BPI Bam! Review - LeanBulking

About The Product

BAM! is a pre-workout supplement by BPI Sports Nutrition. It comes in 25 serving containers, priced at $44.99 on GNC.

You have the choice of 2 flavors – Rainbow Ice & Fierce Blue Lemon. Sounds tasty, but the most important feature of a pre-workout is its ingredients (we’ll expand on this in the section below).

Who Are BPI Sports?

BPI Sports are a supplements company that market a range of supplements, from whey protein to pre-workouts. But there wasn’t much information available on their website.

They sponsor some high level athletes, including Logan Franklin and Jay Cutler – so let’s see whether BAM! can live up to their reputation.

About The Ingredients

First of all, you need to know that BAM! contains a proprietary blend. Basically, this increases your risk of side effects – we’ll explain why these blends are bad, and what they are below.

What are proprietary blends? 

Simply put, proprietary blends are mixtures of numerous ingredients that are shown to you under one quantity. The blend in BAM! is named ‘Lipomal Matrix Delivery System‘ which you can see from the ingredients list below.

You’ll find that the overall quantity is 500mg, but you’re not given the exact amount of the two ingredients inside (phosphataidylcholine & Phytosterol). This can cause problems if you’re sensitive to any ingredient inside these blends – increasing your risk of suffering from side effects.

BAM! contains banned ingredients

Basically, Yohimbe is banned in the UK and other countries for causing harmful side effects (see side effects section for more info). We’ve analyzed each ingredient for you in this section – so you can see how effective BAM! really is.

Here’s Everything You Need To Know:

Vitamin D3 

We hate to talk negatively about Vitamin D3 – it’s one of the best testosterone boosting ingredients available, and our favorite T-Booster contains it.

But it’s not needed in a pre-workout supplement. You need to consume Vitamin D3 in 3-4 servings spread throughout your day for it to work (as you’ll only consume BAM! once per day, it might not do much).

Vitamin D3 won’t cause any side effects or anything negative, but BPI Sports could’ve added something more suited to immediately improving your gym session here – such as Rhodiola Rosea, which has shown to reduce fatigue and improve your mind-muscle-connection in the gym.


L-Carnitine’s proven to reduce fatigue and boost endurance – 2 great benefits to improve your workout. For this reason, it’s one of our favorite pre-workout ingredients.


This can improve your focus, but BAM! contains Caffeine (which improves your focus, along with your strength, endurance, and energy levels too).

As L-Tyrosine has no other benefits apart from boosting cognition, it’s not really needed here.


This is a great ingredient in a pre-workout, as long as it’s not over-dosed (we prefer Caffeine dosages under 200mg in pre-workouts). BPI Sports has added 250mg, so it’s been slightlu over-dosed in BAM!

If you’re not really sensitive to Caffeine, you should be safe from side effects like jitters and energy crashes. However, if you’re sensitive to Caffeine, we recommend looking for a pre-workout containing a Caffeine dosage between 150mg-200mg.



Choline is one of the worst ingredients you can find in any supplement. Basically, it’s not shown to provide any benefits to improve your workout – but causes fishy odors in your breath and sweat.

Although this isn’t a harmful side effect, smelling like fish in the gym isn’t enjoyable – which is why we avoid this ingredient, especially as it’s useless.

Yohimbe Bark Extract 

Yohimbe is more commonly seen in fat burner supplements, as it’s shown to promote fat loss – it’s also shown to be effective in treating erectile dysfunction (but if you’re looking for this benefits, then a testosterone booster is what you want).

Not only that, as fat loss is it’s main benefit, it’s not really needed in a pre-workout supplement – Usain Bolt wouldn’t get in the pool with Michael Phelps, so why should this pre-workout try and compete with fat burner supplements?

Anyway, here’s the big problem: Yohimbe is banned in the UK and other countries for causing harmful side effects. Check out our side effects section for more info.

The Proprietary Blend

This blend contains both Phosphatidylcholine & Phytosterol. But no-one knows the exact dosage of either ingredient in this blend.

All we know is that the overall quantity of this blend is 500mg. What do these ingredients do?

Well, they’re believed to be cognitive boosting ingredients, meaning they’re supposed to increase your focus. However, no studies have proven whether they work yet.

Not only that, Phosphatidylcholine can cause side effects from orally supplemented (check out our side effects section for more info).

Did You Know… Citrulline Malate is the best ingredient to improve your muscle pumps? It works best in dosages of 6,000mg.

BAM! Review Conclusion

This isn’t the best pre-workout we’ve seen, but it’s not the best either – we believe 3 stars is a very fair rating of BAM!.

Things We Like: 

  • L-Citrulline is a great ingredient for promoting muscle pumps.
  • L-Carnitine can reduce fatigue and boost endurance.
  • Caffeine has shown to improve endurance, strength, and focus.

Bad Things About BAM!: 

  • Vitamin D3 is a great testosterone boosting ingredient, but won’t have immediate effects to boost your workout. It’s better in a T-Booster.
  • Choline proven to offer no benefits, but causes fishy odors in your breath and sweat.
  • Yohimbe is banned in the UK and other countries for causing harmful side effects.
  • The proprietary blend increases your risk of suffering from side effects.

Bottom Line: BAM! isn’t worth its asking price ($66.99). You can find much better pre-workouts for the less cash – but as we’ve said, it’s definitely not the worst product we’ve reviewed.
