i've had paranoia creep into a trip if i had been doing speed.. 

............. I could not distinguish reality from reality LOL
Amphetamine will provide energy to the trip, so yes, it will potentiate it.
The thing is that energy is often very raw and can cause a good deal of anxiety. It will also reduce your ability to sit still, relax, and submit to a powerful experience.
It's likely to provide a more physically energetic, recreational trip if it doesn't precipitate an anxiety episode and send the trip awry.

If you took amphetamines & stayed up for a length of time before taking the DOC it might have well potentiated the psychedelic effects, but that would really be more of a consequence of the sleep deprivation than the amphetamine itself.
I don't know about using amphetamines before tripping, but I've pretty much invariably found that methylone (MDMC) and mephedrone (4-MMC) potentiate the psychedelic intensity of psychedelics, when the psychedelics are taken at or after the peak of the **MC. I've found this with DPT, 2C-C, 2C-B, 2C-T-2, and 4-AcO-DMT. The circumstances have been such that sleep deprivation could not explain the potentiation in every case. My personal experience strongly suggests to me that pre-dosing with **MC stimulant/entactogens, at any rate, potentiates psychedelics psychedelically.Seemed as though the trip was way more psychedelic than normal. I know you might not like the way I put this but I tripped fawkin balls very very strong visuals so strong I could not distinguish reality from reality LOL
