My Highmark Nutrition Oxy Shred Fat Burner Review

My Highmark Nutrition Oxy Shred Fat Burner Review First Look

I have just returned home after cycling from work.

This morning was quite chilly, but fuck me dead, I am sweating like a greasy pig at the moment. I’m uncomfortably warm.

However, I am on the mission to lose as much fat as I can before my vacation to Mexico.

I have had a lot of things going on in the background lately which has meant that my gym regime and cycling has suffered.

As a result, I do not feel quite as strong nor as cut as I would like.

So, tonight, I will be on the weights in my gym and I will be cycling more to and from work, plus come mid-May I will be mostly working from a more relaxed environment whereby cycling to work will be a less time sensitive task, plus I will no longer be face-to-face with clients so the need to have a freshly ironed shirt will be no more.

It is these small problems such as trying to get showered at work and look presentable plus other distractions and commitments that al conspire against your quest to build muscle and lose fat.

This is exactly where an effective fat burner can help.

Fat burners can give you that edge whereby you burn the extra calories required which help toward creating that deficit which can lead to fat loss.

Especially if you cannot commit to a really good and consistent cardio regime.

This fat burner supplement from High Mark looks the business in black with dashes of red and chrome. It looks purposeful and as a result, one would think it will have powerful effects.

However, will its bite be as loud as the bark?

What can a fat burner really do?

You may well be surprised actually.

The idea that an effective fat burner just magically makes your waist smaller is far from the truth.

However, only the effective fat burners contain a number of ingredients in correct doses that work harmoniously and through a number of outcomes help you lose fat mass, not muscle.

Their benefits include, but are not limited to:

  • Increase energy – This will help you be more active and stimulate you for effective workouts
  • Thermogenic – These ingredients will increase the temperature of your core which increases calorie expenditure
  • Appetite control – The ability to feel fuller and not to fall for sweet, calorie laden treats

As a result I tend to supplement my exercise regime with a fat burner supplement.

I have found Instant Knockout to offer the best results and as a result I try to use that daily.button-4

OxyShred Ingredients: The Science

Green Tea

A well known to have many powerful health benefits. Clinical studies suggest that green tea extract may boost metabolism and help burn fat.

One study found that the combination of green tea and caffeine improved weight loss and maintenance in people who were overweight and moderately obese.

Some researchers think that substances in green tea known as catechins are responsible for the herb’s fat-burning effect.

It has been shown to help lose almost 5% body weight over a three month period.

Green tea extract is found in many a good fat burning supplement.

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.


Related to Yohimbine, Yohimbe is a powerful stimulant and used to increase fat loss as well as assist with erectile dysfunction.

Yohimbe 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.


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.


Tyrosine is taken for depression, attention deficit disorder (ADD), attention deficit-hyperactivity disorder (ADHD), the inability to stay awake (narcolepsy), and improving alertness following sleep deprivation.

It is also used for stress, Parkinson’s disease, Alzheimer’s disease, chronic fatigue syndrome(CFS).

Fursultiamine (Thiamine tetrahydrofurfuryl disulfide)

This improves energy metabolism when fatigued.

Rasberry Ketone

Whilst touted as a miracle weight loss supplement and sometimes for lean muscle mass it is important to keep in mind that there is no reliable scientific evidence that it improves weight loss when taken by people.


This is a soluble, fermentable, and highly viscous dietary fiber derived from the root of the elephant yam or konjac plant, which is native to Asia.

Preliminary evidence suggests that Glucomannan can promote weight loss.

This is found in the #1 fat burner, Instant Knockout.

Kola (Centella asiatica)

A legendary plant in China and Indonesia that as been used for many ailments, and may be good for syphilis, however, nothing to do with reducing fat.


Up to two pills to be taken in 24 hours.

It is good to spread out the dose across the course of the day to ensure our body has a constant supply of ingredients to process rather than peaks and troughs.

If you get too much of certain ingredients, that what the body doesn’t need at the time will be wasted and you will not feel the benefit.

Therefore, if you have a massive dose of Magnesium for instance yet your body is still processing and utilizing Magnesium from a meal you’ve recently had it will only use what is required.

What the body doesn’t require at the time will let it pass. Thus, a higher chance of waste and less benefits.

It is better to have a continued trickle effect.

This results in a daily dose just a shade over 994mg which is low when compared to competitors.




According to the retail figures, this is a big selling fat burner, and I want to establish what makes it such a success.

Well, looking at this ingredient profile there seems to be a few hints to its popularity.

So let’s look at these in more detail to see what all the fuss is about.

Green Tea is a proven ingredient that we see in all of the better fat burner supplements on the market.

Caffeine not only increase focus, energy but helps with recovery so you’re not aching as much which could put you off that extra session in the gym.

Tyrosine helps fight off fatigue and improves concentration, this way you can get off the sofa and focus on that set of squats.

Glucomannan is found in the best fat burner supplements such as Instant Knockout, for good reason.

Glucomannan is seen to promote fat loss when studied for research.

Fursultiamine is an ingredient that we do not come across very often. However, it should feature more if the science is anything to go by because it increases energy metabolism through fatigue.

So, all-in-all, five ingredients worthy of a shout for helping you lose excess fat by burning extra calories or contributing towards increased calorie expenditure.

So, is there anything wrong with it..? Read on…



Well, yes, there’s plenty wrong with this.


Well, let us for a second remember that this supplement consists of three proprietary blends.

If you are not familiar with a proprietary blend, watch the video below of me in my old garage gym.

If you have skipped the video, a proprietary blend essentially means that although we know which ingredients are included in the supplement, we have no idea of the individual breakdown of each ingredient.

Legally, the supplement company could literally include just trace amounts per ingredient and the rest being a low cost filler.

Just to repeat that, this is completely legal.

Then there’s the ingredients that are not proven to offer any benefit. These include:

Kola has no evidence to support its use as a fat cutting ingredient.

Raspberry Ketones were made popular by a TV show which claimed that they were an effective fat loss ingredient, this was proven to be incorrect.

Yohimbe, above anything can actually be quite dangerous. It is a powerful stimulant that can raise blood pressure and even cause a stroke potentially.

To add to this, there’s no real proof that it can alter body composition.

That is a lot of risk for no guaranteed reward.

Phenylethylamine is another addition that seems rather fruitless considering there’s no scientific evidence to suggest that it can increase athletic performance or even treat the markers of depression.

Then, there’s a number of ingredients that are missing, yet are proven to be beneficial and would like to have seen included, too. 

These include:

  • Zinc
  • Magnesium
  • Green Coffee extract
  • Vitamin C
  • B vitamins
  • Cayenne
  • Synephrine

Then, let’s not forget that the daily dose is low, and the dose schedule not optimal.

Looking back over the ingredients I think it is also fair to say that there’s a 60% – 40% split of good, effective ingredients to those that are lacking.

My Highmark Nutrition Oxy Shred Fat Burner Review Conclusion

The problem with this supplement is that its the excellent components are overshadowed by those that offer no clinical proof.

There’s almost as many unproven ingredients as there are proven with 40% of the ingredients offering no benefit.

This then is coupled with a proprietary blend which conceals the exact dose per ingredient included. We are well and truly kept in the dark.

Overall, this doesn’t offer much confidence nor much in the way of performance.

Anything else worth adding to this review..?

With hidden ingredient doses, a low overall dose and almost as many unproven ingredients as those that can help us lose fat mass, I’m heading over to choose between the fat burners that offer real results.
