Pre Workout (NOS)

Potent Supplement to Increase Intensity & Drive.


$40.00 (NZD)

Pre Workout Supplement

NZ Protein's Pre Workout is a potent supplement that's formulated to increase intensity and drive during physical exercise.

This product contains a special blend of ingredients that work to maximise effectiveness by working in a 3 stage delivery matrix:

pre-workout 3 stage delivery matrix

Intensity - train for harder and longer Increase your strength so you can push harder with the effects of key ingredients proven to fuel training for maximum results.

Pump - take your training to new levels Extra fuel to increase NOS production and blood flow is key to maximise muscle contraction and support the muscle pump during training.

Repair - maximise your results Provide fuel to muscles to support lean muscle tissue repair and recovery. Feed your efforts by shuttling nitrogen to exhausted muscle cells.

What's in it?

Intensity: Beta-Alanine

Beta-alanine is a naturally occurring amino acid that is reported to significantly increase strength, lean body mass and muscular endurance by helping to manage the pH of the muscle cells.

In other words, it helps buffer the acidic buildup that can occur in muscle, which allows you to maintain your strength, speed, and power for a longer period. In essence, you may be able to train harder and longer because of it.

It is reported to be incredibly synergistic with creatine and BCAAs. Therefore, when used/stacked properly, this supplement may be an amazing tool to help you take your training to new levels, resulting in new personal records and added lean muscle.

Beta-Alanine is responsible for 'tingling' or 'itch' skin sensations that you may experience. This is called paraesthesia and lasts up to 60-90 minutes. This is the most common side effect and paraesthesia is not harmful in any way.

Intensity: Caffeine

Caffeine is a stimulant and gives a boost of energy - which increases alertness and wards off drowsiness temporarily. This means that it can help you to perform certain tasks for longer. This isn't just limited to mental tasks - it includes physical tasks as well, such as running or lifting weights.

This means ingesting caffeine may give you the energy you need to give 100% during your workout. And giving 100% in the gym means you may get the results you want more quickly.

Ingesting caffeine jumpstarts the process of lipolysis, which is when your body releases free fatty acids into the bloodstream. This occurs when your body is breaking down your fat stores to convert it into energy. In other words, caffeine boosts your metabolism slightly and helps you burn fat.

Intensity: Niacin

Niacin is vitamin B3. It's involved in nearly 60 metabolic processes related to energy production and ranks high for bodybuilders by virtue of its critical importance in providing training fuel. Niacin's most basic function is to release energy and can give you that drive if you're struggling to find the motivation and energy to train hard.

Niacin also increases vascularity as it causes blood vessels to widen which allows more blood to flow through them.

Pump: Creapure (Creatine Monohydrate)

Supplementing with creatine increases the amount of free cellular adenosine triphosphate (ATP) available in the body. ATP is a primary energy source that helps with various biological processes including muscle contraction. This energy also helps to fuel high-intensity, short duration exercise such as weight lifting, sprinting, or any other exercise that uses fuel quickly.

This, in turn, may help to improve lean mass, strength, and recovery.

Pump: L-Citrulline

The primary role of L-Citrulline in the body is to support the optimization of blood flow to the tissues, which is critical for helping you not only perform your workouts to the best of your abilities, but also to speed up recovery.

L-Citrulline functions in the body by being converted to L-Arginine and then into nitric oxide (NOS). This nitric oxide is then going to be involved with vasodilation. This vasodilation is what helps increase the amount of blood and oxygen that is delivered to the working muscles, helping to prevent both mental and physical fatigue.

L-Citrulline molecule

Pump: L-Arginine AAKG

L-Arginine alpha-Ketoglutarate is a cell volumiser. This means it can help to expand cells in the body, which may lead to a greater delivery of nutrients including glucose, amino acids, and oxygen.

It also increases nitric oxide production, which in turn can increase vascularity and help to get a better pump in the gym - especially for those undertaking hypertrophy style weight training. Therefore, supplementing with L-Arginine has been reported to help boost muscular endurance and stamina.

L-Arginine AAKG molecule

Repair: Glutamine

L-Glutamine is the most abundant amino acid in the body, and is the primary transporter of nitrogen to muscle cells.

