Musclewerks D-Fine8

Musclewerks D-Fine8 Overview

What you need to know about Musclewerks D-Fine8

Musclewerks D-Fine 8 is a pre-workout supplement in a powdered form that you use to make an energy drink by mixing half a teaspoon sized scoop of powder to water. There are 18 flavours to choose from and the product packaging has recently been updated. The version here is the new version which is packaged in a plain blue container bearing the Musclewerks logo.

D-Fine 8 is strong in stimulants, with caffeine the principle component and although you may notice an energy buzz from this, it is extremely expensive for a caffeine supplement. Worryingly, other ingredients include Higenamine and Citrus Aurantium in unknown quantities so if you take part in competitive sport, this supplement could get you banned for doping. You should avoid if you have any medical issues, especially concerning heart or blood pressure.

What are the side effects of Musclewerks D-Fine8?

Musclewerks D-Fine 8 may cause side effects. Many of these are related to stimulants and include jitteriness, anxiety, insomnia, increased heart rate, palpitations, increased blood pressure levels, vomiting, nausea, loss of appetite, heartburn, dizziness, and mood swings.

Dandelion extract is a diuretic, so increases the amount you urinate.

Speak to your physician before using if you have an underlying condition, especially if it is related to heart or blood pressure or is a mental health issue. This supplement may cause interactions with prescription medication, so seek trained medical advice before use.

How much does Musclewerks D-Fine8 cost?

Musclewerks D-Fine 8 is expensive. Buy from the official Musclewerks Inc website and it costs $54.99 for a tub which contains 60 x 1 scoop servings. You are advised that you can take 4 scoops a day making this only 15 days supply.

You can also buy from Musclewerks via Amazon where it costs $55.99 per tub.

Musclewerks D-Fine 8 is also on sale from independent retailers and eBay, so you may be able to shop around for the price. The older versions of this supplement are packaged in containers displaying a picture of the various flavours and are usually around $10 cheaper than this newest version.

Musclewerks D-Fine8 Key Features

D-Fine 8 is a pre-workout supplement. It is in powdered form so to use you just add to water, mix, and drink and according to the advertising, this will help you enhance your energy levels, reduce appetite, and generally get more out of your workout.

The supplement has a wide choice of flavours. There are 18 in total and we get that Bada Bing Cherry probably tastes of cherry and Hawaiian punch is probably fruity, but Electric Unicorn? In fairness, this is the only really weird name; most of the flavours are fairly descriptive and include Mango Orange, Pink Lemonade, and Strawberryade.

All the flavours look to be very sweet. There was a sugar-free version of this supplement called Musclewerks D-Fine8 Zero, but this seems to be no longer available.

D-Fine 8 contains an energy blend composed of different forms of caffeine. But the bulk of the supplement is provided by 2000mg of the Focus and Thermo Blend. This contains a blend of ingredients in unknown quantities, including Green Tea extract, N Acetyl Tyrosine, Dandelion Root extract, Nandina, and Citrus Aurantium. Some of these are known for side effects, so it would have been useful to know the precise quantities in order to assess strength.

Check out the ingredients tab and the side effects tab to find out more.

Musclewerks D-Fine8 may be smaller than you think. The tub is only 3.75 (9.5cm) inches high and the 2.35g serving size is equal to about half a teaspoon, although it does come with a measuring scoop.

Musclewerks is a US based company. The only physical address we can find is a PO Box in Newport Beach California. However, you can contact the company via email.

Musclewerks supplements are on sale via the official website, and it is also available on Amazon and eBay. The company also uses affiliate selling (where you advertise a product and get paid when somebody buys something via your link). Musclewerks is also looking for retailers, and you can buy supplements from many independent retailers including the Vitamin Shoppe and Elite Supps.

Does Musclewerks D-Fine8 work?

The advertising claims this supplement is trusted, used, and recommended by fitness professionals. This sounds impressive but if professionals really used this supplement, it would get them banned for doping because it contains a stimulant called Higenamine banned by WADA, and also Citrus Aurantium which is banned by the National Collegiate Athletic Association (NCAA).

D-Fine 8 contains a blend of caffeine, including caffeine anhydrous which is a strong crystallised form of caffeine that can be up to 28 times stronger than ordinary caffeine. This combined with the other stimulants may lead to increased heart rate and blood pressure.

In our opinion, Musclewerks D-Fine 8 is going to have a strong stimulant effect and if you feel wired and jittery, you will probably not feel hungry. However, this supplement does not look at all safe and could be dangerous for many users.

