TestoFuel vs Invictus Alpha Boost

Two T boosters go to war today but who will emerge the victor in our TestoFuel vs Invictus Alpha Boost review?

Both products have built up a reputation and we are giving them a chance to show the other one up. Only one can be our winner today, so what does it need to do to impress?

The following is the minimum we expect:

  • More Strength
  • Enhanced Libido
  • Elevated Mood
  • Increased Energy

Anything less than this will not do, we expect the best as usual.

TestoFuel is one of the UK’s favorite supplements and Invictus Alpha Boost sells well on Amazon. Time to take a look at who is behind each product.

TestoFuel vs Invictus Alpha Boost: Who Makes These Testosterone Boosters?

Roar AmbitionTestoFuel Review

The UK based company behind TestoFuel are Roar Ambition.

They do customer service really well. They have a 90-day money back guarantee which we always like to see. On top of this, they review and amend their ingredients and dosages regularly. This means the consumer is always getting the most up to date version.

If endorsements are your thing, then theirs are impressive. None other than former Mr. Universe Robby Robinson puts his name to this product. For a guy in his 70’s, it’s pretty impressive stuff.

Roar Ambition also makes the popular fat burner Instant Knockout. This is endorsed by UFC fighter Diego Sanchez who uses it to make weight before a fight.

They always use 100% natural ingredients and use FDA approved facilities.

A good start.

Invictus Labsinvictus-alpha-boost

The US-based company behind Invictus Alpha Boost are Invictus Labs.

They also use FDA approved facilities and make their products in the USA to GMP certifications. Much like Roar Ambition, they also use natural ingredient which we like to see.

They actually give away bottles of their stuff. This seems a little desperate to us. Sure, it’s a competitive market but this seems a bit much.

You can’t actually buy their products from their own website. Any link just takes you through to Amazon. This makes it easy to sell but some might find this a little unprofessional.

When buying from Amazon, you have to rely on different types of money back guarantees.

We tried to find more, but their website doesn’t give a lot away. Maybe it’s best to move on now.

TestoFuel vs Invictus Alpha Boost Ingredients

Now the important part and where we can really separate the two T boosters.

There is good and bad news. The good is that TestoFuel does not have any proprietary blends. The bad news is that Invictus Alpha Boost has included a blend that covers all but one ingredient.

This means we don’t get to see the dosages which is a real big disappointment. How are you supposed to know if it is high enough for it to be effective or not?

Also, why would a company not boast about their dosages if they were an optimal amount?

With no mutual ingredients, let’s get straight into what they have on offer.


Vitamin D3

Possibly the most important of all T boosters.

Low D3 has been linked to low T for some time and the fact that we actually create our own should be a good thing. The problem is a deficiency in D3 is one of the most common in the western diet.

Our bodies create their own when our skin is exposed to direct sunlight. Clearly, we’re not getting enough rays.

For better sexual health, D3 is also important.

At 5,000 IU TestoFuel have included an amazing amount of a great ingredient, An optimal dosage to start us off.

Vitamin K2

A clever inclusion.

This is because many consider it to be important to take K2 when using Vitamin D3. This is to prevent the calcification of the arteries. In fact, Examine.com states that taking the two together actually increases the effects of each.

K2 is the version that can be better absorbed so it will get to work faster as well.

At 180 mcg, there is enough to get you what you need.

Vitamin B6

Another clever idea.

This time because B6 gets your body to stimulate androgen receptors. This then encourages your testes to create more T.

It is also well known for reducing the amount of estrogen you have. This is by ensuring the Sex Hormone Binding Globulin is less effective. This is what sticks to your T and makes it unavailable for use.

The opposite of what you need so anything like B6 that works against it frees up your testosterone.

5 mg here is all you need.


More of the good ingredients that inhibit SHBG. This is another then that will get your T on the rise.

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

You can’t argue with the studies and this is what we’re after. Ingredients backed by science.

There is 200 mg in TestoFuel which makes it another optimal dosage.


Up there with the best and certainly one of the most important T boosters.

In fact, our bodies cannot create more testosterone without it.

Zinc is great as it stimulates the luteinizing hormone. This communicates with the testes to create and release more testosterone.

It also stops our bodies from depleting T levels so fast during intense workouts. This saves more of the good stuff for later.

There is 10 mg of Zinc in TestoFuel. However, it also contains Oyster Extract which is high in Zinc so it is safe to assume there is even more.

D-Aspartic Acid

TestoFuel is reeling out the great ingredients.

DAA is an excellent ingredient as it increases the level of the Human Growth Hormone in the body. Not done yet it also acts fast in terms of boosting T. Studies out there have shown it can increase testosterone levels by 50% in under 2 weeks.

Also, it is another ingredient good for stimulating the luteinizing hormone. It even makes sure you use your protein better in terms of getting those gains.

You really want an optimal dosage of DAA and that’s just what TestoFuel gives you. 2,300 mg is another excellent amount.


A tradition ingredient used as a libido enhancer. This is another base covered in terms of what a good T booster should do.

