Having reviews 100’s of products we have seen many that make it difficult on themselves. We don’t want unproven ingredients or ones that are underdosed. To be a top product, you need to have it all.

  • More Strength

Two products with increasing reputations and reach, time to see what they have to offer.

TestoFuel vs MD Certified Natural Testosterone Booster: Who Makes These Products?

Roar AmbitionTestoFuel Review

The team behind TestoFuel are UK based Roar Ambition.

The ship directly from the UK and USA and have a great reputation online.

This is reflected in the number of testimonials you can find. So many people are taking to the net to show their before and after profiles.

They have a generous money back guarantee and amend their ingredients and dosages regularly. This means you are getting the best possible version at all times.

If you are into endorsements then theirs are pretty impressive. None other than former Mr. Universe Robby Robinson puts his name to TestoFuel.

Roar ambition also makes a fat burner called Instant Knockout. This is endorsed by UFC fighter Diego Sanchez who uses it to make weight before a bout.

Lean Nutraceuticals MD-Certified-Natural-Testosterone-Booster

The company that makes MD Certified Natural Testosterone Booster are Lean Nutraceuticals.

They make their products in the USA to GMP and FDA certifications.

There is a lot of talk from them about the potency of their products and there is a money back guarantee.

Often, they collaborate with Jeffrey Hendricks who is a biochemist. He uses his expertise to contribute towards some of their products.

They appear to be a large company that also makes weight loss supplements and immune booster products. There don’t appear to be any endorsements on their site.

TestoFuel vs MD Certified Natural Testosterone Booster Ingredients

The early signs are good for both. No proprietary blends to worry about. We are getting all the dosage information so we can really compare the two of them effectively.

Mutual Ingredients


A very good start by both.

You cannot create more T without Zinc so this and the fact that many of us are deficient makes it a good inclusion.

Zinc is good for stimulating the luteinizing hormone. This communicates with the testes to create and release more testosterone. It is also good for ensuring your body does not deplete T levels so much during an intense workout.

The 25 mg in MD Certified is an optimal amount. TestoFuel has gone for 10 mg but has also included Oyster Extract, which is high in Zinc. The two dosages are likely to be similar and will both get your T on the rise.


A decent traditional ingredient.

Used in traditional medicine it is a well-known libido enhancer. It also has other benefits for a T booster in that it is an aromatase inhibitor.

This results in lower estrogen, making room for your T to thrive. We like it because it is backed by various studies and it can also stabilize blood sugar levels. This is important for a T booster because when insulin fluctuates it can be disruptive for testosterone.

Fenugreek might also be good for building muscle as well as post-workout recovery.

TestoFuel have given us a top-up of 100 mg, MD Certified Natural Testosterone Booster has given it a lot of room with 600 mg, an effective dosage.

D-Aspartic Acid

One of the best ingredients for boosting T.

Various studies have shown how effective and fast working it can be. One, in particular, is often cited as it showed that DAA raised T levels by 50% in under 2 weeks!

It is another that stimulates the luteinizing hormone and it also increases the Human Growth hormone levels.

On top of all this, it puts your protein to work where you want it – your gains.

Such a good ingredient gets the full dosage in TestoFuel. 2,300 mg is a great and optimal amount from them.

Can MD Certified Natural Testosterone Booster do the same? No! The tiny 50mg is nowhere near enough to get us what we need.

Individual Ingredients


Vitamin D3

One of the most important and best T booster ingredients available.

D3 is great because low levels of it are often linked to low testosterone. Supplementing it is important as so many of us in the western world are deficient.

This is a shame because our bodies create their own D3 when our skin is exposed to direct sunlight. Clearly, we aren’t getting the rays we need.

TestoFuel has gone for a big 5,000 IU – a great amount that will really get your T levels up.

Vitamin K2

Often included where D3 is for a reason.

K2 stops the calcification of the arteries that can occur when taking D3. Examine.com advise taking both together actually increases the effects of each.

K2 is the version of the K vitamin that is fastest to be absorbed by the body and the 180 mcg here is a good amount.

Vitamin B6

Getting your testes to create more T is an important trait and B6 does just this by stimulating androgen receptors.

It inhibits the Sex Hormone Binding Globulin which means the testosterone in your body that is bound and unavailable can be put to use.

It can also help to support the immune system and help you to break proteins down. An ingredient your body cannot store so keeping it topped up is important.

The 5 mg included is a good amount once again.


Another excellent inclusion from TestoFuel.

Also, another that inhibits the SHBG (the more of these the better).

The Journal of Pharmaceutical and Biomedical Analysis suggests that men with more magnesium in their blood tend to have higher levels of free T.

It is also known to help the body deal with the effects of aging and exercise.

