Ronnie Coleman Signature Series YEAH BUDDY Extreme Energy Pre Workout Review

Ronnie Coleman Signature Series YEAH BUDDY Extreme Energy Pre Workout Review First Look:

Following a session on the beers the night before with my old room mate when living in London I was feeling not too hungover but not particularly stimulated to do anything energetic.

In fact I spent all of the day at my computer looking for cars because that’s all I could be bothered to do.

Yet, not wanting to waste a complete day sat like a retarded penguin I thought a session in the gym could be just what I needed.

So I hit the kitchen about 90 minutes prior for a bit of sustenance then 15 minutes before lowering myself in to the gym beneath my living room floor I had this pre workout from Ronnie Coleman’s Signature Series.

It mixed well with water and tasted delicious, I was expecting something amazing.

I have already found the best Pre-Workout formula I have ever come across which I use for rugby and I just wanted to try something else to see if it would compare especially as I was feeling shattered.


RELATED: We’ve tried and tested the best pre-workout supplement HERE!

Beta-alanine  – Supplementation of this non essential amino acid aids the production of carnosine. That’s a compound that plays a role in muscle endurance in high-intensity exercise.

That said, studies have not exactly been positive nor entirely conclusive.

L-Citrulline – This is used as a sports performance and cardiovascular health supplement. L-Citrulline supplementation results in reduced fatigue and improved endurance for both aerobic and anaerobic prolonged exercise.

An increase in growth hormone has been noted with exercise, but not at rest.

L-citrulline boosts nitric oxide production in the body. Nitric oxide helps your arteries relax and work better, which improves blood flow throughout your body.

Supplementing can help lower blood pressure in people with pre-hypertension.

This is often found in the best pre workouts.

To supplement L-citrulline to enhance sports performance, take 6,000 – 8,000 mg of citrulline malate about an hour before exercise.

Agmatine – Agmatine is considered to be a neurotransmitter and neuromodulator.

The majority use agmatine injections, not oral ingestion and there is still no evidence that working memory is enhanced with agmatine supplementation.

Choline BiTartrate – Choline is mostly used for either its cognitive boosting properties or as a liver health agent, able to reduce fatty liver buildup.

It may also be a stimulant although this is based on anecdote. Requires around 250-500mg per day for cognitive benefits.

Choline does not offer any significant benefits for aerobic capacity, fatigue or training capacity.

Caffeine – This can assist with endurance, tested athletes saw an edge from caffeine in scientific studies. In some trials, the stimulant boosted athletes’ speed. In others, it helped them last longer before they spent all their energy.

Caffeine also raises the metabolism which means you burn more calories. Some studies show that it can curb soreness after exercise, too. This means you could get back to your training sooner and training means more calories burnt. This is present in all 3 of our Top Fat Burners.

Caffeine Anhydrous is the purest form so always look for that.

Theacrine (1,3,7,9-tetramethyluric acid) – An alkaloid molecule which can be seen as a structurally modified version of caffeine.

However, although it is similar to caffeine whereby it has a sedative effect at relatively low doses, but where this sedative effect with caffeine is at an impractically low dose with theacrine it is the dose normally consumed by tea.

Research on Theacrine is really too sparse though to cast any real assertions.

Synephrine – This increases fat oxidation rate whilst reducing carbohydrate oxidation rate during low to moderate exercise.

Higenamine – Data shows an increase in energy expenditure and kilocalorie expenditure. It also results in a moderate increase in heart rate and systolic blood pressure similar to caffeine.

Phenylethylamine hcl – Used for treating depression and increasing athletic performance. No evidence to substantiate these claims.

Limited supplemental usage due to being rapidly broken down into inactive components.

Yohimbe – Related to Yohimbine, Yohimbe is a powerful stimulant and used to increase fat loss as well as assist with erectile dysfunction. Can cause a host of other problems though, this is in our supplements to avoid list.

Supplementation with yohimbine combined with resistance training does not significantly alter the body mass, muscle mass, or performance indicators.

Adhatoda vasica (Malabar Nut) – There’s really no evidence to suggest there are any benefits to taking this.


We are told to have 1 serving which works out at 8g.

This isn’t big at all and is much smaller than some pre workouts which offer up to and over 20g.

In fact, one could say that this was “LIGHTWEIGHT”. I’ll get my coat…

The taste was incredible but it did make me feel a little bloated.

Benefits & Effects:

It is great to see Citrulline as this can have many athletic and cardiovascular benefits not to mention increases of growth hormone production when working out. However, 6000 mg is required at least and we only get 1000mg.

While Choline is not proven to offer any athletic improvements it can improve brain function when dosed correctly and thankfully we get the required 550mg.

Caffeine is a great stimulant that can effect the CNS which controls muscle and heart stimulation.

Synephrie can help you burn through fat instead of using carbs when exercising.

Higenamine also acts as a fat burner. Plus acts like a stimulant such as Caffeine.

Yohimbe is also a powerful stimulant. Yet, it is not without it’s issues.

How Did It Feel?

To be blunt, this had no positive effect on me at all.

I felt no benefit whatsoever.

I would not recommend this at all.

Plus it made me feel a little bit bloated regardless of how tasty it was.



There’s not many ingredients and is a bit under dosed compared to the best.

A proprietary blend which hides the exact amount of each ingredient contained is also present.

More importantly 6 of the 11 ingredients are not proven to be effective in offering either athletic/performance benefits or for increase brain function.

That’s almost 50% being ineffective.

Furthermore, Citrulline is massively under-dosed to be effective. In fact it is short of 5000mg – that’s a huge deficit!

While Yohimbe is a powerful stimulant and fat burning ingredient, it can cause such a lot of health issues I am always wary of trying a supplement which contains it.

Ronnie Coleman Signature Series YEAH BUDDY Extreme Energy Pre Workout Review Conclusion:

I have experienced another product from the Ronnie Coleman Signature Series almost 2 years ago and I was not impressed with that testosterone booster.

As with that product I am not impressed with this pre workout from Ronnie Coleman either.

Being such a large figure in the sport it would be a given that whatever product were to be released under his name would be the most effective and powerful.

However, here we are, with a pre workout that is a low dose, ingredients that are not dosed adequately, many that are not proven to offer any benefit and even 1 that is potentially dangerous.

On the flip side it tastes wonderful…not really a good enough reason to buy it and use it though.

There is a better product than this that will get you fired up and cause hell in your chosen sport but this is a total disaster.
