Defiance Labs Pyrolyze v3 Review

Defiance Labs Pyrolyze is a fat burner that’s supposed to set fire to your metabolism. Helping your body burn away extra fat through the day.

Pyrolyze looks and feels like a great product, there’s a solid feeling to the bottle and a full count of the capsules inside.

Generally you need a fat burner to provide 3 areas of support.

  1. Increased Metabolism – Burn fat through the day
  2. Appetite Suppression – Take on less calories
  3. Energy Increase – Feel happier, more energized

It looks like Pyrolyze uses it’s blend of ingredients (both natural and synthesised) to hit all these important areas.

Annoyingly Defiance Labs have opted to use a proprietary blend in this product. To learn more, read below:

Defiance Labs Pyrolyze v3 Core Ingredients

Pyrolyze contains a 2 proprietary blends that make up 787mg and 320mg of ingredients in the capsules.

The first blends focus is on amino acids and also fat burning herbs. This is designed to activate your metabolism and give you more energy through the day.

You should also be very wary of proprietary blends.

Generally while most supplements that use them are ok, some can actually have harmful side effects if ingredients are dosed wrong.

Defiance Labs Pyrolyze v3 Ingredients


Caffeine is a staple supplement to modern day life. It is a highly effective stimulant in how it boosts the metabolism, mobilises fat to be used as energy and suppresses appetite.
As well as this it can boost the effects of other metabolism boosting products, such as green tea or bitter orange.
It has long been used by athletes, and non-athletes alike, in order to increase alertness, endurance and longevity.
This is essential for a fat burner. You need around 250mg-300mg dosed evenly through the day for best results.


This is a caffeine molecule similar to caffeine. However where theacrine differs is it can raise levels of dopamine too, further enhancing the mental energy you get from this ingredient.

Generally doses range from 50mg-300mg with 300mg being more effective after longer periods of supplementation.



Also known as bitter orange or Citrus Aurantium.
Synephrine is the compound found within the unripe fruit of Citrus Aurantium. It has been shown to have the same effects as ephedra or ephedrine, without being able to be converted to methamphetamines.
It is shown to increase metabolic rate, fat break down, thermogenesis and also shown to decrease a person’s appetite.
Due to the similarities however, it can also cause similar side effects. Especially when combined with other stimulants.

Cayenne Pepper

Cayenne Pepper is a species of pepper native to the Americas. It is a key element in various cuisines but is now often used as a supplement.
Cayenne Pepper contains capsaicin which is known for its “warming effect.” It is known for its positive effects on healthy blood circulation throughout the body. This ingredient has been proven to burn calories in fat burners. 100mg through the day is an ideal amount.


This will aid with focus and also take the edge off stimulants, allowing the energy to be channeled and also keeping cortisol (stress hormone) levels lower.

You want 200mg+ for this to be truly effective.


This is the pre cursor to serotonin and can help elevate mood over time.

This does have to be supplemented for extended periods for full effect but can result in better periods of rest.

Defiance Labs Pyrolyze v3 Dose

You need around 2 capsules, sometimes 3 to get the best results from Defiance Labs Pyrolyze.

It’s worth remembering that this product isn’t a standard fat burner though and borrows more from a pre workout than anything else.

Generally you’ll get the best results from this serving as a pre workout supplement.

Whilst we can’t comment on the individual doses of certain ingredients, it looks fairly under dosed given that some amino acids present require a 300mg+ dose on their own.

Defiance Labs Pyrolyze v3 Side Effects

The side effects you get from this product could prove a little risky.

This is because Defiance Labs have chosen to include Synephrine inside this fat burner.

Synephrine, whilst potentially causing unwanted side effects on its own, is far more likely to affect you if its combined with caffeine.

The side effects reported by this combination are generally headaches, nausea and anxiety.

Test your tolerance before commiting to a full serving of Pyrolyze.

Defiance Labs Pyrolyze v3 Review Conclusion

This is a very hit and miss product.

You’ll get some good energy from the doses of stimulants but ultimately the propretiary blend means you literally cannot see what you are taking.

Combining this with a blend that contains both caffeine and synephrine and you are potentially setting yourself up for a rough ride, as opposed to a fat burner than can be supplemented for long periods.