It is even known to bring your testosterone up to a healthy level as well as working as an aromatase inhibitor. Increasing T whilst decreasing estrogen is what we’re after.

It is even thought to have muscle building potential. You’ll get a nice boost with the 100 mg dosage.

Siberian Ginseng

A stress reliever, making it another very good inclusion.

Since stress is a known killer of your T, anything that can help the body to deal with the effects is a welcome addition.

A safe ingredient that is also good for reducing prolactin levels. This is another positive trait as men with high prolactin tend to have low T.

With 100 mg in TestoFuel, it’s another good boost.

Oyster Extract

As mentioned earlier, this is another good idea as it is high in Zinc.

Anyone excellent inclusion as you will find it hard to put on more muscle so it’s great that they have included Oyster Extract.

With so many trace elements great for general good health, the 100 mg will do a lot of good.

Invictus Alpha Boost

Calcium (as Calcium Carbonate)

The only ingredient not in the proprietary blend for some reason.

There are some that suggest it can help aid the testosterone boosting effects of exercise One study trialed T levels before and after the supplementation of calcium and found it to have a positive effect.

The main benefit is to your overall health. In terms of effective testosterone boosting it isn’t exactly heralded. It seems every reference we find is to the previously mentioned study, we’d like to see some more to back it up.

It doesn’t matter anyway as there is more calcium in half a cup of milk than the 44.28 mg included.

Horny Goat Weed

No joke, it’s an actual ingredient.

In fact, it isn’t the worst in this T booster. If you read Examine.com, they advise it is a traditional medicine that is also a famous aphrodisiac. This is what we like, a libido enhancer.

Examine also advice that it has shown promise in animal research, boosting their T levels. With more research on humans, it could be a decent inclusion. Still, extra libido is never a bad thing.

Since it is in the proprietary blend, we have no idea if there is enough for there to be the desired effect.

Tongkat Ali

An ingredient that is a little frustrating.

There are too many maybes associated with Tongkat Ali. It might be good at inhibiting SHBG. We like anything that can do this but as you have seen with TestoFuel, there are plenty of ingredients that are proven to do this.

There is also the possibility that it can help to reduce the effects of stress. Again, there are proven ingredients that will definitely do this. Cortisol levels need to be low for your T to thrive.

The last maybe is that it might be a good aphrodisiac and increase sperm count – maybes maybes maybes.

Is it effective here? We don’t know – the proprietary blend stops us from finding out.

Saw Palmetto Extract

Derived from the fruit of this plant, it may be useful to a T booster.

According to WebMD, it could stop T from being converted to dihydrotestosterone (DHT). This is good news because DHT is linked to causing baldness.

Sure it is is another that has maybes attached to it, but if it can also aid sexual function like it is thought to, we could be convinced.

The problem once again is the proprietary blend stopping us from knowing how much Invictus Alpha Boost has included.

Orchic Substance

Ok, here we go…. Orchic Substance is made from Cattle testicles.

According to WebMD, whilst marketers imply that orchic extracts are a good source of testosterone, there is currently no evidence to support this claim.

Not great if you’re consuming cow balls for no reason. Definitely not one for vegetarians then.

We don’t know what a good dosage of this ingredient is as there isn’t a lot of research for it. Just as well that it is in the proprietary blend then.

Wild Yam Extract

We’re not impressed by this one. Most sources suggest that more research is needed to back it up as a useful ingredient.

Why has it been included then? Well, it is thought by some to have effects that are similar to DHEA. This is a banned substance in many sporting organizations.

You could say that at least DHEA effects your T levels. Going by the evidence, there isn’t much out there to suggest that Wild Yam Extract does.

As the compound diosgenin is found in Wild Yam Extract it is good for bone health. Some sources even say it is a good source of estrogen. Although this sounds concerning, it shouldn’t be. Your body can’t actually convert it to estrogen.


This is often used for medicinal purposes. You are otherwise going to find this added as a flavoring agent to soft drinks and foods.

WebMD says that some supplements out there claim that chemicals (sterols) in this ingredient can be converted to anabolic steroids like testosterone. But this is actually a false claim.

Not a great inclusion then and no dosage is given of course.

Nettle Extract

A good ingredient, it’s been a while for this product.

Found in numerous T boosters due to its ability to work as an aromatase inhibitor. It will stop your body from turning testosterone into estrogen.

We want to see around 1 – 300 mg of it. We don’t know if this product achieves this though.


Maybe the best ingredient in Invictus Alpha Boost and saved for last.

This mineral helps the other ingredients that are important for T boosting. It is also thought to be great for preventing SHBG from being as effective.

A good overall T booster that this product has been crying out for.

The problem is we don’t know if there is enough of it. The blend could be made up of loads of Tongkat Ali for all we know!

TestoFuel vs Invictus Alpha Boost Side Effects

The good news is that neither product seems to have anything in there that could cause harm.

TestoFuel have provided all their dosages and everything seems completely fine.

The concern would be the proprietary blend in Invictus Alpha Boost but it doesn’t seem overly potent. As always check the labels in case of allergies.
