Iron Addicts SideWalk Kraka: An Evidence-Based Review

SideWalk Kraka is a pre-workout supplement by Iron Addicts Supplements, the brand headed up by one of the most influential figures in the fitness industry, Mr. CT Fletcher himself.

In fact, this supplement is SO CT Fletcher that it actaully says his catch phrase on the packaging: It’s Still Yo Motherfuckin’ Set.

Sidewalk Cracka



CT Fletcher, and whoever else is behind the Iron Addicts Supplements line, actually doesn’t make too many claims about what Sidewalk Kraka will do for you which we actually think is a good thing.

Too many brands plaster their packaging with things like “explosive strength” and “lazer focus” which is usually misleading to the consumer.

The average supplement consumer may still be clueless, but more and more people are starting to understand how to interpret a Supplement Facts panel and decide for themselves what a particular supplement is capable of.

Based on the Supplement Facts, Sidewalk Kraka will provide:

  • High Levels Of Energy/Focus
  • Better Muscular Endurance
  • Accelerated Fat-Loss

It’s an impressive Supplement Facts panel, for sure, but let’s dig in a little deeper to see if Sidewalk Kraka can provide all those things…

Sidewalk Kraka Ingredients

As previously stated, the ingredient profile of Sidewalk Kraka is pretty comprehensive.  It contains several physical performance enhancers as well as a few stimulants (including a hefty dose of Caffeine)…


Beta-Alanine is a (beta) amino acid which is used by the body to produce Carnosine, a dipeptide composed of Beta-Alanine and Histidine, higher levels of which are associated with better musular endurance.

Carnosine works by reducing Lactic Acid build-up in muscle-tissue, thereby effectively delaying fatigue for longer.  Beta-Alanine has proven to be a highly reliable way of increasing Carnosine in muscle tissue, having been shown to do so in several studies at varying doses.

It takes time to accumulate, but at 3-6g/day, Beta-Alanine supplementation will increase your muscular endurance to noticeable degree within 1-2 weeks.  Lower doses would require longer periods.  There is no need to cycle Beta-Alanine and there’s no way you can OD on it.  It’s super safe.

The only thing you might want to be aware of–if you’re new to Beta-Alanine–is that high doses tend to cause a tingling sensation known as Parasthesia which is simply a harmless side effect which goes away over time.

Sidewalk Kraka contains 3.2g of Beta-Alanine, a standard (clinical) dose which will definitely improve your muscular endurance over time.

Agmatine Sulfate

Agmatine is a metabolite of Arginine which hasn’t been studied much in humans but has been shown in vitro (in cells, not humans) to activate Nitric Oxide Synthase, the enzyme which initiates the production of Nitric Oxide.

If it’s pumps you want, boosting Nitric Oxide is the goal.  More Nitric Oxide production means more blood flow to the muscles resulting in pumps and improved performance.

However, Agmatine has never been studied in humans in the area of performance enhancement, despite it’s widespread use in pre-workout supplements these days.  It’s perfectly safe (it’s been studied for a lot of other things in humans), but as a pump/performance enhancer it remains speculative.

Some people swear by it, but until we have some actual studies it’s really tough to say how useful it is.  Whether or not it’s effective, Sidewalk Kraka contains a sizeable (1000mg) dose, more than you’ll find in most pre-workout supplements.

HydroMax Glycerol

Glycerol is an Osmolyte, meaning it has the ability to regulate the amount of water in cells.  Glycerol supplementation has been shown to preserve hydration status in long-duration endurance exercises and exercise under extreme heat conditions, but this isn’t so much performance ‘enhancement’ as ‘preservation’.

As a pump agent, it hasn’t really been studied but the mechanism certainly exists. It’s the same mechanism underlying the above-mentioned benefits.  By drawing additional water into muscle cells, Glycerol increases cell volume which may result in greater pumps…assuming you drink plenty of water along with it.

