Iron Brothers Testosterone Booster Review – Should You Buy it?

Here’s our Iron Brothers Testosterone Booster review. Will this Testosterone Booster improve your libido, sex drive, energy levels, as well as provide other benefits of having higher T levels? We find out below – starting with a short summary.


  • Designed to sustainably and naturally elevate your testosterone levels and improve libido
  • Features several great libido-boosting ingredients
  • Contains Ashwagandha, Boron, and a few other proven T-boosters, however, many of them are underdosed
  • Zinc, on the other hand, is dosed too high at 40mg per day, risking zinc toxicity in the long-run
  • Missing a few core ingredients
  • No proprietary blends (big thumbs up for this)
  • While we’ve found it to be decent for increasing libido, it’s ineffective at actually raising testosterone
  • 90 capsules, 3 caps per day
  • Relatively affordable at 29.97 per bottle

What is Iron Brothers Testosterone Booster?

Iron Brothers Testosterone Booster is a natural supplement designed to increase your levels of testosterone – naturally.

Unlike steroids, it doesn’t cause a dependancy or mess with your hormones directly. Instead, Iron Brothers Testosterone Booster uses Ashwagandha, Zinc, LongJack and other ingredients to nudge your body to make more of its own T.

Apart from improving muscle growth and lean body mass, Iron Brothers Testosterone Booster is also promised to deliver you more energy and better mood throughout the day.

However, it’s missing some of our favorite ingredients for testosterone, and some of its ingredients are underdosed. This begs the question, how effective will Iron Brothers Testosterone Booster be for you?

Iron Brothers Testosterone Booster: Dosage Directions

Iron Brothers Testosterone Booster dosage is 3 capsules per day. Their website doesn’t say specifically whether to take it all at once or spread evenly throughout the day. It also doesn’t state exactly whether to take it with or without food.

Ingredients in Iron Brothers Testosterone Booster

Iron Brothers Testosterone Booster Ingredients

Iron Brothers Testosterone Booster contains the following ingredients:

  • Vitamin D (25mcg)
  • Niacin (40mg)
  • Zinc Chelate (40mg)
  • Tribulus Extract (500mg)
  • Epimedium Extract (400mg)
  • Fenugreek Extract (300mg)
  • Maca Root Powder (250mg)
  • Ashwagandha Extract (150mg)
  • Diindolylmethane (DIM) (100mg)
  • Tongkat Ali (50mg)
  • Boron (5mg)
  • Bioperine Black Pepper Extract (5mg)

The ingredient doses are all shown on the label which is good. It enables us to check for safety and effectiveness of the supplement.

By contrast, when you see a testosterone booster with a proprietary blend that masks its ingredient doses, run away and don’t look back!

Okay so apart from transparency, what else is good about Iron Brothers Testosterone Booster? Well, not that much actually! It has a few excellent ingredients – zinc, vitamin D, Ashwagandha, and boron – but they are either underdosed or too highly dosed (more on this below).

The rest of the ingredient formula, while good for your libido, isn’t effective for actual testosterone booster.

Here’s a closer look:

Vitamin D

How important is vitamin D for our health? Extremely! Every cell in your body has a receptor for vitamin D. Among many functions it has, vitamin D also influences your testosterone production.

A deficiency in this nutrient is linked to low testosterone symptoms such as low libido and poor physical recovery. Studies show that around 3,332IU of vitamin D per day is ideal for reaping vitamin D’s benefits on testosterone. [1] Iron Brothers Testosterone Booster has only 1,000IU of vitamin per serving.


Niacin is a B vitamin that is supplemented for improving cardiovascular health and lowering cholesterol levels. Supplementing Niacin isn’t recommended if your goal is fat loss, as it’s been shown to elevate insulin resistance.

Zinc Chelate

Zinc is an excellent choice for a T booster. While zinc doesn’t necessarily boost your male hormone, it helps prevent dips due to stress, toxins and unhealthy lifestyle. The safe zinc dosage range is between 10-20mg per day. Any more than that and it can cause severe stomach cramps, nausea, and diarrhea. Excessive long-term zinc supplementation may lead to copper deficiency, as well.

Tribulus Extract

Tribulus is an herb famous for its benefits on prostate. It helps reduce inflammation in the organ, along with potentially improving your libido without affecting your testosterone levels. [2]

Epimedium Extract

Epimedium or better known as Horny Goat Weed, is an herb that does just what its name says. It will help improve your desire.

