorry if I've been confusing.
