TestoFuel vs Prime T

Looking for a T booster that ticks all the regular boxes in terms of its promises? Our TestoFuel vs Prime T review can help.

With so many products available on the market, you don’t need to accept an inferior product. No longer do you need to just grab whatever your buddy is using, or go for the best packaging. This isn’t a racehorse you’re taking a whim on – so choose carefully.

These two products are two of the best on the market that we have seen. But only one of them can win today.

We at CleanLeanMachine are passionate about supplements, and as a result, there are only a handful of products we fully recommend. Let’s read on to see if either of these two supplements makes the cut.

Both of these T-Boosters claim to:

  • Promote Testosterone
  • Increase Libido
  • Elevate Your Mood
  • Enhance Your Strength and Muscle Mass

That’s all very well, but which one delivers on its promises more? We will consider a few factors here, the ingredients being arguably the most important and dosages of course. But one will also be safer than the other.

Time to get into the companies.

TestoFuel vs Prime T: Who Makes These Products?

Roar Ambition

Roar Ambition are the people behind TestoFuel and having reviewed some of their other products, we can tell you we like what we see.

Not only do they create some of the best products on the market, including Instant Knockout, one of the most effective fat burners around, but they also review their ingredients and dosages list every 3 months. This is an incredible commitment to quality and something we don’t see very often.

This means you are constantly getting the most modern and safe product possible at that time.

Although celebrity endorsements don’t necessarily mean a better product, sometimes you have to pay attention. Robby Robinson, former Mr. Universe puts his name to TestoFuel, take a look at the guy and is physique – he’s in his 70’s!

RSP Nutrition

Prime T is made by RSP Nutrition, another company with a good reputation. Their website doesn’t give a lot away to be honest, but we can’t see anything online about them that would make us worry.

The website have a pretty generic about us page that is filled with their mission statement but not a lot of actual info.

They also have a good set of endorsements, theirs are of arguably the less famous but quite accessible with highly regarded CrossFit trainers and professional athletes amongst their ambassadors.

TestoFuel vs Prime T Ingredients

This is where we found out just how good each one is. With an initial look, it is good to see that neither use proprietary blends. So ingredients, as well as dosages, are fully disclosed.

Before we put anything into our system, we always check what it is that is going in. We’re not human guinea pigs so we look out for any warning signs and pass the knowledge onto you.

With a lot of the top-rated ingredients for testosterone boosters on both labels, this promises to be a good competition.

Mutual Ingredients

This is where the dosages matter…

If both include an ingredient, it will come down to who has the best optimal amount in their servings.

Vitamin D3

An almost essential ingredient in any T-booster, it appears to be the backbone of a good supplement.

This is good news since the western lifestyle and diet means many are deficient in Vitamin D3. Created by your body when your skin is exposed to sunlight, maybe it is because our working habits mean we are indoors too much!

TestoFuel has a generous 5,000 mg and Prime T contains 3,000 mg, which is just shy of the minimum optimal dosage so we will give this one to TestoFuel.

D-Aspartic Acid

Another great ingredient, so for both to include this, they should be commended. Two quality supplements here going by early impressions. DAA is great for your T levels as it tells your brain to release hormones that are beneficial for the production of testosterone.

TestoFuel contains 2,300 mg and Prime T has 3,200 mg. These are both within the optimal range for effectiveness, but we will give it to Prime T since theirs is a generous amount.


Another great ingredient for T boosters, this is often thought to be good at suppressing estrogen as well as supporting a healthy prostate.

You will find that most of the better T boosters contain this product and with many of us deficient it is an important ingredient.

There isn’t a lot to split them here since TestoFuel contains 10 mg and Prime T 12 mg so we will call it a close draw.


Some people point out a study conducted on animals that show this to be a good T booster, yet many sources point out the effectiveness for humans is inconclusive and points more towards ineffectiveness.

We like it as a libido enhancer and what it can do for stabilizing insulin levels – which is good news for testosterone.

It’s not the best ingredient here so the fact that there is more in Prime T seems like a bit of a waste to us.

Unique Ingredients

With not a lot to separate them so far, this should bring us closer to our winner, are any of the remaining ingredients unsafe and which has the better remaining ingredients?



Excellent for helping your muscles to relax, so after your workout, this will feel like a relief. It also helps to ensure your nerves are not overworked throughout the workout, great since these send vital messages throughout your body, and this aids your recovery.

Vitamin B6

A smart choice for any T booster this benefits your body by stimulating androgen receptors which helps testosterone production through your testes. It has also been shown to regulate the levels of estrogen in your body so its inclusion in testosterone boosters is a clever choice.

A deficiency can result in anemia as well as skin complaints.

Oyster Extract

If Prime T had slightly more Zinc in it earlier, then this more than makes up for it, since Oyster Extract is so high in Zinc.

It is also great at enhancing the effectiveness of any protein in your body by supporting the protein synthesis process. It also happens to be a great all-rounder for your body with many vital vitamins and essential elements.

Prime T


You come across this quite a lot in the supplements world and it is a good ingredient to include. It is derived from black pepper and is often included as it helps to enhance the effectiveness of other ingredients.


When we saw this ingredient we were disappointed. There have been some studies that have shown this to be a useful T booster since it stops your T from turning into estrogen.

There are, however, more studies that show that this isn’t the case. In fact, the opposite is more likely. Any dosage over 100 mg runs the risk of having an anti testosterone effect, and Prime T has 250 mg.

This for us, is a bit of a risk, and it’s not that we’re completely risk averse, but we do like our supplements to be.

TestoFuel vs Prime T Pros and Cons

TestoFuel Pros

  • Natural Ingredients
  • Safe to Use in Competition
  • Many Great Reviews

TestoFuel vs Prime T Side Effects

This section could have been really simple if it wasn’t for Prime T’s inclusion of DIM. TestoFuel is proven to have no side effects and it’s all natural ingredients and optimal dosages support this. Unless you are allergic to Oysters.

Prime T, however, contains DIM, and the side effect of more estrogen includes the increased risk of man boobs, unfortunately that isn’t something we like to see from a T booster.

A real tight battle that went all the way to the wire.

Unfortunately, Prime T let itself down a little in the end. The inclusion of DIM meant that it was a no contest. It had some good points but it was also missing some pretty effective T boosters.

TestoFuel has proven ingredients, is completely safe with no side effects and has some incredible testimonials on their site. In fact, we have commented various times on its effectiveness and still haven’t found anything to beat it.
