I have been on vyvanse (lisdexamfetamine) 6o and dexedrine 10 for 7 months, efect is bnot as desired as bfar as focus, is desoxyn better, how an i obtain?

Desoxyn (methamphetamine): Desoxyn is the "thermonuclear bomb" of adhd treatment. It is literally fda approved, pharmaceutical grade methamphetamine. I have personally used it in only two patients that failed everything else - and it worked great. I think i'm reading that the effects you were getting are fading. You might try adding l-tyrosine 500 - 1000 mg 2 - 3 times per day on empty stomach to boost their effects.