HydroMax, a Glanbia brand, is the preferred form of Glycerol and Sidewalk Kraka contains 1g of it.  Not bad!

Choline Bitartrate

Choline isn’t a vitamin by the technical definition but it is most certainly an essential nutrient, required for a wide array of body processes.  Most notably, Choline serves as substrate for production of Acetylcholine, the neurotransmitter most closely associated with memory, learning, and muscle contractions (the mind-muscle connection).

Unfortunately, Choline Bitartrate is the least bioavailable source of Choline, Alpha GPC and Citicoline being far superior in terms of increasing Acetylcholine production.

That said, there may be some marginal benefit associated with the 500mg dose of Choline Bitartrate present in Sidewalk Kraka.  It’s not a majorly important ingredient.

Caffeine Anhydrous

Caffeine pretty much forms the basis for just about every stimulant-based pre-workout supplement.  Why?  Because it works!

How much Caffeine you can tolerate/enjoy/benefit is entirely individual and varies considerably from person to person.

That’s the reason the pre-workout category has split into sub categories based on stimulant level (non-stim, low-stim, high-stim, insane-stim, etc.).

Sidewalk Kraka contains 300mg of Caffeine per serving which is a perfectly reasonable dose, capable of providing the average person with a noticeable boost of energy/focus, but the effects are definitely amplified by the additional stimulants in the formula.

To put it plainly, Sidewalk Kraka will hit you harder than just 300mg of Caffeine would.  So let’s talk about the other stims…

N-phenethyl Dimethylaminne Citrate

N-phenethyl Dimethylamine is a synthetic stimulant that has been making it’s way into more and more pre-workouts ever since DMAA got banned (or did it?).  It’s more like Phenyethylamine (PEA) than 1,3-Dimethylamylamine (DMAA), but it’s a stimulant nonetheless and, apparently, one worth taking…

Here’s the thing about N-phenethyl Dimethylaminne Citrate…Nobody really knows much about it.  PricePlow wrote an article on Eria Jarensis/N-phenethyl Dimethylaminne Citrate which is super well-researched and covers everything you could possibly need to know.

According  to PricePlow:

“has a very nice euphoric effect.” and  is “no DMAA in terms of strength, but it might just be the next best new thing.”

But the truth is you won’t know how N-phenethyl Dimethylaminne Citrate will effect you until you take it.  Seriously though, read that PricePlow post if you want to know more.  In fact, read all of PricePlow’s posts!  They do awesome work…we just wish they’d right a guest post every now and then:(

Okay back to the formula…


This is yet another synthetic stimulant which we’re not going to even try to act like we understand.  Once again, we’re turning this one over to PricePlow.  They’ve put together a post that covers everything there is to know about 2-Aminoisoheptane, along with a little logical speculation about what you can expect from it.

Sidewalk Kraka contains 125mg of 2-Aminoisoheptane.  What does that mean?  We have no idea…


Theobromine is a natural component of Cocao.  It’s in the family of chemicals known as Xanthines, along with Caffeine.  While it is considered a cardiac stimulant (increased heart rate), it is not a psychoactive stimulant, meaning it won’t give you a rush of “energy” like Caffeine.

Still, it has implications for performance enhancement in that it may allow for optimal oxygen intake during exercise.  It hasn’t been studied, but the mechanism exists.


Theacrine is a stimulant which is found naturally in a type of Chinese tea called “Kudingcha”.  It’s usualy sold under the brand name TeaCrine which is owned by Compound Solutions, the same company that distributed CarnoSyn Beta-Alanine for a while.

Needless to say, Theacrine has been popping up in tons of different supplements, from pre-workouts like Sidewalk Kraka to Nootropic/Energy supplements and fat-burners.

Theacrine functions somewhat similarly to Caffeine, but preliminary data (from mice) suggests it doesn’t result in as a much of a tolerance build-up (one of the main problems with using Caffeine alot).

