Magnum Fasted Cardio Preview

At the 2019 Olympia, Magnum had one of their largest booths to date giving out tons of samples and they also won two awards from Popeye’s Supplements Canada (Test Booster of the Year for their “Thrust” product and Fat Burner of Year for their “Heat Accelerated” product). Also at the booth was a graphic of a new product called “Fasted Cardio” that wasn't being sampled and the formula wasn't disclosed and not much was revealed at all. We didn’t hear any more on Fasted Cardio in 2019 but earlier this year we heard there was a new fat-loss product coming from Magnum. That’s it! Last week, Magnum CEO Marcus Kaulius did a post and asked

What kind of CARDIO do you do? Only one answer: FASTED.” 

Why did he write these specific 2 words in all caps? Was there a clue in his post? We thought so and it looks like the name of the new fat-loss product is in fact Fasted Cardio.

What’s In Fasted Cardio?

Magnum hasn’t revealed this (yet) but one clue was given by Markus Kaulius when  “This product is so strong and works SO fast - the first dose made me sweat so hard!!!”

GBB (Gamma-Butyrobetaine Ethyl Ester HCl)?

One ingredient that could do that is GBB (Gamma-Butyrobetaine Ethyl Ester HCl) which is a unique L-Carnitine precursor. GBB essentially converts into Carnitine in your body but has the unique effect of making you sweat. Science hasn’t explained why it makes you sweat but some theorize it’s simply because the conversion from GBB to Carnitine is an exothermic chemical reaction. The first product we saw this ingredient in was Jay Cutler’s original Legend Pre-Workout, it later in Beast Sports Super Sauna and Steelfit and VMI Sports also included it in some of their formulas. We don’t know for certain if Magnum has included GBB in Fasted Cardio but it would be a great addition if they did. If GBB is in the formula, it would make sense to include L-Carnitine since the two act in synergy. With Covid-19 hitting us, the price of Carnitine has gone up so but we’re hoping Magnum did include this ingredient. 

Grains of Paradise?

The other ingredient it could have is Grains of Paradise the primary constituents of which are 6-gingerol, 6-paradol, 6-shogaol, and 6-gingeredione. This has appeared in a number of fat-loss and pre-workout products due to its ability to stimulate Brown Adipose Tissue (BAT), producing a thermogenic effect at a cellular level. Grains of Paradise also helps convert less metabolically active white adipose tissue over to the highly active Brown Adipose Tissue. Again, we don’t know if they included this in the formula but it would be a great addition. 

Cayene Pepper, Capsaicin, Piperine and/or Green Tea?

Cayene Pepper, Capsaicin, Piperine and to a smaller extent Green Tea (via thermogenesis) have all been linked to thermogenesis/heat production. But Magnum has been tight sealed about this formula so we don’t know if any or all of these are in Fasted Cardio. Our best guess is no on the Green Tea as it’s an ingredient that we don’t see in formulas often any more. 


We definitely think you’ll see caffeine at the heart of the formula to give users energy while doing cardio. Drinking a coffee in the morning before cardio or taking a shot of caffeine is a great way to stimulate fatty-acid release from adipose tissue to be utilized during cardio. Caffeine also increases power output allowing you to get more out of your cardio, especially when you’ve been fasting all night!

BHB Salts and/or MCT Oil Powder

Fasting before cardio primes the body to get into ketogenesis, allowing you to burn more fat. Taking BHB salts or MCT Oil powder would help provide a fast-acting fuel that wouldn’t take you out of ketosis. Since we live in a keto world these days, we wouldn’t be surprised to see BHB salts (ketones) and/or MCT Oil powder in Fasted Cardio. But we may be way off! 


Magnum has revelaed the key drivers in the Fasted Cardio formula below which is very close to what we predicted but we weren't 100% right on our guess! 

Fasted Cardio Specs

Fasted Cardio contains 156 to 164 gram container (depending on the flavour) delivering 40 servings in total. Each contains 4.1 grams in each serving which is not a huge dose but remember, this isn’t a traditional pre-workout formula it’s more of a cardio pick me up. It comes in 3 flavours (Molotov Cocktail, Shock Therapy and Rise & Grind). Sign up on the Brand’s website for updates about this and other Magnum products. We’re told they’re revealing the formula this week. To have a new supplement previewed or to submit supplement news, email info@muscleinsider.com