Intense training or increased stress to the body (such as with an injury) can lower the body's natural stores, and glutamine depletion may result. Supplementing with glutamine during these periods may

L-Glutamine molecule

Repair: BCAAs

There are three Branched Chain Amino Acids (BCAAs) - L-Leucine, L-Isoleucine, and L-Valine. These essential amino acids cannot be produced by the body and make up about 1/3 of amino acids present in our body.

BCAAs can be depleted from muscle under intense training, and a deficiency in any one of them may cause muscle waste (catabolism).

Because branched chain amino acids are metabolised in skeletal muscle they may provide fuel (energy) for muscle during exercise.

Amino acids are responsible for protein synthesis and BCAAs may be an important component for effective muscle growth and improved recovery.

Tastes bad first 1 I have tried
Review by: Matt on Thu, Sep 16, 2021 6:58 AM
Mixes easy, taste is pretty good. Certainly can feel the tingling during the workout and in my opinion has helped with reps and weights.

I use this religiously pre training sessions, I struggle with motivation otherwise. Good taste, makes my face tingly as. Recommend

Bit of a funny after taste but you get used to it. I like how this isn't packed with over powering sweeteners. Great pre-workout
Review by: Ben on Wed, Jun 2, 2021 9:38 AM
Love everything about it apart from the taste.
Review by: Kurtis on Tue, May 11, 2021 4:53 PM
Very effective, I won't train without it. Makes your workout more intense, leading to more gains. Does not make you jittery like caffeine or energy drinks.
Review by: Michael on Mon, Apr 19, 2021 2:17 PM
MUCH nicer than a lot of the other brands because I only have to add a little bit of water whereas before on other brands I'd have to fill up a whole huge drink bottle and even then it was sickly strong. Will never have the mainstream brands again. This stuff tastes good and kicks in fast. Recommended to have immediately before workout
Review by: Anonymous on Tue, Apr 13, 2021 7:22 PM
Great taste and easy to drink first thing in the morning. Definitely notice the difference in performance when I don't use Pre Workout. Must also say that NZ Protein are super fast with delivery, even to a rural address. Ordered this 2pm and it arrived the next morning.

Great taste and works well! I only use half a scoop and that is suffice for me
Review by: Sophie on Wed, Feb 24, 2021 6:40 AM
Great product, definitely gives you the boost before workouts. Watermelon flavor is okay.
Review by: James on Tue, Nov 10, 2020 6:42 AM
Only used a couple of times and it is good. I got the tropical flavor as the other was sold out. For $40, I do question whether I need it for the amount you get but other than that it's a good product
Review by: Ronan on Mon, Sep 21, 2020 10:43 AM
Great tasting with no weird aftertaste. Gave me a great boost before my workout. Not overly sweet either which is great!
Review by: Payal on Thu, Sep 3, 2020 2:44 PM
Makes me itch a little but other than that great product and the flavor isn't too strong like some other pre workouts
Review by: Zane on Wed, Jul 8, 2020 7:08 AM
Back to basics. Effective product.

Great, works.

I really liked the Pre Workout (NOS) to be honest I would like to have more options about flavours. Previously I took the Tropical Flavour, but I only get to take it once, thereafter I started to use the Watermelon since then I am using it and so far so good for a while.

Has what you want, Does what you need 5/5
Review by: Anonymous on Tue, Mar 3, 2020 8:12 PM
Second time buying this, I loved the Tropical but tried the Watermelon this time. Both amazing flavors. Flavor is more subtle than other brands. But I love that this pre workout has only 150mg of caffeine yet still gets me in the zone and provides a great pump. Other preworkouts are shoved full for 300mg caffeine or more! But this one has quality ingredients to promote a great workout every time. I really like how it also contains 3g of creatine!

Pump was great, not a huge hit on you but definitely gives you that good clean focus. The taste was pretty surprising and as always with these products so damn good.
Review by: Swordfish on Fri, Oct 20, 2017 8:29 PM
I've been using this for a while now, I like it because it doesn't taste sweet and fake
Review by: Jed on Tue, Jun 13, 2017 8:35 PM
Tastes great not like other pre workouts and gives a good muscle pump but don't get that crash afterwards

Decent tasting, great value pre workout. Good quality blend. Overall grade: A+
Review by: Anonymous on Sat, Jan 21, 2017 9:56 PM
The tropical flavour is pleasing and easy to drink when consuming this Nos product. The pumps through the workout are awesome, increased vascularity is enhanced when lean. The muscle fullness created from the great workout supplied by the NZProtein Nos product gives satisfaction that results are imminent
