Test Booster | Nitric Oxide | Libido | Strength





Stronger formula, much better taste, no clumping, even better results.
No Competition!

JP8x Hardcore is the most hardcore, results driven pre-workout available period!
I don't care how much caffeine per scoop others give you; the endurance, mental focus,
motivation, training intensity and aggression while training on JP8x Hardcore cannot
and has never been matched since its original introduction in 2009!


Strength Gains….Sick!
Mental Focus, Energy, Drive……Sick!
Motivation, Training Intensity……Sick!


J8x Hardcore is for those of you who want the hands down best results from a pre-workout/NO product/Creatine product. It is for those of you on a plan to attain a goal which would be total gym dominance.

JP8x Hardcore is for those of you who are NOT buying pre-workout drink mixes because they come in “cool blue raspberry cooler” or because you want the best results you can get for $29.95.  This is for those of you asking “Screw the BS claims and the scientific write-ups, what works the best?” 

In comes the return of JP8x Hardcore: “This is some hair on your chest, dialed-in, zoned out, get the ***** out my way, GET DIESEL OR DIE TRYIN’ type stuff.” None of that “we disclose the ingredients so it must work” formulas that look just like every other pre-workout, mega-dose caffeine per scoop BS. JP8x Hardcore IS NOT legal in Canada, Australia, or Europe. JP8x Hardcore isn’t formulated to be (use JP8x if outside the US). JP8x Hardcore IS formulated to be the hardest hitting, serving for serving pre-workout product available. This is the product that will take you back to the years of 2005-2008 when GET DIESEL was known for having the hardest hitting pre-workout products available with Ready4War powder and DIESEL FUEL capsule. You will not be disappointed if you shop based on results.  I don’t know how many longtime customers who are power-lifters and those that are “serious” about training have said, “Go back to that era where your stuff was killing the competition.” Well I listened and along with DIESEL TEST Hardcore and Pro-cycle, JP8x Hardcore is THAT type of product. 


You will hear about JP8x Hardcore. It’s up to you to decide if you’re going to be the one doing the talking or the one listening, while still using one of those run-of-the-mill chemical tasting, ultra-concentrated copy-cat la-di-dah pre-workouts.


Why the Proprietary Blends? Listen…h**l yeah there’s a proprietary blend.  Although most companies use proprietary blends to mask under dosed amounts of ingredients, GET DIESEL has been in the supplement industry since 2002 producing pre-workout/thermogenic products for over 12 years with none duplicated.  Do you know why? Proprietary Blends.  It makes no smart business sense to list the amount of every ingredient in your effective product right there on the label so everyone else can just boot-leg it line by line.  Why do you think so many pre-workouts look the same now-a-days? They are all just semi-carbon copies of their competitor’s products. You got:  Creatine HCL, Agmatine, Beta-Alanine, … same product.  

Listen…long answer short: Pringles®, Ruffles® and Miracle Whip® have one thing in common…proprietary blends.  It would  makes no good business sense if Ruffles® or Pringles® were to list the exact recipe to make their chips right there on the bag.  End of discussion.

There is JP8x Hardcore and then there are the other products.  Period! 

No need to sugar-coat it.


–Chuck Diesel, Founder GET DIESEL NUTRITION


Peligro (Danger) is on the front of this bottle for a reason! This is not your average run of the mill pre-workout product. Start with one scoop and adjust from there, it hits hard and it is intense! There is a big difference between one scoop and 1.5 scoops.


Expected results from JP8x Hardcore:

 -Increase Training Intensity
-Increase Nitric Oxide/Pumps
-Increase Explosive Power
-Increase Endurance
-Increase Strength
-Increase Mood
-Increase Motivation
-Increase Drive
-Increase Mental Focus
-Increased Mental Clarity
- Reduces Lactic Acid burn during and Post Workout
-Increased Muscle Hardness
-Faster Lean Muscle Mass Gains
-Faster Recovery


JP8x Hardcore is great used alone or stacked with DIESEL TEST Hardcore/Pro-cycle for even more powerful results! For long term strength and power gains use JP8x pre-workout and NOS ETHER powder post workout and on non-workout days.  You can also stack JP8x Hardcore with JP8x to maximize dosage taken, but not using too much JP8x Hardcore (many users WILL NOT be able to use 1.5 scoops or more of JP8x Hardcore). Search for GET DIESEL NUTRITION on YouTube for videos of how to dose and stack our products, or visit


Results may vary...with that said, these are typical results on JP8x Hardcore and real unsposored consumer feedback found online:

"After about 25-30 min I had an instant rush of energy. I was putting up about 10 more reps per set. I usually do 3 sets of 15 pullups. I was doing 3 sets of 27 on the first day of taking this stuff. Holy shit! I felt like a savage. I was running around with my head cut off. I did get the shakes in my hands and felt a bit like a tweaker but definitely did the hardest workout I have in a long time."
