Could some of you answer WHY i sometimes get negative effects from some of the following stacks?
1 scoop by itself - sometimes great, most of the time very anxious and nervous feeling.
1 scoop FXT with 25mg ephedrine- ALWAYS amazing, clear focus, no jitters, no nervous feeling.
1 scoop FXT, 100mg demi(phenylpiracetam), 20mg - amazing focus, but almost too much like my brain hurt, and had a "hangover" type feeling after.(with DAA no hangover)
750mg , 200 mg Sulbutiamine, 600mg , 200mg caffeine - Just feel GOOD, happy, motivated, retain alot more, seem to speak with more confidence, concentration is good.
What is strange to me is how FXT can cause me to feel so anxious without ephedrine, but with it I am calm and focused.
Was hoping some of you could tell me WHY this is, not that it matters but it interests me. Maybe I have low dopamine levels or something??
