  • Mostly Underdosed
  • Not Effective

Quick Summary

This song from Kanye West finally makes sense after using Jetfuse for a while. One and a half month of wasted workouts. Just some minor pumps. Underdosing is the keyword here.


35 years old financial auditor trying to balance life with three kids and a busy job. Trying to get in some quality time at the gym in the meantime. When I manage to squeeze in some gym time I can use all the supplement help that's out there.
First of all thanks to the SR troops and Clipper for the bounty (oldscool). Everybody uses a pre workout. I have been trying some different ones with more and less satisfaction. Jetfuse being an absolute low. Although I am totally open to using a non healily stimmed pre workout Jetfuse did not do a lot of good overall

Ingredient Profile

The ingredient profile consists of 4 categories, the first one being vitamins, mostly B12 and some phosphor, sodium and potassium for hydration.
Volumizing blend
2,25 g of Creapure Creatine
2g of taurine
1,5g of waxy maize
1g of L-arganine
1g of L-Citrulline
1g of Alpha-Ketoglutarate

Energizing blend
1,5g of Carnosyn beta alanine
250mg L-Tyrosine
150mg Caffeine Anhydrous
100mg Green Tea Leaf Extract (50% caffeine)
100mg Glucuronolactone

Recovery blend
1g L-Glutamine
500mg L-Leucine
250mg L-Isoleucine
250mg L-Valine
125mg Betaine HCI
125mg N-Acetyl L-Cysteine
5mg BioPerine Black Pepper Fruit Extract (Piper nigrum)
50mg Mucuna Pruriens seed extract powder (60% l-dopa)
5mg Cinnamon Bark Powder (Cinnamomum cassia)

The volumizing blend is nicely balanced in terms of ingredients but mostly underdosed The amount of creatine is too small to be considered a decent dose. The amount of Taurine is fairly dosed. Taurine helps with the cramping., increases blood flow. The suggested dose is between 500mg and 2g. Waxy maize supposedly will restore muscle glycogen and increase absorption of other supplements. 1,5g seems like a small dose. L-Arganine is the amino acid that directly produces nitric oxide. The standard pre workout dose is 3-6g. 1g is heavily underdosed. L-Citrulline supplementation results in reduced fatigue and improved endurance and is considered a better form of L-arganine. L-citrulline supplementation improves the ammonia recycling process and nitric oxide metabolism. For pre workouts, 6-8g is advised. 1g is only a fraction of this. AAKG is a form of L-arganine. Suggested dosage is between 1,5 and 3g, so 1g -again- is not enough.

The energizing blend is not too heavy on the stims. This should not be a problem, and some people actually prefer this. I had some good low stim PWO's before. Most standard PWO carry an amount of 250-300g of caffeine. Carnosyin Increases muscular endurance, increases lean mass. Suggested amount is 2-5 grams, so 1,5 is underdosed. L-Tyrosine is an amino acid that is used to produce noradrenaline and dopamine. I always believed this to be more of a focus ingredient, but with Jetfuse it is listed in the energizing blend. Suggested before exercise is 0,5-2g. So yet again underdosed. Glucuronolactone is used in energy drinks, 100mg is just a fraction. A typical can of red bull contains 600mg.

The recovery blend consists of 1(?)g of bcaa's in a 2:1:1 ratio. A very low dose when stacked against your typical bcaa product which contains on average 5 grams. 1g L-Glutamine for recovery and muscle building. The optimal dose remains debatable, but 1g is a small dose compared to other supplements. 125mg Betaine HCI basically beet root. Suggested is 1,25g twice a day. HCI should absorb better, but 125mg seems a real small amount.

I could go on, but the overall conclusion is that with 20 supplement ingredients, most of them are (heavily) underdosed. This supplement uses a wide array of ingredients, but if you underdose every ingredient, all you get is a whole lot of noting. The effectiveness of this ingredients was as to be expected.


No issues on this part. A scoop is pretty large, but mixes just fine. I got the exotic fruit flavour which tasted pretty good. Not too sweet, not bitter.


I believe this pre workout actually hindered my progress. My workouts were lethargic. Even with small amounts of stims I experience much better workouts before. Energy was really low. Jetfuse did cause some extra sweat, which I consider to be good. I did experience a small pump effect, but way to minor to give this PWO a good rating on the pump section. The most pronounced effect I experienced was muscle cramping after only a short workout. The amount of taurine is fairly dosed so this really surprised me as this usually does the trick. Overall I am very happy to finish this tub and move on to something else. An overall disappointing experience.


At a price of 25 dollars for 30 servings this isn't an expensive pre workout. But you get what you pay for here. At 20 dollars, or even less, I would not recommend this PWO. Even for this price you can get a better value for your dollar.

Side Effects



The ingredient profile is massive. This is also the main problem with this PWO. The profile is just too large and filled with inderdosed ingredients. I think it would be better to make some clear choices on the ingredients to include, and include the scientific proven dose. I experienced some minor pumps, but overall this pwo hindered my progress. Honestly, this is one of worst pwo's I have tried.
