Sure, any of them can be pretty easily made from pregnenalone, estradiol or even cholesterol if you have a lab and access to chemicals. Therein lies the rub, the chemicals and reagents necessary are not things you can just go pick up at the hardware store and the equipment like glassware, magnetic stirrers/stirbars, graduated glassware, etc. are difficult to get without raising suspicians as well. I work in a synthetic lab but I would never do anything like that here. AS are not worth my job or my freedom. Not to mention, if I were caught, my boss would be legally liable as well; even though she would have had no idea what I was doing. I would never take the chance of getting someone else in legal trouble. I am just not that selfish I guess.
