  • It eliminates the main problems that made all older, last generation preworkouts inefficient.*
  • It creates energy, intensity, and focus in a matter of minutes*

The key pharmaceutical grade ingredients Magnum PRE-FO are:

  • Citrulline Malate
  • Acetyl-L-Carnitine
  • Agmatine Sulphate
  • French Pine Bark Extract (90% Oligomeric Pro)
  • Bacopa Monnieri Extract (55% Bacosides A&B)
  • L-Theanine
  • Caffeine Anhydrous & Dicaffeine Malate

Citrulline Malate

Is an amino acid that increases muscle energy, improves stamina and resistance, to fatigue, accelerates recovery post training, and maximizes blood flow. It also boosts amino acid delivery to skeletal muscle, leading to increased muscle growth.*

It increases energy levels by removing ammonia from the body, allowing you to train harder and for longer periods of time.


ALCAR is a neural repair nootropic that easily crosses the blood-brain barrier to remove damaged fats from the brain and supports neural connections. It also increases the production of acetylcholine, as well as dopamine, the feel-good hormone. This results in an increased mental alertness and an elevated mood all while protecting the brain.*

When combined with Caffeine ALCAR can and will provide a prolonged burst of focus. ALCAR also reduces jitters usually associated with high stimulant ingestion. This gives you a clear, high-energy state, with intense focus for hours. ALCAR also helps with muscle recovery, and helps in the conversion of fat to energy.*

Agmatine Sulphate

Not only does agmatine sulphate help create amazing muscular pumps through better, and stronger vasodilation, it also is an excellent nootropic agent. In the prefrontal cortex, the area of the brain responsible for working memory, attention span, and executive functioning (the ability to achieve goals and get things done), agmatine increases serotonin (aka the happy hormone) and norepinephrine/noradrenaline. By increasing serotonin, Agmatine can improve your sense of well-being and boost mood. Agmatine increases norepinephrine by modulating Alpha-2 receptors, which play major roles in the prefrontal cortex's main functions, such as working memory, attention, focus, and the ability to set and hit goals.*

French Pine Bark Extract (90% Oligomeric Pro)

Stimulates eNOS in arterial cell walls, expanding blood vessels up to 78%. Pine Bark Extract has been found to greatly enhance blood flow and oxygen transport to muscles, allowing for massive muscular pumps as well as accelerated recovery from high intensity training.*

Bacopa Monnieri Extract (55% Bacosides A&B)

Is an herb native to India long known to aid memory, concentration and learning. The active compounds in Bacopa are called bacosides. These compounds regulate serotonin and dopamine, which contribute to overall cognitive power, energy, and concentration.*


L-Theanine is known to be a calming agent. When paired with caffeine, it negates the undesirable side effects, but provides an intensified nootropic experience. It reduces the rough edges that high dose caffeine can create, leaving with you a clean energy feeling that will last long after your daily workout.*

Caffeine Anhydrous & Dicaffeine Malate

Caffeine stimulates your central nervous system to give you both physical energy and mental focus, which results in superior concentration and drive in the gym.*

It can also help you burn more fat by releasing more fatty acids from fat cells, leading to weight loss.Caffeine improves total exercise endurance levels and increases the amount of energy burned from fat fuel sources.*

Dicaffeine Malate is a mix of caffeine and malic acid that replenishes the energy produced by caffeine, while calming the digestive effects that too much regular caffeine can cause.*

I have been using preworkout for 10+ years and never came across a tub that has a scoop on the top for you ready to go. This gives me teary nice of how nice it is that you don't have to dig down the tub with your fingers to look for the scoop. Beautiful, just beautiful. Tastes & Mixability: 9.5/10 This is one of the very few pre workout that I actually enjoyed the taste. It is not overly too sweet and doesn't have that strong smell or after tastes to it. The is mixing works great with no clump. I tried mixing 20oz of water with 1 scoop and 2 sccops and no issue with it at all. Everything get disolved. Focus: 9/10 I tried with one scoop the first two days and found that it allows me to be focus quite good. The next couple days when I got very little sleep and didn't have the energy in the tank to train so I upped to two scoops and was golden. I got me moving due to being so focus. Pump & Energy: 8/10 Being having a high tolerance with caffiene, I find this area to be a little under dosage for my liking. I didn't really find much energy with this. It could be due to the very lack of sleep that I have gotten the last couple weeks. As for the pump goes, got a pretty good pump with it. Overall: 9/10 With all that said, is a solid product. Would definitely purchase and use it again in the future due to the "focus factor" hat it provides. I think I will give the blue shark favor a try when I purchase the next tub. Blue shark looks interesting.

