@G.Patton I synthesis amphetamine sulfate by Al/Hg method. But it has no effect.
I made some p2np. When synthesis is done I raised ph to 11. Separated the free base. Evaporated the solvent. Dissolve free base in pure acetone and started to add sulfuric acid. After filtering the amp. I leted it dry. It became a little pink. I think that was because of too much acid. Ph was about 5. Yield was about 14gr.
So I Dissolved the amp sulfate in water and add naoh solution until ph was 11. Separated the free base and start to add sulfuric acid again. After drying This time it became a little yellow. I think that was because of high ph. Ph was around 6.5. So I Dissolved in acetone again. Added a little more sulforic acid. To ph 5. This time I got white solid.
I tried a little by nose. No effect. Dissolved a little in water and drank. No effect.
I took a amp strip test. It was positive.
What is the issue.? Why I can't successfuly synthesis anything

First pic is p2np
