Efectiv Mass, so we are told, is just what you need to support your weight-gaining ambitions. This scientifically formulated, calorie-packed UK shake has been specifically designed for those looking to bulk up and add quality mass to their frame.

Efectiv Mass boasts an impressive 45g of protein per serving, derived from a blend of whey and milk concentrate, as well as egg white powder. In addition, it provides a hearty 156g of carbohydrates sourced from oats, maltodextrin, and sweet potato. 

For me, the standout feature of Efectiv Mass is that you’re getting premium ingredients without the premium price tag. You can pick up a big 5kg tub for about the price of a month’s health club membership.

Efectiv Mass Formula and Ingredients

Let’s kick off this Efectiv Mass review by going over the effectiveness of the key ingredients in this UK-formulated shake.

Over 900 Calories

The Efectiv Mass nutrition facts

Efectiv Mass Gainer helps you reach your weight gain and muscle-building goals by providing you with ample caloric energy. With over 900 calories in each serving, this highly underrated gainer ensures that you're getting the fuel you need to power through your workouts and stimulate hypertrophy. 

This significant calorie count makes it easier for you to consume enough daily calories to gain weight and muscle mass.

45g of Protein With 17g of BCAAs

Efectiv Mass Gainer delivers a generous 45g of protein per serving, which is more than enough to support your muscle growth needs. I like that we get various protein sources as well (whey, milk, eggs) so that our muscles receive a consistent supply of amino acids.

Included in this protein blend is 17g of branched-chain amino acids (BCAAs): leucine, isoleucine, and valine, helping your muscles to heal faster.

Ironically, this high-carb gainer has more BCAAs than most intra-workout formulas!

3-carb Blend

Directions for how to use Efectiv Mass Weight Gainer

The 156g 3-carb blend in Efectiv Mass includes maltodextrin, rolled oat flour, and sweet potato. With a combination of fast-acting and slow-release carbs, this carefully thought-out formula ensures that your growing body gets a consistent supply of energy and calories.

Carbohydrates play a crucial role in weight gain and muscle growth by providing the necessary energy to support your training and body mass increases, so it’s always good to invest in a mass gainer when you’re trying to grow.

MCTs (Medium-Chain Triglycerides)

Efectiv Mass includes MCTs as an efficient energy source that also promotes muscle mass gain without contributing to unwanted fat accumulation. Unlike other saturated fats, MCTs are easy for the body to convert into quick energy, giving you workout fuel rather than fat gain.

9g of Fibre

The vitamins contained in Efectiv Mass

Many mass gainers have very little fibre because their only carb source is cheap sugar. 

This is not the case with Efectiv Mass.

With 9g of fibre in each serving, Efectiv Mass helps you to digest those 900 nutritious calories. Although fibre in and of itself isn’t anabolic, adequate fibre intake is still essential for overall health (if you want to build muscle optimally, you need to be healthy!).

Only 7g of Sugar

Despite its high-calorie content, Efectiv Mass Gainer contains only 7g of sugar per serving. This low-sugar formulation ensures that you're consuming quality calories, without the risk of sugar spikes and crashes that could potentially hinder your progress.

It also has much less fat than Hectic Sports weight gainer and is an all-around superior supplement, in my opinion.

Digestive Enzymes

Lastly, the inclusion of digestive enzymes in Efectiv Mass helps your body to break down all the muscle-building macronutrients and utilise them effectively. Ultimately, this helps you get the most out of every serving, ensuring nothing goes to waste as you strive towards your weight gain and mass-building goals.

Efectiv Mass Taste Test

The Efectiv Mass scoop size

Efectiv Mass comes in 3 flavours; Milky Choc, Strawberry Creme, and Vanilla Cheesecake. Now, I’m going to be honest, I wasn’t expecting a world-class dining experience given this gainer’s low price tag. But boy were my expectations surpassed.

Efectiv Mass might not win any awards for flavour innovation. But by keeping things simple, Efectiv Nutrition has created a really tasty shake that I actually look forward to drinking after a workout.

