Jack3d Micro by USPlabs:

Reinventing the PreWorkout Revolution!

Have you met the New Jack3d Micro by USPlabs? Researched and formulated by the makers of the original Jack3d that revolutionized the preworkout category…this newly revamped formula offers a completely different user experience to shatter max PR's, skyrocketing you past stubborn plateaus. In one word Jack3d Micro is "EPIC".

What's under the hood in Jack3d Micro?

The Micro Technology is at the core of the delivery and sustainability of the new Jack3d Micro. The most exclusive ingredients with specific targets to bring maximum results in minimum dosing. This compound technology packs a powerful punch!

Train like you've never trained before…

With Jack3d Micro, your body is primed to ignite into the most fierce and relentless workout leaving your muscles so engorged, so supercharged it'll blow your mind!

Once you start moving serious weight and your physique begins to change, one of two things will happen:

  • They will aim to be near you (groupies)
  • They will aim to try and take you down (haters)

The great ones thrive on this…and they also have their “secret weapons” to ensure they dominate and turn heads every time they set foot in the gym… It may sound crazy, but not everyone can handle this…CAN YOU?

Jack3d Micro Pump and Performance Sent from the Heavens!

You’ve NEVER experienced anything like the Tri-Pump System…Your workout may have ended hours ago, but your pump sure hasn’t!

Jack3d Micro Ingredients


This particular compound is an amino acid that has been shown to potentially improve exercise performance and reduce fatigue.

In addition, it serves as a superior way to increase arginine levels in the body, thereby providing a substantial amount of substrate for NO formation through eNOS…

This increase in NO is extremely important because combined with all of the other mechanisms through which the product can increase its formation…

This is important because NO influences glucose uptake, the contractile function of skeletal muscle, blood flow to your muscle and last but certainly not least, it influences muscle repair through satellite cell activation and the release of myotrophic factors!

Agmatine Sulfate

Unless you’ve been living under a rock, you know Agmatine is the “hot, hot, hot” ingredient these days!

With that said, it’s VERY expensive and tough to source quality material…

You’ll see a lot of “sprinkling” of agmatine in products in the near future. That’s certainly not the case with Test Powder and it’s not the case with Jack3d Micro either…

“Micro” contains a precise amount in conjunction with the rest of the formulation for gym domination!

Arginine Nitrate

This particular compound utilizes two major pathways to generate nitric oxide (NO):

  • The classic arginine, which works through the classical l-arginine-NO-synthase pathway. This has shown to be a decent method to elevate NO and give you better gains in the gym and greater pumps.
  • This particular compound also yields the nitrate ion, which works through a recently discovered pathway, called the nitrate-nitrite-nitric oxide pathway. In essence, nitrate is reduced to nitrite, which is further reduced to NO.

This second pathway is also exciting because it can generate nitric oxide via several routes that are enzymatic and non-enzymatic, making this pathway, in some respects, a more reliable and better overall way to increase N.O.

Furthermore, this pathway becomes much more important and is favored over the classical pathway in conditions where oxygen levels are much lower and to some extent acidification occurs in a given tissue (e.g., anaerobic exercise such as weight lifting, sprinting, etc., where oxygen availability is lower and lactic acid is generated), allowing for vasodilation to occur and oxygen to be transported in these conditions…

By utilizing both pathways, NO levels can remain elevated regardless of the phase of the phase of activity. This increased NO and vasodilation may at least be partially responsible for a potential improvement of exercise efficiency by reducing the amount of oxygen and energy needed in the form of ATP and phosphocreatine during exercise and muscle contraction…

In short, it may allow more resistance to fatigue and squeeze out a little more during workouts…

Though, this isn’t just hype; in fact, a recently published study found that nitrate can increase force production in fast-twitch skeletal muscle in mice used as an animal model. This is further corroborated by the fact that one study in humans found that nitrate supplementation allowed for a prolonged maintenance of force production.

It’s also worth noting that this notion of nitrate increasing vasodilation and improving exercise performance isn’t just hypothetical. Several studies have surfaced recently which have demonstrated that nitrate can and does accomplish just that.

It is also interesting to note that many scientists have begun to suspect that at least some of the positive benefits seen with vegetable consumption are due to the nitrate content.

Typically, this ingredient would be taken around 90 minutes before a workout. However, as part of the Tri-Pump System, this bad boy picks up where others leave off, so you keep crushin’…

Grape Seed Extract

It’s no secret grape seed extract is considered a potent antioxidant. However, beyond that, it’s not well known that it may help you in the gym as well… Case in point, this extract may further increase the conversion of nitrite to NO, while also increasing eNOS expression and NO formation, thus helping both NO generating pathways.

As far as I’m concerned, that’s a nice “addition” to the already-impressive antioxidant factor!

3,4-dihydroxycinnamic acid

This particular compound is an antioxidative polyphenol found in a variety of foods (coffee, citrus foods, etc) and has multiple benefits. For one, it may enhance the bioavailability of the norcoclaurine in the formula, allowing for greater efficacy. It does this by inhibiting catecholamine o-methyltransferase (COMT), the enzyme that degrades the catecholamines and other related compounds responsible for the stimulant effects seen with stimulant type compounds. This can translate not only to a greater stimulant effect, but a longer lasting effect as well...