Fenugreek Extract

Fenugreek is one of the rare few ingredients in Iron Brothers Testosterone Booster that actually boosts testosterone. But how does it do it?

Well, Fenugreek is known for blocking the conversion of testosterone into DHT, which is another anabolic hormone that’s vital for men’s health. So while Fenugreek will help you maintain higher T levels, it does this at the cost of another important player, and may lead to hormonal imbalance as a result.

Maca Root Powder

Maca is a great libido booster. Although it doesn’t work in all men, some report an increase in both desire and performance. Interestingly, Maca does this without affecting your testosterone levels; so if you have sub-optimal T levels, Maca won’t help you get them back to an optimal range.

Ashwagandha Extract

Ashwagandha is an Ayurvedic herb known for its anti-stress effects. It lowers cortisol, a hormone that negatively affects testosterone and weight loss. As such, Ashwagandha indirectly promotes healthier testosterone levels.

Diindolylmethane (DIM)

DIM is a compound and a byproduct of another compound, Indole-3-Carbinol (I3C). I3C is found in broccoli and other cruciferous vegetables and is known to lower the female sex hormone estrogen. While DIM does appear to do the same in some men, it’s not as reliable, and may even lead to an increase in estrogen levels in some cases. This is why we think supplementing Indole-3-Carbinol instead of DIM is a better option if you want to maintain a more youthful testosterone-to-estrogen ratio.

Tongkat Ali

Tongkat Ali or LongJack is another effective libido booster in Iron Brothers Testosterone Booster. Although, it has no proven effects on testosterone.


Boron is a trace mineral that we get in small amounts from our diets, as its found in apples, raisins and nuts. Boron can boost your testosterone when supplemented in doses of 10mg per day or higher. Lower doses don’t produce the same benefit.

Bioperine Black Pepper Extract

Black Pepper Extract is a natural bioavailability enhancer. Compounds in black pepper allow your body to absorb other nutrients more easily – helping you with the digestion process.

Iron Brothers Testosterone Booster Reviews and Testimonials

At the time of writing, Iron Brothers Testosterone Booster has over 2,900 reviews on Amazon with an average score of 4.1/5 stars.

While Testosterone Booster seems to not have caused any side effects for most users, many reviews report lackluster results at best.

Here’s what some of them say:

“So far I think it is too early to tell a difference. I have taken 45 capsules only and so far I believe any motivation and/or energy boost has been placebo. But energy is energy! I hope to really see a big difference in my second bottle. My fingers are crossed for sure.” – Cameron L. (Amazon Customer)

“Husband has been taking this for a month and is noticing difference in the mirror, not helping as much in the sexual dept as seen in other reviews, looking to update this review after the second bottle.” – M.C. (Amazon Customer)

“Wish I would have done more advanced research online on the ingredients combination before purchasing this but live and you learn it’s not necessarily bad I haven’t noticed any noticeable results yet though.” – Richard Barber (Amazon Customer)

Side Effects

Iron Brothers Testosterone Booster may give you upset stomach and nausea if you take it on an empty stomach. This is because it uses 40mg of zinc per serving, which is the upper tolerance limit for the day. If you take any additional zinc from other suppements or from zinc-rich food, you risk long-term zinc toxicity.

Apart from zinc, the ingredients in Iron Brothers Testosterone Booster are safe and shouldn’t cause you any side effects. Of course, if you are not sure whether this supplement is right for your, or if you have any sort of a condition, please speak with your MD before taking this product!

Cost, Where to Buy, and Other Things to Consider

Iron Brothers Testosterone Booster is available on the official website as well as on Amazon. The price is $25.97 per bottle (30 servings).

Iron Brothers Testosterone Booster Review: The Bottom Line

Iron Brothers Testosterone Booster has several great libido-boosting ingredients. However, don’t mix this with testosterone boosting – the two terms are very different.

If Iron Brothers Testosterone Booster included more proven testosterone boosters, and if it properly dosed the testosterone boosting ingredients it does have, it would be more effective at raising your energy, confidence, mood, muscle building and fat loss and other benefits that higher T levels provide.

Iron Brothers Testosterone Booster also uses a high dose of zinc, so it may not be suitable if you already consume a significant amount of zinc through your diet or other supplements.

If you don’t mind the downsides though, and are just looking for a boost in your sex drive, then Iron Brothers Testosterone could a relatively cheap option to consider.
