Crackhead by Xcel Sports Nutrition

Looking for an extreme stimulant to get you motivated for your day or for your next gym session? Crackhead is the perfect supplement to blast your energy through the roof with an impressive list of stimulating ingredients.  You will also experience skin splitting pumps and mind piercing focus with addition of Beta Alanine and Agmatine.

Beta Alanine increases the production of carnosine which helps control the Ph levels of the muscle cells.  Lower Ph levels cause muscle fatigue so Beta Alanine will help you perform harder and longer.

Agmatine Sulfate improves nitric oxide levels and enhances focus and can provide neuropathic pain relief.

Caffeine Anhydrous, Hordenine are stimulants with mood enhancing properties.  This is the blast of energy with the happy pill effect that gives the extra umph to get you going and keep you there.

Beta-Phenylthylamine helps you feel more alert and have a greater sense of well-being and contentment.

Alpha GPC increases growth hormone in athletes and you may experience significant gains in memory,  brain energy, focus, and mental fluidity.

Alpha yohimbine included to increase exercise performance and build muscle mass, burn fat and boost weight loss, and may increase libido.

Paradoxine is your ticket for higher work output and greater fat reduction.

LeanGBB is the superior form of carnitine, which helps convert fat to fuel.

Once you have used this pre-workout you will never want to go without it. Get the most explosive workouts everyday to maximize your gains.  Crackhead Xtreme Pre-Workout is not for the faint of heart.

    I loved this pre workout so much, that I had to write a review. I never write reviews for anything, but I want people to know that this pre workout gives you amazing pumps. You feel motivated and focused while working out. You push yourself while actually feeling tired. I love this stuff!!!!!!

    Quality Pre Workout

    I have taken basically all of the strongest pre workouts on the market and this one has to be at the top. The pump and focus is great and I would highly recommend it.

    Very Good Pre-Workout

    I have tried almost every strong pre workout on the market and I came across this one and I am very pleased with the pumps and focus and intensity I get in the gym. Im 6ft 270 lbs solid and one scoop is plenty.

    Good product!

    The name scared me a bit, lol. But it’s not crazy strong… just right!

  9. Rated 2 out of 5



    This is the best preworkout ever if you want cold chills and be tingly for an hour +. Do not recommend. Only preworkout I’ve thrown away in my life

    Hands down the best pre-workout. I hate sugar laced pre-workouts. This is not that. It actually gives you focus. It doesn’t make you jittery.

    Its like heaven

    This is hands down the strongest and most intense preworkout I’ve ever used its actually stronger than the original jack3d formula. It has taken my training in bodybuilding to a whole new level of intensity and mental clarity as well. The pumps are crazy insane. I absolutely love and will purchasing after this current cycle is over

    Crazy amount of energy but lots of cold sweats might be to strong for some people

    I love Crackhead pre-workout. The sour cherry pina colada is the best. I also use a half of a scoop for energy all day at work. My favorite pre workout supplement so far.

    It’s equal to others

    Comparatively speaking. It’s ok. I do feel I have energy to do more reps. It does have kind of a funky taste. You can tell it has more caffeine than some of it’s competitor products so be aware of what day you take it. Caffeine effects everyone different. To late in the day…. Well, your probably not gonna sleep that night. I didn’t.

    Quality product

    I enjoy using this product. Only recommendation is don’t take it late at night. I used it a few times after 6pm and I was awake all night. Now using it in the morning is amazing. I’m wide awake and eager to get going. I feel it gave be a better pump then other pre workouts.

    Not your average pre workout.

    If your looking for a pre workout that will help give you energy and a better position, this is it. Not for the faint at heart. It has caffeine and could keep you awake at night if used late in the day. I never experienced any tingling as some noted. It all depends on how much you take and if your used to pre workouts or not. I recommend it!

    Great Pre Workout

    Best pre workout I’ve tried to date. Only thing that ever comes close is the old school Jack3d.

    This the only pre workout supplement that works for me. All others so far are not powerful enough.
