So I've been experimenting with Spike Shooter again, and it seems to be working for me a bit better now. I've had a couple of amped up trainer rides after having a little, although I'm still working on the proper dosage. One day last week I drank a whole can of it then decided it'd be a good idea to do the Incline, TWICE. Then I had some extra energy when I got home, so I rode the rollers for a while, and later on I thought it'd be good to go lift weights too... I was sore for 4 days. I think a full can might be a little "too much" energy. I don't see how this stuff is legal.