Secondly, it has also been shown to increase eNOS activity while also enhancing the formation of NO from nitrite by acting as a reducing agent. Thus, it can increase NO formation through the two main mechanisms through which NO is formed!

If this weren’t enough, it also has a CNS stimulant effect on its own. Yet, when combined with caffeine, it may actually increase the stimulant effects of caffeine as well!


The compound is found in a variety of plants, including Nandina domestica, Aconitum carmichaeli, Asarum heterotropoides, and Nelumbo nucifera. It’s known to be a beta 2-adrenoceptor agonist.

However, unlike most beta 2-adrenoceptor agonists, this compound does not cause vasoconstriction nor is it thought to increase blood pressure…

In fact, the compound acts as a vasodilator, so instead of hampering your pumps, it can actually enhance them. Essentially, you can have your cake and eat it too!


Beyond it’s well known energy boost, caffeine is thought to potentially increase force production by each motor unit in muscle, enhancing contractile force of muscle, while reducing perceived exertion.

Ascorbic acid (Vitamin C)

Everyone knows about Vitamin C and its general role as an antioxidant, but it also has other roles as well…

Vitamin C is known to play a role in maintaining NO bioactivity/bioavailability and is the reason why it is known to improve the effects of NO, whether the NO is derived from arginine or the reduction of nitrite.

Studies suggest that vitamin C can impact both major NO-generating pathways; of particular interest is that it (as a reducing agent) can also increase the amount of NO produced from nitrite while also enhancing the level of vasodilation; yet, it also plays a role in the function of eNOS by acting to recycle tetrahydrobiopterin, a cofactor for eNOS.

Jack3d Micro Reviews: What to Expect

Straight dope from the BETA Testers of Jacked Micro


  • Not stacked with any other pre workout or stimulant
  • Used as part of fasted training protocol
  • No heavy stimulant use prior to cycle
  • Used for resistance training workouts as well as anaerobic/aerobic dynamic activity (basketball)
  • No changes in dietary habits throughout the cycle


  • Flavor
  • 10/10
  • Amazing, easily the best tasting USPlabs product to date
  • Strong at any amount below 4oz per scoop – this will be no issue
  • Customers will drink this everyday simply because of the taste, in my opinion


  • 10/10
  • Pump
  • Prominent and seems to come in pulsatile fashion over four to five hours
  • The post workout pump is something that will surprise many users


  • Strength/performance from 1st workout, not placebo
  • More sustainable performance than heavier stimulant based pre-workouts on the market


  • Easily exceeding parameters of workouts in terms of time and short rest periods
  • Pump/NO effects seem to gradually increase at the 45 minute mark and beyond

Body Composition:

  • Although it has only been a few days short of two weeks, slight changes in body composition are noticeable
  • Seems to induce more perspiration…this product intrigues me


  • Quick acting, although not super hard hitting, which is preferred by many
  • Very even without a rapid increase or decrease in energy

"Very excited about this product, this will be a breath of fresh air in a very stagnant pre-workout market.  This will be a huge hit with those that realize and appreciate the markers that dictate a better workout. They will love this product.

As pre-workouts dominate sports supplements, it has introduced many to the market that outside of the stimulant aspect of the product, may not appreciate the subtleties that a product like Jack3d Micro has to offer…

Interesting that the efficacy of fat loss products and/or pre-workouts are gauged within fifteen minutes of dosing…something I still shake my head at (these are also the guys who never make any gains).

Every pre workout seems to claim strength and focus relying on higher or “stronger” stimulant blends disguising a week formula in most cases.  Jack3d Micro clearly separates itself from the fray…"

great new preworkout By: Sam

Review posted on: 2012-09-17 01:35:38 -0400

My new favorite preworkout. Works quick (15-20 for me to feel the max effects) and lasts long (at least 2-3 hours). Smooth and clean energy at the gym, I don't feel like I'm overactive or anything. My reps have increased and I'm lifting more. Best thing I like is that there is no crash AND no diarrhea/GI problems! :)

Disappointed By: Andrew

Review posted on: 2012-08-17 03:04:58 -0400

I totally agree with Eric. At the max does of 2 scoops I had no increase in energy or pump. I'm not sure why they removed 2 useful ingredients (beta alanine & creatine). The original formula was much better.

Weak By: Eric

Review posted on: 2012-08-14 13:48:05 -0400

This formula is very weak, I would not recommend this product. The original formula must have had a LOT of 1,3. At 2 scoops I don't feel much at all, no pumps, little energy.

*Tastes great.. USP is getting their flavor game on point. *Smooth and CLEAN energy... not stim'd out or tweaking. No jitters *HUGE PUMPS!! *HUGE PUMPS!!!!! *again.... HUGE PUMPS!!! I dose this at 2 scoops and it gives me skin tearing, lasting pumps.. feels incredible. *No post-workout crash.. which is essential for me since I train in the morning and actually have things to do the rest of the day.. not be dead to the world. *Tunnel vision focus.. I am able to concentrate on every muscle fiber it feels like. *Enhanced breathing... feels like my lungs have a greater capacity or my airways are more dilated.. really good breathing. *Broke several personal records already on Micro... I have one serving left at the moment of writing this review. I will definitely purchase this again and again and again. Its a great change up from all the stimulant crazy pre-workouts. Like a breath of fresh air. Winner winner chicken dinner in my book.
