Performance Lab Sport T-Booster vs RSP Prime T

A true battle of the beasts today. Our Performance Lab Sport T-Booster vs RSP Prime T review pits two very different supplements against one another.

We have one that really goes down the clean and safe route in Performance Lab Sport T-Booster. On the other hand, RSP Prime T is a serious contender that is well respected by many.

These brands couldn’t be further apart in some ways which should make for a very interesting comparison.

What is it that we’re looking for though? The below would be a good start for any testosterone booster:

  • More Strength
  • Enhanced T levels
  • Increased Libido
  • Less Estrogen

If they are going to impress then they are going to have to do all this in the safest and most efficient way possible. Time to see what they have to offer, starting with the companies behind the products.

Performance Lab Sport T-Booster vs RSP Prime T: Who Makes These T-Boosters?

Opti NutraPerformance-Lab-Sport- T-Booster

Here we have the UK based company behind Performance Lab Sport T-Booster.

We mentioned earlier that they like to make clean products, but what does this mean? Let’s start by saying that not enough companies adopt this approach. They go to great lengths to create natural products with enhanced ingredients.

They use their patented technology BioGenesis to increase the potency and overall quality of every ingredient.

This means each ingredient is eco-friendly as well as free of allergens, GMO, additives, soy, synthetic additives and banned substances. They are as clean as you could hope for then.

They are popular with many people because they are vegan-friendly. This is because they use Plantcaps capsules. Not only does this mean the product is absorbed a lot faster, but it also means they are bettering a lot of the vegan-friendly competition.

This is because other companies often use Cellulose. This isn’t natural or as effective and is made from semi-synthetic polymer.

Opti Nutra also has a money back guarantee and a wide range of products.

RSP Nutritionprime t testosterone booster supplement

A big name brand like this often comes with some endorsements.

This generally covers Crossfit coaches, athletes, and professional pole vaulters, some of these have featured on the cover of Men’s Health Magazine.

Their about page is a little generic and this Florida based company do have a slick edge to their branding. There is all the usual information such as returns policies and Ts&Cs.

They have an extensive range of products and sell everything from pre-workouts to proteins. RSP Nutrition even has merchandise with everything from T-Shirts and Caps to blender bottles.

There are some useful articles for nutrition but we couldn’t find anything about a money back guarantee.

You can find their products on Amazon but that’s not a strategy that everyone favors. Performance Lab, for example, chooses not to sell on Amazon. They believe that by doing so they would be listing their products alongside a lot of low-quality supplements.

This is true for a lot of products so we can see why.

Performance Lab Sport T-Booster vs RSP Prime T Ingredients

This is where we can really set these two apart.

The good news from the off is that neither uses proprietary blends. This means all the dosages are revealed and we can really see how effective this can be.

Mutual Ingredients

D-Aspartic Acid

The only mutual ingredient but a great start.

We like it because it has so many uses. What really sets it apart though is the fact that it is fast acting. One particular study shows how it can increase T levels by 50% in under 2 weeks!

It stimulates the luteinizing hormone to raise T. This, in turn, communicates with the testes to create and release more testosterone.

It has even been shown to increase the Human Growth Hormone levels. DAA could also keep the user youthful and help to heal injuries.

It also has benefits for sexual health such as its ability to increase sperm count. This makes it a good all-rounder.

DAA works well when taken alongside Luteolin.

This is because although it raises T levels, our bodies can still convert a lot of this into estrogen. Luteolin helps to prevent this making them a clever pairing.

The good news is that Performance Lab Sport T-Booster have included both of these ingredients.

The 1,000 mg in Performance Lab Sport T-Booster is more potent than it sounds due to their use of BioGenesis. It is more on par with the 3,200 mg in RSP Prime T that it seems.

Individual Ingredients

Performance Lab Sport T-Booster

Mucuna Pruriens

Another proven T booster.

It works because it helps the body to cope with the effects of stress. Being anti-cortisol it supports healthy T levels by protecting them. Stress is bad news for T.

Mucuna Pruriens helps the testosterone in the body to stay where you want it for longer. This helps with muscle development.

When taken alongside Ashwagandha it works even better. This is because they work in a similar way. Performance Lab has included both ingredients to compliment one another.

Still, the biggest benefit here is that it suppresses both estrogen and prolactin. discusses how it works against prolactins suppressive effect on libido and testosterone.

As higher prolactin levels are often linked to lower testosterone, this is a good thing.

The dosage of 150 mg is optimal yet again.

Ashwagandha Extract

An ingredient that benefits overall physical performance as well as your T.

For testosterone, it is another ingredient that stimulates the luteinizing hormone. Create more T – tick! tells us that it works as an androgen, helping the body to cope with stress.

So, an ingredient that increases T levels and protects them, this is exactly what you want your T booster to do.

It contains antioxidants that protect the body from free radicals.

