Giant RUSH: Straight Stim Pre Workout by Giant Sports

Update: Giant Rush is now in America! See the updated label below!

Giant Sports Giant Rush

Giant Rush is the new DMHA stim pre workout from Giant Sports that’s all about energy.

Regular readers of our blog have no doubt seen the four letters D-M-H-A showing up on rather frequently as of late. We’ve seen a rash of new pre workouts hitting the market that include this stimulant due to its hype as the “evolution of DMAA.”

However, every other time we’ve encountered the ingredient, it’s been shrouded behind a prop blend. That’s no longer the case with today’s featured product.

Giant Sports is the first manufacturer to openly disclose just how much DMHA is included in their brand new pre workout Giant Rush, and today we release the study proving that it’s truly found in nature!

See the updated label below.

Giant Rush Ingredients

There’s no mistaking Giant Rush with the host of all-inclusive pre workouts that have been flooding the market lately. This is purely about the stimulants. It’s three simple ingredients that will give you the rush to get in the weight room and crush some iron!

  • Caffeine Anhydrous (200mg)

    Giant Sports Giant Rush Ingredients

    Giant Rush is all about the stims and it’s the first product to actually reveal how much DHMA is actually included in it’s energy blend.

    You can’t have a stimulant based pre workout without the godfather of all stims, and Giant Rush is no exception. 200mg is a moderate dose that should be more than enough for most people, but for the real stim-fiends in our audience you’ll more than likely need 1.5 scoop minimum.

    Keep in mind though, this isn’t the only stimulant your body will be facing in Giant Rush, we’ve still got 2 more to go.

  • Kigelia Africana Extract (125mg)

    Here it is! Thought we left out the DMHA that we mentioned up top? Nope!

    This is one of the many other names you’ll see the breakout new stimulant of 2016 labeled as. You’ll also see it displayed as “2-aminoisoheptane” (the vague name that we don’t like) and Octodrine (a more specific name that is synonymous with 2-amino-6-methylheptane), but we now know where the stimulant comes from thanks to Bruce Kneller of Giant Sports.

    Aliphatic amines found in nature


    DMHA with 2D Structure with PEA Backbone Highlighted

    Both 2-amino-5-methylheptane and 2-amino-6-methylheptane (DMHA) are of the class of aliphatic amines[1], DMAA being the most well known, that exist in nature. These are both labeled under 2-aminoisoheptane, and they behave similarly, but are not the same. When extracted and used in supplements, they impart a marked uplift in mood that’s unlike most other ingredients out there.

    Giant Rush contains 125mg of the stimulant (coming from kigelia), and we’ve really been enjoying in this and the other products that we’ve tried it in.

    DMHA also imparts a significant increase in energy and focus leading to some of the most productive workouts you’ll experience if you’ve never ventured into the land of aliphatic amines previously.  Other uses for the stimulant include applications in lowering cholesterol and lipid levels, as well as treating diabetes.[2,3]

    So if there are two new aliphatic amines out there, what stimulant is really in Kigelia?

    The mysterious DMHA study revealed!!

    Giant Sports Myra Rogers

    Myra Rogers is the newest athlete added to Giant Sports. Was it Giant Rush that wooed her?

    The big question was how we knew there is DMHA / octodrine found in nature. We’ve seen the 2-amino-5 version in walnut tree bark extract, but not 2-amino-6 version we originally blogged about. Wonder no more – kigelia is the answer. 100% credit is given to Bruce Kneller of Giant Sports for making this most major find – right there in plain sight nonetheless!

    A study published in late 2014 titled Metabolomic Profiling of Kigelia africana Extracts with Anti-Cancer Activity by High Resolution Tandem Mass Spectroscopy has located it[6] – and when you look at the benefits of Kigelia fruit, it all starts to add up.

    The fruit has anti-cancer, antibacterial, and pain relieving properties – some of the things that 2-amino-6-methylheptane / octodrine are known for… on top of its wonderful euphoric stimulant feeling! Now the story is complete. Thanks again Bruce!

  • Bai Mudan™ White Tea (25mg)

    Bai Mudan is a variety of white tea made from the younger leaves of the Camellia Sinensis plant that gives a fuller, more rounded flavor than the other well-known form of white tea Bai Ho Yinzhen.

    White tea leaves contain caffeine (although much less compared to coffee beans) as well as polyphenols. Research surrounding the fat loss and heart health benefits of regular tea consumption is pretty straightforward.[4,5] This is mostly attributed to EGCG’s role as a strong lipolytic agent in the body

    This white tea is one of the most potent tea extracts we’ve ever experienced.

Available Flavors

Giant Rush Review

CJ got his hands on 2 tubs of the new Giant Rush, and has been LOVING it so far! Stay tuned for a FULL review. PS: Don’t let this picture deceive you — these tubs are tiny!

So far we’ve have confirmation of three flavors: Raspberry Rush, Mango, and Green Apple. These are marketed towards Australia, which enjoys different flavors more than the lame grape / fruit punch that American always buy. Giant Sports isn’t known for making a ton of different flavors with their other pre workouts, so we’re going to assume these are most likely the only a few flavors that Giant Rush will offer.

They are most proud of their green apple, although their past mango flavor systems have been our favorite (in the Australian version of Metabolic Bioshock).

Early Reviews

CJ will have a YouTube about this, but he cannot stop raving about it. The blend is simple but spectacular. Three incredible stims.

We believe that the pre workout market has never been stronger, with DMAA and DMHA both rocking the scene. The question is, what is availability in America going to be?

The Giant Rush US Ingredients, available in America

Giant Sports has separated itself from the select few companies who have chosen to tackle DMHA by actually listing the total amount of DMHA included in Giant Rush. This is the kind of open transparency we’re always championing here at PricePlow.

We’d also like to once again thank Bruce Kneller for helping the industry push ahead with this new stimulant – he was completely honest (and right) when saying that it was found in nature, and it is indeed – in kigelia.

We’ll need to wait to see if it’ll be available in America, but if you’re in New Zealand or Australia, this is a must try energy supplement!!!

For those who haven’t gotten a chance to try this new stim yet, this may be one of the most straightforward ways to try it and actually gauge how it affects you since it’s not loaded alongside a bunch of other stims like Higenamine, Hordenine, or Synephrine.

We don’t have an official release date yet, and definitely aren’t sure about America, so for the time being you may need to try on of the many other products that includes DMHA, but when you do, you’ll definitely be able to tell there’s a little something “extra” going on in your workouts.
