Sorry, but baking it at 250 degress will kill less bacteria than the ba will. It is a waste of time, and it WILL break down some of the compound. It your process is performed in a sanitary maner, all one needs is the ba and a 45 micron filter to make a very clean product. I make tren regularly. I've injected myself hundreds of times with homemade tren, and have never had an abcess. Also I can draw it through a 29 guage insulin needle (in use tren strictly for site injections).