The most popular appetite suppressant in 2020 is Phentatrim.

Its ingredients are scientifically proven to aid weight loss and you are covered by a full 60-day money-back guarantee from a trusted company, making Phentatrim a very popular choice in the diet world.

Phentatrim is the best thing to hit the supplement market in a long time, with thousands of customers already seeing the benefits. That’s why it's our editor's top pick.

Musclewerks D-Fine8 Ingredients

Serving size is equal to 1.25 g scoop of powder.

• Vitamin B6 (1.7mg): Important for brain health and the nervous system, B6 is involved in many processes in the body, mainly concerned with the metabolism of proteins. The RDA is 1.7mg but higher servings are well tolerated.

Energy Blend (150mg):

• Caffeine Anhydrous: This type of caffeine is often used in supplements and is much stronger that the natural caffeine present in coffee so this will feel much stronger than the 150mg implies.
• Caffeine Citrate: This is a drug made by combining caffeine anhydrous with citric acid and sodium citrate. It is most commonly used to treat breathing problems in premature babies. When used in supplements like this it may help caffeine enter the bloodstream within 30 minutes – much faster than other forms of caffeine. Source
• Di-Caffeine Malate: Blend of caffeine and malic acid. It provides the same energy boost as caffeine but may have a calming effect upon the digestive system.

Focus and Thermo Blend (2000mg):

• N Acetyl L Tyrosine: Soluble form of L Tyrosine, an amino acid, which you can obtain through diet if you eat meat and cheese. In supplement form, it is believed to help training and is popular with bodybuilders for this reason. It is believed to stimulate brain chemicals serotonin and dopamine and is sometimes taken to treat depression. Research suggests that taking 150mg will improve alertness after missing a night’s sleep for around three hours
• Citrate: Acid compound found in citrus fruits and important for the metabolism. Citrate may help reduce acidity in urine.
• Green Tea Extract: Clinical research has found that green tea has proven health benefits, and the antioxidants (ECGC epigallocatechin-3-gallate and polyphenols) found to have anti-obesity and fat burning properties because of the effects upon the metabolism. Clinical research suggests it combines well with caffeine. Source
• Nandina Domestica Extract: Better known as Heavenly or Sacred Bamboo and a popular garden plant, Nandina contains a natural chemical called Higenamine which is a stimulant that increases heart rate and muscle contractions. Higenamine is banned by the World Doping Agency. Source
• Dandelion Root Extract: Well known garden weed and a natural diuretic. So it will increase urination.
• Cocoa Extract from Theobroma Cocoa: Latin name for the cocoa tree. The source of chocolate! Cocoa can have health benefits. It helps widen arteries so may help reduce blood pressure.
• Taurine: Best known as an ingredient of energy drinks like Red Bull, Taurine is present in the body in brain, eyes, blood, and heart, as well as derived from dietary protein, especially red meat and fish. It has benefits to heart health and may improve endurance.
• 6 Paradol: Flavanoid present in ginger and grains of paradise. Testing on animals identified it as a powerful antioxidant.
• Citrus Aurantium Extract: Citrus Aurantium contains a chemical called synephrine which has been proven to increase the metabolism and so may aid weight loss. However, there are numerous concerns about its safety especially as it increases heart rate and blood pressure if taken in high amounts. Source

Other ingredients: Natural and Artificial flavours, Silicon Dioxide, Sucralose.

Watchdog Verdict

Musclewerks D-Fine 8 seems overpriced. It is important to remember that although the tub looks big in the advertising, serving size is only around half a teaspoon and the total size of the container is only 3.75 inches tall. We can imagine that some customers will be disappointed when they receive their product through the mail and in all truth, it does not look like much for $55.00.

In addition, this supplement will not last very long. Although the advertising states it contains 60 servings, you are advised to take up to 4 (or even 5) servings a day so we think that for just 15 days supply Musclewerks D-Fine 8 is extremely pricy.

Finally, there is no proof that any professional sports people have ever taken this supplement. If they did, it could see them fail a doping test as it contains Higenamine which is banned by WADA and Citrus Aurantium, banned by the NCCA.

In our opinion, this supplement will work in much the same way as an ordinary energy drink with the added disadvantages of an increased risk of side effects, disqualification from sports, and all at much more cost.

We don’t recommend Musclewerks D-Fine 8 to the Watchdog readers.
