I took my sample on a empty stomach, and felt it hit me within minutes. I only did arms today, but on every single rep I had the energy to push until my muscles literally couldn't go anymore. Then had energy for hours after my workout as well. There must be some sort of stimulant in it that I have 0 tolerance to (I am somewhat of a stim junkie). I would describe it similar to the first time I took something with 1-3 dimeth, except it lasted for hours. I cant wait to use my other sample on leg day and see how badly I can wreck my legs.
Mixability: about the same as Jack3d, a few floaties on the bottom
Taste: I am not a big fan of blue raspberry or w/e flavor it was.
Focus: about the same as taking ephedrine for the first time lol
Strength: I'm sure it would have been a lot more if I hadnt taken it on a empty stomach, I could feel I had used up all my stored energy, but still wanted to keep going.
Overall: extremely impressed, just didn't really like the flavor
