What is Jack3d

Jack3d is a “nitric oxide” pre-workout supplement. It boasts an ingredient profile designed to give the most focused, intense, and pumped workouts, and apparently has no unnecessary “filler” ingredients. It comes in Grape bubblegum, Lemon Lime, Raspberry Lemonade and Tropical Fruit.

What I loved about it

I train 4 days a week at 6am, so I found that 1.5 scoops around 20mins beforehand, really gave me focus and the energy I needed to get through an intense 45-60min session. It really does make a difference to your gym performance, and allows you to complete more in less time. Jack3d isn’t without its shortcomings however — that brings me to…

What I hated about it

The side effects: I have an issue with mood altering substances because, like most people, I have to face an office full of fire cracker personalities on a daily basis. I found myself often baring a short fuse, ready to snap at anyone who got in my way. The effects of this are apparently caused by the ingredient 1, 3 Dimethylamylamine. It’s known to cause irritability and intense mood swings. Maybe that’s why it was previously banned in Australia and somehow became available once again. (My fiancee in particular, noticed such dramatic mood swings when trialling Jack3d for a week, and has since stopped using anything containing large doses of caffeine or Dimethylamylamine—problem solved).

Would I use Jack3d again?

Well, I’m still using it now on my lead-up to a 33 day vacation. Combining it with leangains intermittent fasting works a treat due to its zero caloric profile. Using it again when I return will be another story as my body would probably benefit from a rest from heavy stimulants.

In conclusion

It’s definitely worth buying if you don’t have hugely negative reactions to caffeine or Dimethylamylamine. I have no doubt that you workouts will be more intense, and allow you to perform in a greater capacity. And at this price point, it’s offers superb value for money.

Note: You might want to get in quick though — I’ve heard rumours of people using it all day at festivals as a cheap ‘party drug’. This will likely ruin it for the rest of us.

Update 31st January, 2013

Apparently, Jack3d has been caught up in a death related incident in an article titled “London Marathon runner Claire Squires died after using supplement“.

    Its really a fantastic pre-workout, i have been on it for close to a month and still get great focus in the gym. I have progress from 1 scoop the first to weeks to 2 right now but i suppose you get some resistance. Still its really cheap considering how small the doses are unlike other pre-workout supplements. Can imagine people partying on this..Great review!

    Hi Clint,

    I figure this article is a little old, but I’m wondering particularly about the side effects aka mood swings. I work mostly afternoon-nights, which means that mornings are the ideal workout time for me. If I take this pre-workout in the morning (say 6-7am), do you feel (from your experience) that the mood swings would last past say 3pm? I’m a little hesitant about it…but I need that early morning burst of energy.

      I reckon you’d be definitely fine by then. I usually found that I was ‘ok’ by midday.
      The other way to tackle it, is to ‘ease in’ to the dosage and take half, see how you feel, then increase it if you need to the next time you take it.

    i was recommended this product by a colleague. initially i tried one scoop in about 8oz of water. after 30-40mins wait and then doing my workout it did nothing for me at all. a couple of days later i tried 1.5 scoops again nothing. the following day i tried 2.5 scoops, again aside from a slightly tingly sensation on the soles of my feet and hot ears nothing happened at all. i tried another 2 scoops today and felt nothing and my workout wasnt anymore intense than i was doing prior to using this. about myself, i go to the gym 4-5 times a week, workout for up to an hour with weights and cardio. i havent ever tried any other supplements. im a small in height with slim/ average body build so would of expected this product to be quite effective on me but so far i would rate it as extremely disappointing. i guess it just depends on how your body takes it.