As any Efectiv Mass reviews from customers will tell you, the shake is much tastier than the average weight gainer. This is important when you’re consuming so many calories, as it makes hitting your macro targets so much easier.

Does Efectiv Mass Mix Easily?

As for how Efectiv Mass mixes, you'll be pleased to know that I found it easy to mix with no clumps or residue. A smooth, lump-free mixture is important not only for taste but also for getting the most out of the supplement. After all, if half the powder sticks to your shaker bottle, then you’re missing out on valuable nutrition.

To get a smooth, lump-free shake, simply add 250g of powder (3 scoops) to 500-600ml of water or milk, then shake for 30 seconds. It mixes easier than Mutant Mass Extreme Gainer, that’s for sure.

Obviously, with so much powder, you’ll need to shake vigorously as you would for any mass gainer. So if your arms are tired from your workout, you could just use a blender (you can also blend up your Efectiv Mass shake beforehand and take it to the gym with you).

What's more, Efectiv Mass mixes well, even with additional ingredients like fruits, nuts, or other supplements you may be taking. Feel free to get creative and blend your favourite combinations for a delicious, nutrition-packed shake.

Is Efectiv Mass Good Value For Money?

Honestly, for the price of this big 5kg tub, I wasn’t expecting much. I’ll admit it; I thought this gainer was going to be full of soy protein and cheap fillers.

Buy, was I wrong!

I’m willing to eat humble pie here. Efectiv Nutrition Mass Gainer offers excellent value for money. You’re getting top-quality ingredients without the premium price tag.

With such quality carbs in the form of oats flour and sweet potato, you’d think that this gainer would cost about 30% more.

And in terms of protein, we get only the best; whey, milk, and egg. Three mass-building powerhouses.

So, if Efectiv Mass is in stock, I definitely recommend picking up a tub if you’re on the market for a quality weight gainer.

When Should You Take Efectiv Mass?

Taking Efectiv Mass at the right time can make a significant difference in achieving your weight gain goals. 

Firstly, consider having a serving of Efectiv Mass immediately after your workout sessions—when your muscles are primed for nutrient absorption. 

The usage directions for Efectiv Mass

Consuming Efectiv Mass during this crucial anabolic timeframe nourishes your body with ample calories and proteins, accelerating the recovery process and supporting muscle growth.

Another ideal time to take Efectiv Mass is between meals. In order to gain weight, you need to eat in a calorie surplus, which can be tough if your appetite isn’t that big. 

By consuming Efectiv Mass as a liquid snack in between meals, you'll give your body an additional boost of calories and protein that can help you reach your weight gain goals without feeling overly full.

Finally, you can also consume Efectiv Mass before bedtime. While you sleep, your body goes through several physiological processes to repair and build muscle tissue. Having a serving of this mass gainer before you hit the sack will provide a steady flow of nutrients to support muscle recovery and growth during the night.

Should You Buy Efectiv Mass Or Not?

The supplement facts for Efectiv Mass Gainer

Firstly, Efectiv Mass is known for its impressive protein content, packed with over 45 grams per serving from a blend of whey and milk concentrate, along with egg white powder. 

This is an excellent amount for repairing your muscles and aiding hypertrophy after tough bulking training sessions.

Moreover, Efectiv Mass provides a substantial carbohydrate content of 156g per serving, with only 6.8g of sugar. The carbs come from various sources such as oats, maltodextrin, and sweet potato, all of which are much healthier options as opposed to simple sugars. 

This high carb content helps provide you with the energy you need to tackle your workouts, and also supports your overall calorie intake to promote sizeable body weight increases.

However, there may be a drawback for some users, as consuming 900 calories per 250g serving could be excessive and lead to unwanted weight gain if you’re not training particularly hard. If you’re looking for a shake much lower in calories, you could always read my Protein Dynamix mass gainer review for a different option.

Ultimately, the choice of whether to invest in Efectiv Mass is up to you and your goals. If you're wanting to build a lot of muscle mass, this weight gainer is for sure an excellent choice. Thanks for reading my Efectiv Mass review!