Mixability The picture is 2 scoops in 16oz of water and it mixed up perfectly with about 10 seconds of shaking and some swirls. No loose particles at the bottom at all. Taste They nailed the flavor with this one. It tastes exactly like I remember the candy tasting from back in the day. I put some powder on my finger and tried just a little like that and it was perfect. The directions recommend 8oz of water per scoop, but I definitely found it better with 6oz of water. Really tastes more candy like. Effects/Profile I noticed a pump before I even left for the gym. I'm pretty lean right now, so any pump from carbs, preworkout ingredients, or lifting is quite noticeable. This definitely delivered in the pump department and that's no surprise with 2 scoops yielding 6g of Citrulline Malate and 500mg of agmatine. Pre Fo provided a smooth (but not over the top) energy as well. Stands out more so for the pump in my opinion. I do, personally, prefer some beta alanine and creatine in my preworkouts too just for convenience, but that's by no means a deal breaker as it's too easy to just supplement with those additionally. Overall this is an awesome preworkout from a great company and I'll happily recommend this to anyone chasing that pump.

I have been using this product for about 2 weeks now - different times of day, empty stomach, right after eating, different types of workouts and each time it's performed VERY well. First the taste: awesome. Sort of a light blue raspberry that's wonderfully sour (if you like that sort of thing which I definitely do.) I love the micro-dosing and 50 servings per tub. I've been using PREs for years and one scoop of PreFO still gets me going when it's time to train. I don't need to double up on the scoops which is awesome. Mixability, of course, is perfect. Beware: it's not blue! No artificial colors which is great, but for some reason I thought it would be blue haha. A great product from Magnum that will definitely be a staple in my supp cabinet - or in this case freezer to avoid any potential clumping :-)

If you love sweet, candy like, flavors than this is gold; I can only imagine based off of this experience that all of the flavors are just as well done, so go for whichever appeals most to you personally. I loved the strawberry flavor it had and the marshmallow being as well done as it was is just icing on the cake. Add in a great profile that is (in my opinion) perfect at 2 scoops and it is a killer combo. I had great energy, pumps, and a solid focus which kept me going throughout my entire routine no problem.

I got to try this out through a promotion here, and I am so glad I was picked for it. This became one of my favorite preworkouts the first day I used it. I picked this flavor, because I was tired of fruit punches, and raspberries, and despite not typically being a big apple flavor fan, I figured I'd give it a shot. I mixed two scoops in about 6oz of water, and set it down for a minute because I was doing something at the time. I pick it up without thinking about it a few times, and drank it a bit. About half way down I realized "oh wait, this is good!" I forgot I was drinking a preworkout, it wasn't overwhelming, it wasn't sickly sweet, or too sour. It was candy with a kick of apple flavor at the end. I could easily drink this even more concentrated if I wanted to. As for ingredients, no prop blends, simple effective ingredients, and a nice small scoop. I can't be the only one who's stomach hurts a bit with some of those massive doses of preworkout. Even two scoops was perfectly fine for me. I'll be honest, I'm not sure of the benefits of some of these ingredients, it's something I'll have to look more into. However, if there's three things I like to see it's citrulline, l-carnitine, and caffeine. Anything else is gravy, again, especially if it still fits in a smaller serving. Three grams of citrulline is good, and generally works well enough, but I do prefer closer to 5g, I prefer a bit more l-carnitine per serving too, 200mg of caffeine is pretty solid. However, this works for me. Some days I want a little boost, and a scoop of this is perfect, used two scoops Mon, one on Tues, and had great workouts both days. On the days I want a little more, I can double up without getting nauseated, and with 50 servings per tub I can vary the amount depending on the day and know I won't run out too soon. I have a pretty good tolerance to caffeine though, and apparently l-theanine is a calming agent, so I guess that's meant to offset the caffeine a bit? Overall, my last two workouts were great, I had a solid pump, great focus, and felt energized. I found this very effective, and the flavor was a pleasant surprise in how much I enjoyed it. Would absolutely recommend.

This is my absolute favorite pre-workout ever. The flavours are amazing and I get such great focus and energy for my workouts. Since there's two different types of caffeine with two different half lives there's no crash! The nootropics in the formula are a great addition and I feel like I'm getting the most out of my time in the gym when I take prefo.
