Next Level Pumps

NUCLEAR PUMP is loaded with premium ingredients and massive dosages for massive pumps, for increase in focus and strength!


Nuclear pump is more than just a "pump" product but a complete and comprehensive stim free pre workout that is extremely versatile. A stimulant free pre workout is a great option for those wanting everything in a pre workout without the accelerated heart rate and side effects of jitters and anxiety which is a common occurrence in higher stimmed pre workouts. This could be particularly useful for those wanting to cycle off stims to give there adrenals a break or even using it in prep or a cutting phase where fat burners are used as most traditional fat burners do not contain anything for pump and performance.


There is nothing like it! NUCLEAR PUMP is here to take your training sessions to the next level!

Best pump on the market

Let's start with the reason why we're here, the pumps. I absolutely love this during my chest & tricep, back & bicep days. The pump is beyond amazing. Drink enough water and you'll never want to leave the gym. And now to the focus. Many supplement companies will claim their supplements have "laser focus" but I have tried a few and they were okay. This stuff packs 700mg of Alpha GPC! It's all about quality when you read the label and understand what the ingredients do. Thank you for making is tasty asf, too!

The best pump product ever made... Period.

The pumps are just out of this world!! I got those crazy Rad140 like pumps but I'm in the fourth week of my PCT!! The performance is also amazing and did I say that it contains 700 mg of AlphaGPC. Yes you've read that correctly!! A must have in your arsenal.

Best pre in the world

Initially tried pump from a sample and haven’t looked back. Pre full of stims such as beta don’t agree with me pump has none of that, it tastes amazing and can be taken any time of day or night with no awful crash, I will continue to buy pump for some awesome stim free pumps

Nuclear pump is one of the best pumps ive used on the market, the taste of lemon is incredible and so is the pineapple. Using the Intra alos and recovery is improved along with performance.

The best stim free.... Ever.

Absolutely bonkers. I've been using supplements for ages, like from my day of birth (not really, but catch my drift lol) anywho, this is loaded to the brim with epic ingredients that work cohesively to bring you animalistic pumps, breathtaking focus, mental clarity, performance and strength. Honestly this is more than what I bargained for. This is so versatile too, throw a scoop into your pre workout and you will thank me! The flavor is also impeccable considering the ingredients they had to mask and the extreme dosages. This is a game changer and literally one of the best products I've ever used. Do yourself a favor and buy it!!!

Nuclear pump truly is the best pump product in canada

Had great experience using this product. For someone who has used all of the best pump products in the game and knows their supplements/ingredients inside and out, this lived up to the hype and is able to compete with the best out there such as volugen, king of pumps and infl8. An extremely strong ingredient panel and what i would likely call the best product on the market in the "stimulant free pump and focus" category. The guys at peak performance labs truly nailed it and the customer service was also awesome.

Skin splitting pumps

if you’re looking for a pump products that works and isn’t bullshit, this the product to check out. I review supplements as a hobby and I’m proud to say this product had my muscles so pumped and feeling so full , I thought my arms grew an inch just from taking it. I had forearm pumps that were unreal. Peak Performance Labs has definitely put a solid product out, that I will continue to support and take. -Suppzondeck
