Superpump- was ok, but got tolerant to it too quickly(2 weeks)
1MR- was pretty good stim, VERY intense and i pushed more legit, but CRASHED HARD after everytime.
Blast Powder or whatever its called - sucked. made me gag while throatting it down.
NO Xplode- for ppl who have never tried stims before.
N2KTS - tastes the best so far, and i dont have any crash after. the effects are satisfactory. prolly the best so far.
