Did you know that there are actually 5 different Bulk mass gainers on the market? That’s a lot to choose from. I don’t know any other supplement company that has this many weight gainers.

You see, Bulk are ahead of the game in many ways. Sure, their packaging might not be flashy and full of false promises, but they know how to do the basics really well.

They have mass gainers for different goals, and today, I’m going to test out their lean gainer, a seemingly great option if you’re looking to gain size while keeping fat accumulation to a minimum.

So in this Bulk Lean Mass Gainer review, I’ll be sharing my report on the taste, mixability, and ingredients, to see if it’s worth a place in your supplement stack.

Bulk Lean Mass Gainer Ingredients

Slow-Digesting Scottish Oats

The Bulk Lean Mass Gainer ingredients

You'll find slow-digesting Scottish oats in this mass gainer, providing a healthy source of complex carbohydrates that release energy evenly throughout your workout. Crashes be gone!

With an equal amount of carbs and protein per serving, this shake is made for lean gaining. So while it might not suit hardgainers, it’s perfect for those who gain fat more easily and who want to maintain a leaner physique while bulking.

3-Protein Blend

The 3-protein blend in the Bulk Lean Mass Gainer formula—whey protein concentrate, milk protein concentrate, and egg white powder—offers a solid 34 grams of protein per serving. 

This combination of fast and slow-release proteins ensures that your muscles receive a continuous supply of amino acids, which is crucial for optimising hypertrophy.

Glutamine Peptides

Glutamine peptides, with a specific amount of 3.8 grams per serving, are included in Bulk Powders Complete Lean Mass Gainer to promote muscle recovery and help minimise muscle breakdown after intense workouts. 

By enhancing recovery, glutamine peptides make your muscles feel less sore, enabling you to get back in the gym sooner so you can spike protein synthesis once again and trigger even more gains.

5 Grams Of Fat

Bulk Lean Mass Gainer contains just 5 grams of fat per serving, giving you a healthy and balanced macronutrient profile. Most of these fats are probably from the oats, so, in that sense, they’re completely naturally occurring nutrients.

How Does Bulk Lean Mass Gainer Taste?

The Bulk Lean Mass Gainer scoop

Based on customer feedback in their Bulk Lean Mass Gainer reviews it seems that people genuinely like the taste of this mass gainer, which is always a bonus when you'll be consuming it regularly.

And based on my own taste testing, I’m happy to report that this little-known weight gainer surpassed my expectations! It wasn’t overpoweringly sweet, but it definitely tasted more like a milkshake than a gritty sports supplement, that’s for sure.

Because this gainer uses oats rather than maltodextrin, it has a more natural taste. This is great if, like me, you hate the taste of anything artificial.

In terms of flavour options, we have the usual 3 suspects; strawberry, chocolate, and vanilla. Bulk won’t win any awards for flavour innovation, but they sure know how to create a shake that goes down a treat.

Does Bulk Lean Mass Gainer Mix Easily?

You might be wondering if Bulk Lean Mass Gainer mixes easily without any clumps. Well, you're in luck, as most users report that it blends smoothly, making it a breeze to incorporate into your daily routine.

That’s my experience too. Thanks to the ultra-fine Scottish oats, the powder mixes easily in a shaker bottle with either milk or water. Unlike other shakes, Bulk Lean Mass Gainer doesn’t stick to the bottle or clump, making it much more enjoyable to drink.

Mixing up your shake is so easy as well. Start by pouring around 350ml of your desired liquid into the shaker, then add the recommended mass gainer amount on top. Give it a good shake until no clumps remain, and you'll achieve the perfect consistency.

Value For Money

Side view of Bulk Powders Lean Mass Gainer

Bulk Powders Lean mass Gainer isn’t the absolute cheapest option out there, but it’s also not that expensive, either.

Since there’s a 1:1 carb-to-protein ratio, you’re getting a lot of protein for your money. Or, to put it another way, you’re not just paying for endless grams of carbs and only a slither of protein.

What I like about Bulk is that they offer their gainers in a variety of sizes. So, if you just want to give Bulk Lean mass gainer a try, you can pick up a 1kg packet for cheap.

However, if you want to get the best savings, you can pay more for a big 5kg bag, which works out considerably cheaper on a per-kilogram basis.

Who Should Take Bulk Lean Mass Gainer?

If you're looking to achieve lean gains and develop muscle mass while minimising fat gains, then this is the supplement for you. 

Mass gainers are designed to help people who struggle to gain weight, especially for those who find it hard to consume enough calories through their regular diet. But unfortunately, many are filled with low-quality protein and junk carbs. But not this lean gainer.

Firstly, let me say that real hardgainers may want a more calorie-dense formula with a higher carb-to-protein ratio, which is more suited to aggressive bulking and rapid weight gain.

But anyone who wants—to the best of their ability—to stay lean while gaining size should definitely consider adding Bulk Lean Mass gainer to their supplement stack.

Additionally, busy individuals who find it challenging to prepare and consume enough meals throughout the day can also benefit from this weight gainer. Let's face it, life can get hectic, and it's not always easy to fit in multiple meals when you're juggling work, family, and other commitments. 

Who Shouldn't Take Bulk Lean Mass Gainer?

If you're someone whose primary goal is shedding fat and getting lean, then taking even a lean mass gainer won't be quite ideal for you. These supplements are packed with calories and are specifically designed to help individuals put on muscle mass, which may not align with your fitness objectives if you're focusing on fat loss.

Also, if you’re a mega-hardgainer and need a huge calorie intake to trigger weight gain, then you might want to look for a more calorie-dense shake that has more carbohydrates than protein.

Lastly, remember that mass gainers alone won't magically give you the muscle gains you're seeking. If you already consume a calorie-dense diet and are consistently hitting your macronutrient targets, supplementing with a mass gainer might lead to an excessive calorie surplus, ultimately causing unwanted weight gain instead of lean muscle mass development. 

What's The Verdict?

The back view of Bulk Lean Mass Gainer

You might be wondering what sets this Bulk Lean Mass Gainer apart from its competitors. Well, here's the lowdown on why this particular supplement could be your new go-to for muscle building and weight gain.

First up, it's worth noting that this mass gainer doesn't skimp on quality. Unlike some other products on the market, this one is formulated with premium ingredients. The protein is sourced from quality whey, milk, and egg protein, giving you a sustained release of amino acids that will keep muscle protein synthesis firmly switched on.

Additionally, this mass gainer doesn't rely on heaps of sugar to pack in the calories. Instead, it boasts complex carbs from ultra-fine oats (hence the great mixability), giving you steady energy when you need it without rapid insulin spikes. This ensures you can gain lean mass rather than piling on unwanted fat.

Add in the glutamine peptides, and you can see why this simple yet effective gainer is one of my top choices for lean gaining and muscle recovery.

So there you have it. I hope you found my Bulk Lean mass gainer review informative. While there are many good gainers on the market these days, I really think that this formula is one of the purest and most reliable if you’re looking to put on quality size without the fat.
