I'll Pump You Up







USP Labs struck pre-workout gold with its first pre-workout supplement – Jack3d. The old Jack3d pre-workout formula was one of the strongest and highest rated pre-workout supplements on the market but it contained the controversial stimulant 1-3 Dim. USP labs have now constructed a formula that puts more emphasis on the muscle pump than the “energy” profile. Let’s dive in and take a look and see how it stacks up vs its competition.


Taste and Mixability:

When it comes to taste and mixability – Jack3d Micro is one of the better pre-workouts. Jack3d Micro comes in four delicious flavors: Blue Raspberry, Fruit Punch, Lemon Lime and Sour Cherry. You can’t go wrong with any of the four flavors and most people enjoy them all. The Blue Raspberry flavor is consistently the top rated flavor – but all of them are delicious. You will be able to mix Jack3d Micro extremely easily, using nothing more than just a shaker or water bottle.


USP labs Jack3d Micro has a very clean and focused energy profile, and best of all it costs well under $1 per serving. This is an incredible deal as some of the top pre-workout powders will cost much more than $1 per serving. When it comes to price per serving, Jack3d is without doubt one of the better value pre-workout supplements. While Jack3d lacks the stimulants and large amounts of caffeine, you are getting a highly effective pump and performance ingredient profile that will help your workouts tremendously.

The best price we found for 146g tub (40 servings) was $27.95 at IllPumpYouUp.com.



When it comes to muscle pumps you can’t top Jack3d Micro. However, when it comes to the huge burst of energy, Jack3d Micro will disappoint you. Since Jack3d Micro does not contain strong stimulants, Yohimbe, Beta alanine and large amounts of caffeine you will not have the giant surge of energy. The original Jack3d formula is much stronger when it comes to the energy profile – but we prefer the Jack3d Micro when it comes to huge muscle building pumps. Jack3d Micro contains L-Citrulline, Arginine, and Agmatine Sulfate for giant muscle pumps that will make you feel like a beast!


Side Effects:

This pre-workout contains very few side effects since it does not contain strong stimulants and/or Beta alanine. The only potential side effect is slight dizziness if you are highly sensitive to caffeine.

Jack3d Micro – Our Verdict:

While USP Labs Jack3d Micro may not be the best pre-workout choice for someone looking for massive amounts of energy – it is still a really effective ingredient profile and is perfect for beginners. If you are really sensitive to caffeine and stimulants and are looking for a huge muscle pump without any potential side effects – Jack3d Micro is the perfect choice. Jack3d micro contains a great ingredient profile for muscle pumps with its high dosage of Agmatine Sulfate and Arginine and only contains 125 MG of caffeine per serving. At less than $1 per serving – Jack3d Micro is a low cost investment for your pre-workout supplement.
