Although I am fairly new to weightlifting and pre workout supplements, with most stimulants in the past I've experienced bad crashes. Jack3d is the first one that I do not have much of a crash afterwards. I've tried every stimulant under the sun for ADHD and with all of them I experienced intense crashes. Do some people start to experience some adrenal fatigue after taking Jack3d for a few months? How long do you recommend taking it before giving your body a break?
Thanks for the feedback. Depending on one's stim tolerance, and one's response to Jack3d, one could use Jack3d for 8 - 12 weeks and take a break of 2 - 3 weeks. There is no
one-for-all rule here, though. It might be time to cycle Jack3d, or any other supplement for that matter, when the response curve drops (that is, when one does not respond anymore to it, or when one needs higher and higher doses to elicit the same response as at the beginning of the cycle).
