My homemade pre-workout is a 'non-stimulant' stimulant, since I can't (shouldn't) use stims.
Contains:
Taurine
AAKG
Glutamine
Creatine
D-Maleate
Citrulline
Glucuronolactone
DMAE
Tyrosine
Beta Alanine
Phosphatidyl Serine
Grapeseed
Sometimes optionally add caffeine-y stims:
Green Tea
Guarana
Caffeine
It's really pretty effective even without any caffeine stuff.
