Depending on what you want, No-Xplode is also good for lifting. It wakes me the hell up and gets me ready to roll in the gym, also Red Line is good too. But I shake with Red Line, so not good when I'm maxing, you know?
Unsure of the ingred's in Red Line, but I used to pound those Red Line capsules and when I ran out, buy the drink. One day I drunk one can before the gym, one can before work, then another can at lunch. I went into some perverted, dark corner in my brain I had never been in before and just felt like throwing anything at anyone. But I had been taking Red line for months before I did that, so I was able to handle it decent. I've had guys drink a whole can before that just shake and sweat like death is staring them in the face.
But, my wife can take the pills or drink it, and not even phase her.
