S.A.N Free T vs TestoFuel Comparison

When you discover a new testosterone booster, you always like to find out how it compares to your most reliable. Today we have S.A.N Free T vs TestoFuel to compare.

That’s exactly what we have here. S.A.N Free T is a product that we didn’t know a lot about until recently, when we found out about it the first thing we wondered was ‘how does this compare to the likes of TestoFuel (one of the best products on the market)?’

There’s a lot to like here on first impressions, we know that TestoFuel contains a large amount of the top testosterone boosters, and many of them at optimal dosages, that’s why it is so incredibly popular.

We were pleasantly surprised to see the first few ingredients on the S.A.N Free T label contained some top T boosters.

Without giving too much away, this alone won’t be enough. Which of these T boosters will be safest and which will have the most impressive dosages of the most beneficial T boosters?

Any testosterone booster worth considering needs to do at least some of the following:

  • Boost Testosterone levels
  • Enhance Strength
  • Increase Libido
  • Be Safe
  • Enhance Recovery
  • Suppress Estrogen

Time to get into it then.

S.A.N Free T vs TestoFuel: Who Makes These T-Boosters?

Roar Ambition

Here we have the people behind TestoFuel. Their products are used by some of the world’s top performance athletes. They ship throughout the world from both the USA as well as the UK.

One of the most pleasing things about them is that they update their ingredients every few months. A sign of a real quality company it is obvious they want to make the customer know they are getting the very best version of their product possible.

They only use completely natural products which is one of the real plus points about Roar Ambition. This builds trust and if they were to bring out a new product. No matter what area it was in, we would pay attention.

Their products are put together in facilities that are approved by both the GMP, as well as the FDA. Impressive stuff.

S.A.N Nutrition

The people behind S.A.N Free T are S.A.N Nutrition. Since we didn’t know a lot about them we had to do our research online, and it doesn’t take long to search their site and find out they have been creating supplements since 1996 – talk about experience.

Their site definitely shows they have a passion for what they do, and their ambassadors include some pro bodybuilders as well as many fitness pros.

Their products are created in the USA and adhere to the GMP regulations. They have a wide range of products on their site and even sell merchandise with their branding on.

S.A.N Free T vs TestoFuel Ingredients

Now, this is where we get into the thick of it. A great start for both in that neither product contains any proprietary blends. This is always an approach we prefer to see. Proprietary blends make it difficult to find out if a supplement is truly effective, and even safe.

A blend like this can mean the company do not disclose the dosages of all the ingredients, since a blend contains numerous ingredients. A company only gives the total dosage of all the ingredients. This is difficult for the user as we all want to know what goes into a product.

But no such problem here, the first thing to do then, is look at…

Mutual Ingredients

D-Aspartic Acid

A great sign right from the start, this is known to be an excellent testosterone booster due to it’s ability to ability to raise them by almost 50% over a two week period. There aren’t many natural testosterone booster ingredients that are as effective.

One of the ways it is good for your T levels is that it helps your brain to release the luteinizing hormone, this in turn encourages your testes to create more testosterone.

S.A.N Free T has done well and Contains the optimum amount of 3,000 mg, TestoFuel contains a decent amount at 2,300 mg. Both will be effective but this gives S.A.N a very slight edge early on.

Vitamin D3

Another top T booster, both products are looking good at an initial glance. This is deficient in a lot of western diets. That’s actually quite a shame and a sign of the times since we produce our own D3 when our skin is exposed to sunlight. To be deficient it means we are not getting outside enough.

Low levels of Vitamin D3 often mean the person has low testosterone levels as well. A man’s sexual health is directly linked to Vitamin D3 so anything with more of it is good news.

It’s a great hormone supported and it actually helps the hypothalamus and pituitary glands, this good since they control how much T your testes produce.

S.A.N Free T contains a disappointing 400 IU. To give you an idea of just how low that is, the minimum amount required to be considered within the optimal dosage is over 3,000 IU. To rub salt into this wound, TestoFuel contains a huge 5,000 IU. That is reflective of a company that knows what they are doing. A huge leap forward there for TestoFuel.

Unique Supplement Ingredients

That’s where the similarities end then. Let’s look a little deeper into what they have to offer with their ingredient selection.

First up, let’s look at…


Oyster Extract

A brilliant inclusion due to its Zinc levels, now TestoFuel already has Zinc, but at a sensible 10 mg (the maximum daily consumption should be around 40 mg). Therefore the inclusion of Oyster Extract should serve as a little booster of zinc, as well as containing a lot of its own benefits.

Zinc is important for sexual health since low levels often mean increased levels of estrogen (not what you want).

Anyone looking for benefits for gym related purposes will appreciate the fact that it helps to enhance the effectiveness of your protein. It does this by allowing your body to use more of it through RNA transferase – significant for protein synthesis.

A clever inclusion there from TestoFuel.


A deficiency in this can lead to a decrease in T levels so it is important to maintain healthy levels. Another ingredient that many in the western world are deficient in, taking a supplement is advisable. There have been studies that have found it to increase levels of T by around 24% when taken alongside intense exercise.

S.A.N Free T

Calcium D-Glucarate

This is where this product starts to unravel a little. Yes the vitamin D3 dosage was way too low, but at least it is shown to be a proven T booster.

However, this is an ingredient we don’t often see in testosterone boosters. This is because there is very little evidence to suggest it is beneficial for your T levels. There is even a chance that it may have a negative effect on testosterone.


What we can say is that this is often found in many vegetables including cauliflower, cabbage amongst others. Unfortunately this alone is not to convince us it should be included in a T booster.

Sure, it is safe but we can’t find any information online to support its use as a testosterone booster.

S.A.N Free T vs TestoFuel Side Effects

We are pleased to be able to say that neither of these products contains anything of concern. If you have any allergies to Oysters, then that might put you off TestoFuel.

Otherwise they are completely safe to use.

It started relatively close but it is going to take a lot to beat a product like TestoFuel.

In fact, we believe that nothing we have seen gets close enough so far. The combination of effective ingredients and dosages make it a tough testosterone booster to beat.

On top of this the ingredients are natural and there are no proprietary blends. For us it ticks all of the important boxes for a testosterone booster.

This is why we rate it so highly.

S.A.N Free T contained some effective T boosters, but they were let down by some of the dosages and ineffective ingredients. We can see why it is a popular choice, but TestoFuel ran away with this one.