Theacrine may be a stimulant, but works differently than Caffeine and appears to be more selective for Dopamine than Noradrenaline (the primary neurotransmitter released by Caffeine).

So, is Theacrine a replacement for Caffeine?  Absolutely not, but it may enhance the energy/focus aspect of Sidewalk Kraka by working side by side with Caffeine.

Sidewalk Kraka contains 50mg of Theacrine (TeaCrine brand) which seems to be the standard, though not enough research has been conducted to determine an optimal dose yet.


Naringin is a Flavonoid found in cirtus fruits which is commonly extracted from Grapefruit and is one of the primary molecules responsible for the weight-loss benefits associated with Grapefruit.

It’s not a psychoactive molecule, so it won’t give you focus and energy like the few ingredients we just discussed and the one we’re about to discuss (Rauwolscine), but it may certainly enhance the fat-burning aspect of the Sidewalk Kraka formula.

For that reason, we’d consider it a unique, useful addition to an already comprehensive formula.


Rauwolscine is a steroisomer of Yohimbine, meaning they are identical in terms of chemical structure but differ in terms of the position of the individual atoms that comprise each molecule.  You don’t have to be well-versed in Chemistry to get the point that this makes Yohimbine and Rauwolscine very similar in terms of function.

They’re both alpha-adrenergic receptor antagonists (meaning they inhibit the receptors that put a stop to fat-breakdown), but Rauwolscine is much more potent on a milligram for milligram basis.  Yohimbine requries doses of 10-20mg to burn considerable amounts of fat, but Rauwolscine is effective at doses of 1-5mg.

Additionally, Rauwolscine may improve mood and have more a psychoactive effect than Yohimbine, especially when combined with the other stimulants found in Sidewalk Kraka.

Sidewalk Kraka Ingredient Takeaway

The Sidewalk Kraka ingredient profile is SOLID to say the least.  It provides a great balance of physical performance enhancing ingredients, all dosed effectively, and a unique stimulant profile that will provide even the stim-junkies with a noticeable, sustained boost of energy, focus, and drive.  This is one pre-workout that is effective all the way around!

Is Sidewalk Kraka Safe?

Is Tylenol safe?  Only when taken as directed (maybe not even then).  Don’t over do it on Sidewalk Kraka and you won’t have to worry.  It’s definitely a “high-stim” pre-workout which means it’s not for everyone.  If you’re sensitive to stimulants you should start with half a serving to assess tolerance.  Just follow the directions and don’t be stupid!

CT Fletcher Just Stepped Up His Game

We’re not sure what Iron Addicts Supplements looks like behind the seens, but it appears that CT Fletcher is at least a part owner (if not majority owner).  Whoever else is involved definitely knows what they’re doing when it comes to formulations, so we’d say CT made a good move with this one.

Most fitness celebrities that release supplements are just trying to cash in quick.  The supplements usually suck and they may lose some fans but they get rich quick.

CT Fletcher, on the other hand, clearly isn’t motivated by money.  He’s quite possibly the most inspirational person in the fitness industry and the quality formula of Sidewalk Kraka is a testament to his reputation.  This is one celebrity-endorsed/owned product that is DEFINITELY SuppWithThat approved.

Where To buy Sidewalk Kraka

Sidewalk Kraka can be found at the following retail stores:

And probably a bunch that we’re not aware of.  If you know of a site that also sells Sidewalk Kraka, let us know in the comments below.

The Bottom Line

Sidewalk Kraka isn’t just some celebrity-endorsed nonsense.  It’s actually a very well formulated, clinically-dosed, high-quality supplement which bears the name and catch phrase of one of the most well-known, inspiring people in the fitness industry, CT Fletcher.

If you like your stimulants, meaning intense energy and focus that last a while, but also value physical performance enhancement (endurance, pumps, strength), then give Sidewalk Kraka a shot…Then go thank CT Fletcher for being the one fitness celebrity who put out a product that doesn’t suck.
