USPLabs is perhaps one of the most celebrated companies in the nutritional and sporting supplement arena. And it’s due in large part to their original flagship product ‘Jack3d’. However, unless you’ve been living under a rock for the past few months, you would already know that a certain ingredient (DMAA or 1,3 Dimethylamine) in USPLabs Jack3d was recently  banned for sale, use and distribution in several countries including Canada, New Zealand and Australia.

As soon as USPLabs got wind of this impending ban, their R&D team went to work to develop a brand new product to replace Jack3d. The new product called Jack3d Micro has finally arrived and is in our warehouse ready for dispatch. So we have put this review together for you to read before making your purchase of one of the years most hotly anticipated pre-workout supplements.

Jack3d Micro Ingredients

First we will start with the ingredients. In order, the ingredients in Jack3d Micro are as follows:

  • L-Citrulline
  • Arginine Nitrate
  • Agmatine Sulfate
  • Caffeine (151 mg per serve)
  • Norcoline (Norcoclaurine Hydrochloride)
  • Grape Seed Extract
  • 3,4-Dihydroxycinnamic Acid
  • Food acids (300, 330)
  • Flavours
  • Silicon dioxide (551)
  • Sweeteners (955, 950)
  • Vegetable Stearate

Jack3d Micro Ingredient Analysis

Of the ingredients above, the major ones that stick out are NorcolineTM and 3,4-dihydroxycinnamic acid. If you’re anything like me, you might not be as familiar with these ingredients compared to the others in Jack3d Micro.


NorcolineTM is the brand name assigned to a compound called norcoclaurine hydrochloride. This compound is also referred to as higenamine in the scientific literature. Higenamine is an active ingredient of Aconite root in Chinese herbal medicine, which has been shown to possess cardiac stimulatory and vasodilatory properties. So in other words, it helps to get your blood flowing.

3,4-Dihydroxycinnamic acid

3,4-dihydroxycinnamic acid (3,4-DA) is a compound produced by the metabolism of chlorogenic acid, which is one of the major antioxidants found in various foods, with coffee being of particular note. As an example, consumption of about 400 mL of coffee results in the ingestion of 0.5-1.0 g of chlorogenic acid and 250-500 mg of 3,4-DA per day. USPLabs stipulate on their label that the caffeine content per serve of Jack3d Micro is 151mg, and with 3,4-DA listed several ingredients after caffeine, it’s probably present somewhere between 50-100mg per serve. Studies in animal models have found that administration of 3,4-DA resulted in higher exercise tolerance and reduced blood lactate. Therefore, 3,4-DA may be able to reduce the fatigue associated with exercise and some think it plays an important role in mediating coffee’s beneficial effects on performance.

Jack3d Micro Dosage

The serving size of Jack3d is 3.63 grams which according to USPLabs equates to 1 level scoop of the powder. One of the more intriguing aspects of the directions on the label is the amount of water, namely, 472 ml, that users are advised to mix with each scoop. That's almost 100 ml more than your average soda can. We did a little experiment in the office to try and determine why USPLabs advise such a high amount of water. We made a normal batch using approximately 470 ml with 1 scoop and another using roughly 115 ml with 1 scoop, just to see the difference in taste. As it turns out, mixing 1 scoop with 470 ml resulted in a rather pleasant taste that was easy to drink. This was in contrast with the concentrated mix, which was much more harsh on the palete. The major drawback however with the normal amount of water was simply that drinking 470 ml in one sitting tends to make one's stomach distended. If drinking this amount of fluid in one sitting is too much for some, then a more concentrated mix is the only alternative.

Jack3d Micro Flavours

We tested the old classic 'fruit punch' flavour and found it to be quite pleasant and easy to drink. Unlike other pre-workouts, there is no real bad aftertaste or harsh chemical taste. So all-in-all, the taste is a big winner with this product. Jack3d Micro also comes in lemon/lime.

Jack3d Micro Mixability

As you might of guessed, Jack3d mixes very well, especially with the large volume of water relative to the size of the dose. A quick shake is all thats needed to mix and 'floaty' bits are hardly visible.

Jack3d Micro Effects

As is common with any supplement, effects vary from individual to individual. Staff at our office exihibited both positive and neutral effects. What's for certain however, is that you don't get the crash and burn effect that was typical of original Jack3d due to its DMAA content. Generally speaking, users can expect a clean gentle energy hit and pump, without jitters.

So at the end of the day, would we recommend you try the new Jack3d Micro? Absolutely! With a bunch of new innovative ingredients backed by both traditional  and peer-reviewed science as well as a great taste; the new Jack3d Micro is perfect for the individual looking for a fresh change to their pre-workout supplement.
