what strength are they anyway? just 5mg oral puts a real spring in my step (without tolerance) never done any stims IV, but I'm sure shooting good coke would be better than crushed dexy.

Dex are useful for those days when you can't be fucked. Did tan a load off over the summer esp at Bangface which was fun, but generally just buy them for when I have to get shit done or stay awake