TestoFuel is giving us 200 mg, an optimal amount once more.


The version in TestoFuel is Siberian Ginseng.

It seems the traditional ingredients are the ones that are the most reliable at times.

Ginseng helps your body to cope with the effects of stress. This means it won’t impact you as much.

There is a study that details how rats with 5% Panax Ginseng in their diet for 60 days have shown significantly increased blood testosterone levels. We prefer to see human trials, but the potential is there for this.

A proven libido booster it will also keep prolactin down. People with higher prolactin often have lower T levels.

The 100 mg in TestoFuel makes it another good boost.

Oyster Extract

The last of the ingredients from TestoFuel.

We touched on this earlier advising how it is high in Zinc. This combined with the various trace elements that have loads of great benefits for the body make it a good inclusion.

MD Certified Natural Testosterone Booster

Otherwise known as Vitamin B3, Examine.com says it as an essential B-vitamin. It also comments that a side effect of supplementation is increased insulin resistance and it only provides benefits to cardiovascular health if precautions are taken.

There are sources that say it is good for dealing with erectile dysfunction and is found in chicken and grains. However, you will need to consume a lot of both of these to get the amount of B3 needed for these benefits.

It is important for the transferring of fats and carbs into energy. This means you will get more energy for the gym as well as fat burning.

Not one for a T booster though, we want ingredients that are going to get our T on the rise.

Unfortunately, this isn’t the ingredient for that.

You are also going to need more than the dosage of 30 mg anyway.

Whey Protein Hydrolysate

Speaking of ingredients that are unnecessary in a T booster.

This protein source is a good ingredient for a bodybuilder but better off taken as a shake to ensure you are getting it when you need it.

Muscle recovery is a great thing to get some help with. We’d also like to get more sleep so why not sleep enhancers? (hopefully, the sarcasm is coming through there!)

You can include all the extra benefits you like but we’re after testosterone boosting ingredients.

Mucuna Pruriens

One of their better ingredients.

As there is more estrogen in our system the older we get, this is a good ingredient. It reduces estrogen and prolactin levels.

Examine.com says that it works against prolactins suppressive effect on libido and testosterone.

A good ingredient, the only problem is the dosage. We need much more than the 50 mg you are getting from this supplement for any effect to be felt.


Be wary of this ingredient.

Sure, it has been shown to boost your T and blocks the SHBG. It even keeps your blood in a more youthful state but is thought to work in a similar way to steroids. This is where the issues start.

This is what has resulted in various sporting organizations such as the NBA and NCAA banning it from use.

You cant even buy a supplement that contains DHEA in Canada as it is on the banned ingredients list.

If this affects you then you will want to check with your sporting organizations governing body before consuming.


One of the better ingredients here.

It brings out the best in other ingredients, more notably Magnesium.

It’s also another that inhibits SHBG. Examine.com shows you how much free testosterone Boron can provide. Boron = more free T.

The problem is the low dosage of 1 mg which will have little effect.

Tribulus Terrestris

An ingredient that is often included in T boosters but is only good for your libido.

Still, many supplements include it in their T boosting blends but Examine.com says it has been shown to be an effective libido enhancer. The problem is, this is also a resource that comments on its limited use for power output and testosterone enhancement (which it has repeatedly failed to do).

The 600 mg they are including here shows the faith they have in it.


An ingredient mostly linked to sexual health, it’s a decent idea.

It increases testicular blood flow which is good news for the health of your testicles. On top of this, it increases overall blood flow.

WebMD comments on how it converts into nitric oxide in the body. This causes blood vessels to open wider for improved blood flow.

Again though, you need at least 300 mg for it to really do anything. We’re only getting 100 mg in this supplement.

Horny Goat Weed

A good name, but an average ingredient.

Examine.com suggests that it is a traditional Chinese medicine and a well-known aphrodisiac.

It has been shown to increase T levels in research animals. We want to see proven ingredients backed by human trials really.

We only have half of what we need anyway in the 100 mg.


Often called Longjack it is a decent ingredient.

It is Examine.com that says it has a lot of backing to support its use as an aphrodisiac. Also, the same page also says there is a lack of evidence when it comes to T boosting but could be an effective anti-estrogen ingredient.

You need at least 200 mg as a start but once more, we’re getting 50 mg which will not help.

TestoFuel vs MD Certified Natural Testosterone Booster Side Effects

The good news is that neither product contains anything that should concern the user.

TestoFuel, in particular, has gone for proven T boosters at optimal and sensible dosages.

MD Certified Natural Testosterone Booster has included DHEA so be wary of this ingredient if you need to comply with any sporting organizations rules.

As always, check the label if you have any allergies.
