First of I'd like to say thanks for those who have put this together.You all have been helping me with numerous things and I appreciate it.I managed to successfully complete a STB and fumarate conversion thanks to you guys.Now my problem is converting back to freebase.I cannot seem to find a method that is recommended.If someone can help me out it would be greatly appreciated it.Oh by the way the only chemicals I have on hand are anhydrous acetone,sodium carbonate,fumaric acid,and anhydrous magnesium sulfate.Thanks guys