An all-around great ingredient that also enhances libido, it does just about everything you want a T-Booster to do in one ingredient.

The quality of Ashwagandha is as good as it gets. KSM-66 is the most potent available. 300 mg is another great dosage made even more potent by BioGenesis.


The last ingredient in this supplement and another good one. This proves they have gone for quality over quantity.

It is believed to be an aromatase inhibitor. This stops the body from turning our precious T into estrogen.

As well as this, studies have shown that it protects the body from free radicals as shown by a study from the National University of Singapore. Because of this, our T levels are protected.

The 30 mg is another very good amount.

RSP Prime T

Vitamin D3

Up there with the best T boosting ingredients it is one we like to see.

The fact is, low levels of D3 are linked to low testosterone. Since many of us are deficient, keeping it topped up is always a good thing.

Our bodies actually create their own D3 when our skin is exposed to direct sunlight. Clearly, we aren’t getting our fix of the sun that our bodies need! A proven ingredient with the backing of many studies but what about the dosage?

The general consensus is that you need at least 3,300 IU for an optimal dosage. The 3,000 IU in RSP Prime T falls just short.


Another good ingredient.

This traditional medicine has been used for centuries as an aphrodisiac.

It also keeps insulin levels balanced. This is good since when our blood sugar levels fluctuate it can have a negative effect on our T.

WebMD confirms that it appears to slow absorption of sugar in the stomach and stimulate insulin. Both of these effects lower blood sugar in people with Diabetes.

A favorite ingredient in various T boosters The 500 mg is a good dosage as well.

Folate Acid

Known as a pregnancy supplement more than anything else.

It is water soluble and supports general health but we aren’t quite sure why it is included here. It might be a natural way of increasing T levels but the dosage is very important.

WebMD advise that is is likely to be safe when taken under 1,000 mcg. The 800 mcg fits into this but it isn’t the most reliable T boosting ingredient on the market.

Vitamin B3

Thought to mainly have benefits for energy levels. It helps the body to break down proteins but does not appear to have any direct benefits to testosterone.

It might be good for insulin levels but they already have a proven ingredient for that in Fenugreek.

It will only be of benefit in doses of around 1 g (see and since this product only includes 20 mg it is highly unlikely to have the desired effect.

Vitamin B12

A decent ingredient for overall sexual health.

It doesn’t raise T levels which is what we are after but it can aid testicular health. It will help with sperm production. This is important for the over 30’s where T levels decrease year on year for the rest of our lives.

The 12 mcg isn’t taking up too much room.


Up there with the better T boosting ingredients it is back to the proven nutrients thankfully.

Zinc is another that stimulates luteinizing hormone, increasing T levels. It also protects them. By stopping the amount of T our bodies use up during intense workouts, saving more for later.

Such an important ingredient gets the dosage it deserves in the 12 mg included. This is just about enough to get the desired effect.


Another ingredient that is good for sexual health. It might help increase sperm quality and even help with sex drive.

There is no evidence though to suggest that it can raise testosterone levels. This is what we are in need of. Many of the ingredients have links to T but do not affect it directly.


Often found in leafy veg and in particular Broccoli.

The studies suggest it isn’t the most reliable ingredient and although there are sources that say it can keep estrogen suppressed, there are others that show it can increase estrogen.

Obviously, this is the opposite of what we are after and makes this a bit of a controversial ingredient.

The support for its ability to lower estrogen in men is limited. In fact, most of the studies show it to decrease estrogen in women.

Some believe that this is because it regulates bad estrogen levels and that good estrogen can actually help the user to maintain good T levels. Further studies are needed to support this though.

For many, this will be an ingredient to avoid especially since there are many reliable estrogen suppressants.

Safed Musli Extract

This is a tropical herb that could benefit overall sexual function.

The fact that further studies are required to support its benefits for T says it all. Another ingredient that helps with sexual health only, that’s not what we are here for.


A decent ingredient and one that inhibits the Sex Hormone Binding Globulin.

A lot of T boosters contain ingredients that do this for a reason. Since SHBG binds your T and makes it unavailable for use, anything that can reverse it is of benefit here.


A good conclusion even though it doesn’t directly boost T.

This is because it enhances the benefits of the other ingredients. Since there are some good testosterone boosting ingredients this is a good selection.

Performance Lab Sport T-Booster vs RSP Prime T Side Effects

The good news is that neither product should cause the user any side effects.

Of course, RSP Prime T have included DIM. This could have a negative effect in that it might increase estrogen but this isn’t unsafe.

Performance Lab Sport T-Booster have gone through the effort of making their product as clean and safe as possible. When you look at the list of additional ingredients RSP Prime T has PEG-400, Microcrystalline Cellulose, HPMC and Silicon Dioxide to name a few it is clear it is not as clean.

As always, we recommend that you check the label if you have allergies.

A close contest but when you consider this is the product that had no unwanted additives and only proven T boosters, it was an easy decision.
