When it comes to pre-workouts, USP Labs Jack3d is one of the few products that have survived the years. Where most pre-workouts have faded into oblivion and completely bit the dust, JACK3D lives on ... and now, it has undergone a complete evolutionary change, which is nothing less than revolutionary.


Today is the day of day and age of science and clinical dosages backed by scientific research. Much time and effort has been invested in testing sports nutrition ingredients as scientists hunt for that extra metabolic edge to drive us towards new levels of performance.


Jacked delivers 6 grams of L-Citrulline. At this dosage, it has been shown to support blood flow to muscle tissue and boost VO2 (maximal oxygen uptake) 1,2. This will deliver benefits for both aerobic and anaerobic exercise.  At an 8 grams dosage, Citrulline has been shown to boost bench press volume by 53%, reduce muscle soreness by 40% and boost leg press volume by 21% 3,4,5. This is impressive to say the least.


Jack3d Pre-Workout also contains arginine nitrate, which delivers 2 interesting nutrients. Arginine supports nitric oxide synthesis, just as citrulline does, while nitrate can be utilised for a seconday pathway, again for the production of nitric oxide. This makes for comprehensive NO support.


Jack3d delivers an epic 375mg caffeine, so hold on to your socks. It also contains 3.2 grams of beta-alanine to get you tingling, Vitamin C and Teacrine. Teacine helps to improve dopamine signalling in the brain, which improves mood 5.


USP Labs Jacked Pre-Workout is certainly a ripper. If you're not experienced with strong stimulant pre-workouts, it would be best to try a 1/4 or 1/2 dosage before lunch. If you're a veteran of pre supplementation, get ready for a cracker session with loads of volume.
