How many different steroids can one make from 1-test....

I know this is incredibly old thread but since I landed here I'm sure others will too. there seems to be a lot of confusion and discussion with regards to steriochemistry. Commercially, the 17 one group of androdione is reduced with lithium aluminum hydride or sodium metal in ethanol to afford androdiol which in turn is 3-OH oxidized with manganese dioxide. Alternatively you can reduce with sodium borohydride that is about 80% selective to the 17 OH over the 3. This leaves about 70-80% test base and 20-30% androdiol or unreacted androdione. Commercial syntheses don't make it to the floor if they are not efficient, the structure of the feedstocks of the molecules dictate the correct steriochemistry and the reagents the selectivity. For example some ask about test from DHEA, reduce with one of lithium aluminum hydride, sodium or sodium borohydride and upon oxidation of the 3-OH it will rearrange the double bond to 4 if the correct pH is maintained. If selenium dioxide is used to oxidize the 5 ene will rearrange to the diene as seen in methandieneone or boldenone.
The best way for prep of these is to let microorganisms do the work. Pretty much any yeast will do a good job but there are some that are very specific (names elude me). From DHEA thru to test with 100% selectivity with just feedstock and yeast nutrient. Same with androstenedione. The best way to test from androdione is a cold overnight stir with borohydride, it will leave most of the 3one alone.
When it comes to impurities what you need to understand people is that the gov't and the educational system plant into your mind the idea of if something is made outside the taxed pharma industry it will contain deadly poisons and chemical warfare agents will result from a reduction of dhea. Not the case, if you are careful and use the right materials you will get unreacted feedstock, desired product and then over reacted or improperly reacted which usually means it will lose the same"macro characteristics" of the feedstock like solubility and therefore a fractional recryst. will purify plenty. When it comes to injecting there is nothing magic either, you must remove pathogens (germs) and pyrogens (cause inflammation), so, filter thru .22micro filter.......done. Or boil and centrifuge, pipet off the top.........done.......sterile. Filter at .5 micron and add 5% benzyl alc. nothing will live. Remember the old steroid pharma preps where 5% BA in sesame usually. None of the 6 componant concoction crap is need, that is just to try to cram 40kg/ml into solution for these guys who abused test to the tune of a gram a day for ten years. Keep your shit to 50-100mg/ml and 5% ba in oil with a decent pyrogen filter out and you are good, a little BB cuts back on discomfort but you won't get dyptheria, herpes or St. Vitus dance, if you don't put it in

did the andro powders ever become completely illegal?
