Review Overview – What does Mdrive Pro do?

Manufactured by Mdrive, 4×4 is an all natural testosterone booster on the market that has been seen to promote:

  • Testosterone
  • Nitric Oxide
  • Strength and Size
  • Male Sexual Function


But how well does it really work?

In this review, we look closer at 4×4 to see how effective it really is.

This is what you need to know:

How are the servings?


With one serving per day, there’s only so much progress you can expect to make with this T-Booster.

Your body can only absorb so much at a time – with only 1 serving a day, your body is going to take what it can and fail on the rest.

For the best results, you need it split up. With a 24 hour gap between servings, your t-levels may drop back down to their baseline levels.

For the best results you need 3 – 4 servings per day, this ensures you’re getting a constant supply of the nutrients you need and make reliable progress.

Mdrive needs to sort this out.

What about the ingredients in Mdrive 4×4?

Not great.

Although there are one or two good ingredients, they’re overshadowed by the proprietary blends.

Why is this bad?

Because proprietary blends stop us from knowing how much of each ingredient we’re getting.

It hides the values of each nutrient used – this stops us knowing how effective it is overall and damages the product’s credibility.

Don’t worry, all the ingredients have been summarized at the end.

Ovine Placenta

Not a great start.

Although an interesting choice. Studies have shown that this ingredient isn’t actually that effective.

The main appeal of this nutrient is where it’s came from – rather than what it does.

It’s not a good choice.


A better choice.

An indirect testosterone booster, Ashwagandha works by lowering the stress hormone cortisol.

Stress has been seen to directly interfere with and lower testosterone. So less of it you have, the better.

Tongkat Ali

Not so great.

Once though to boost testosterone, studies have shown that this may not be the case.

Also known as LongJack, there are no reliable studies that link this nutrient to testosterone boosting.

At most, it may have a mild effect on libido.


One of the better t-boosting nutrients.

Boron has been seen to promote testosterone while simultaneously lowering estrogen.

It’s a good choice.

Agmatine Sulphate

A metabolite of L-Arginine.

Although L-Arginine has been seen to promote nitric oxide, which increases blood flow – it doesn’t actually perform that well when supplemented orally.

Studies have shown that the nutrient isn’t properly absorbed after oral supplementation.

For the best results you need to stick to something like L-Citrulline, which is converted into L-Arginine after being absorbed, bypassing the problem.


An amino acid, and not a very good one.

Studies have shown that this amino acid has no unique benefits associated with it.


A branded nutrient that is thought to boost erections.

However there are no available studies that vouch for ViNitrox’s effects.

It may not have the best effects.


A better choice for blood flow – although clearly under dosed.

L-Citrulline has been seen to promote blood flow by its ability to be covered to L-Arginine.

However, you need a lot of it to work. Studies have shown you’re 6 – 8g of L-Citrulline at least to get the desired results.

Saw Palmetto

Aimed more at male health than testosterone.

Saw Palmetto has been seen to mildly reduce the effects of an enlarged prostate, and promote overall prostate health.

It does not boost testosterone.

Stinging Nettle

A good choice for free testosterone.

Stinging Nettle has been seen to inhibit Sex Hormone Binding Globulin – a protein that binds to testosterone and strips it of its anabolic potency.

With less active SHBG, Stinging Nettle helps to raise available testosterone.mdrive-4x4-results

Ingredients Bottom Line:

Overall, Mdrive 4×4 doesn’t have the best testosterone boosting profile we’ve seen.

There’s quite a few ineffective ingredients in there, but one of the bigger setbacks are those proprietary blends.

You don’t know how much of each ingredient you’re getting – and by our guess, many are under-dosed.

It’s not the best option out there.

Side Effects

There have been no side effects reported with the use of this T-Booster.

Is there anything better than this Testosterone Booster?

There absolutely is.

We’ve done the research, and looked far and wide for the best supplements on the market that promote:

  1. Muscle Gains
  2. Fat Loss
  3. Testosterone Levels
  4. Energy
  5. Mood
  6. Sex Drive

And it we’ve finally narrowed it down to just three.

These are the best testosterone boosters on the market, that both myself and our readers agree provide the best results. You can check them out below:

Mdrive 4×4 Review Conclusion

All in all, this isn’t the best testosterone booster on the market and there are several reasons why.

From this review, this is what you need to know about Mdrive 4×4:

  • Poor Servings – With only 1 serving a day, the testosterone boosting process will be slow. You need regular top-ups for fast development.
  • Proprietary Blends – You don’t know how much of each ingredient you’re getting, or how effective it will be overall.
  • Ineffective ingredients – Many of the nutrients used lack clinical backing.

On the whole, it isn’t the best one out there.
