      I wrote that thread a couple years ago when I was bored. Unless you have access to a well equipped lab and some real training, most of those syntheses are going to be too difficult. There are some easy ones but you still have to have access to chemical reagents and some way of either mechanically or magnetically stirring your reaction solution.

      Example: Any of the prohormones with double bonds in the 1 or 4 positions (or both) can be easily oxidized to the corresponding AAS by stirring it in dichloromethane solution with 5x by weight of MnO2 for 24 hours. Filtering off the MnO2 and evaporating the solvent will give good to excellent yields of already fairly pure material. The most likely contamenent is the starting PH (if your MnO2 was not active enough).

      Those types of syntheses are the only ones I would feel comfortable telling untrained people to do as they represent a minimum risk (no especially hazardous reagents). If you screw it up, the worst you can do is inject yourself with something containing some percentage of PH; no big deal.

        I can't get my hands on any Mno2 or chloroform/dichlormethane.
        Any suggestions?

          Nope, sorry. Other oxidations generally require reagents even harder to come by (and more hazerdous) for the general public than MnO2 and require some purification afterward to remove toxic reagents or byproducts.
