About Grenade AT4

Grenade AT4 is a supplement that claims to work for hormonal support in men. 

These kinds of supplements are usually called Testosterone boosters and contain ingredients that support natural testosterone production in the body.

AT4 contains some of the best ingredients, but it’s also missing many.

The company behind AT4 is called Grenade and is UK based.

Grenade has a variety of different supplements for sale. This is a recognized brand in the industry.

AT4 testosterone booster is a product that has its ups and downs.

There are a few things I like about this formula and also things that I don’t like.

The thing I like is that it contains a few proven ingredients in optimal doses.

However, the downfall is the pricing point £59.99 or $76 for 20 fully dosed servings and the fact that it is missing many proven ingredients that the top testosterone boosters contain.

Testosterone boosters are used to increase muscle mass, strength, libido, and overall health in men. 

Testosterone is the hormone that makes us a man, and deficiency in certain minerals and vitamins could cause low testosterone, fat gain, low energy, loss in muscle mass, low libido, and low confidence.

Grenade AT4 Ingredients

Grenade AT4 contains five ingredients and no proprietary blend. Let’s check if these ingredients are good and if they are adequately dosed.

Vitamin D3

Vitamin D3 is included in most testosterone boosters for a good reason. Study shows that a deficiency in this vitamin can lower natural testosterone production. If you are insufficient in vitamin d3, supplementing with it could help your body produce more testosterone.

D-Aspartic Calcium Chelate

Usually, we see D-aspartic acid included in testosterone boosters, but this is only another version witch calcium and Zinc. Animal studies on D-Aspartic have shown that it can raise testosterone levels while human studies have shown inconsistent results. Many believe that D-Aspartic can increase natural testosterone, but we have to wait for another study to confirm this. 


 Studies have shown excellent results with Fenugreek, supplementing 600 mg of Fenugreek for 12 weeks, improved sexual function, and increased serum testosterone levels in middle-aged men. A full dose of AT4 is 720 mg, so it should be an effective ingredient to increase natural testosterone levels.

Passiflora Caerulea

There are no studies I could find that suggest that this ingredient will help to raise testosterone levels, strength, or muscle mass. However, some studies suggest it may help to calm the mind and sleep better at night.


The study reports that after only one week of boron supplementation at 6/mg, it increases free testosterone levels significantly. Boron also helps with the growth and maintenance of bone, boosts magnesium absorption, and improves cognitive performance.

Ingredients breakdown

 There are many beneficial ingredients included in Grenade AT4 that have shown to be useful when it comes down to raising or supporting natural testosterone levels. Most of them are well dosed and should work to give you the benefits.
The downfall of the supplement is that it’s still missing many vital ingredients that have shown remarkable results in increasing testosterone, strength, and muscle mass.
AT4 doesn’t have Ashwagandha, magnesium, vitamin b6, and ginseng, many of the other top brands have. 
Overall the ingredients are good, but they could be better.

Side effects

When looking at the supplement I don’t see any warning signs with the ingredients from my perspective. However, I would advise talking to a doctor about the use of any new supplement to make sure there is nothing that could cause dangerous side effects.

 Of course, pregnant or nursing women should never use a supplement like this and I strongly advise against it.
I looked at the ingredients and found possible side effects from using them, many of these side effects come with using too much of any given ingredient and there is no guarantee you will experience any of them. However, these side effects may be a possibility.

Potential side effects of using AT4 include 

  • Headache
  • Irritability
  • Nervousness
  • Feeling sick
  • Diarrhea
  • Indigestion
  • skin color changes
  • Seizures
  • Shaking
  • damage to blood vessels
  • Nausea
  • Vomiting
  • and more

As I said before I suggest talking to a medical professional before using any supplement and ask him if it is safe for you to use.


Grenade AT4 is a decent supplement to increase or support testosterone levels.
It contains many proven ingredients in good dosages.

This supplement is very expensive and it’s also not perfect by any means.

I have seen better and cheaper supplements than AT4 is and that’s why I think it cannot compete with the absolute best testosterone boosters.
I think those who will use it will feel an effect but I believe there are better options available especially because of the price. 
If this supplement would be a lot cheaper than the top testosterone boosters I would recommend it, but you are paying more and getting less which makes me advise against buying it.
That’s it for this Grenade AT review down below I have answered some frequently asked questions about AT4.
