I ordered Redblast and PureCEE through Anafit and started on it last week. I don't know if it's coincidence but since I've started, I had massive headaches when working out and running. A little background: Started @ 5'7" - 162lbs Currently 148lbs Quit smoking and cut down drinking to one day a week on April 1st, 2007. Smoked since high school, I'm 34. Started running 3 days a week to help remind me how bad I needed to quit smoking. It started slow, but after about 3 weeks in, I was able to run 3 miles in 30 minutes w/o feeling like I was gonna die. (I'm down to 3 miles in under 24 minutes these days). Also, during this, diet change. Lots of protein, low carbs, lots of veggies, (i never really had a sweet tooth) no soda or cookies and shit. Started on a 5x5 lifting routine + 2 days cardio (running). Squats, deadlifts, bench, rows, pullups, goodmornings. Some other stuff. Didn't target anything in particular. About a month ago, switched to a more targeted routine. 12,10,8,6,12 reps. 2 days upper, one day lower and reverse the next week. 3 days cardio (mixing some days with HiiT). Really digging this routine. It's so much quicker than 5x5 and i'm gettin some definition Anyway, fast forward to last week. Took the recommended dosage of redblast on lifting days and recommended dosage of pureCEE on off(cardio) days. Somehow I don't think it's coincidental that I got MASSIVE headaches while lifting and running. Almost unbearable. I made it through my routines, but it was tough. I don't have them when I'm not doing anything physical. I get them right at the end of a set or when I'm really starting to strain. Just pounding headaches. After workout, it takes about an hour to go away. The last time I took em was Friday, thinking that yesterday, during lifting, I'd be headache free . . . Well, I had em again. I guess my questions are, how long does this stuff stay in your system? Is headaches a side effect? Is it completely coincidence? I haven't gotten these headaches at all in the past 6 months and there hasn't been any major change in diet or anything. Need help. Sorry if this is noobert stuff. Any help would be appreciated though.
