TOP 5 – Supplements for Building Muscle Mass
How to build mass and gain lean muscle mass.
The market for mass and muscle building supplements is so wide that it is difficult to choose the best product.
I decided to conduct a thorough analysis and test the best mass supplements on my own skin.
Since I have been working out in the gym for years, I have already had experience with many products supporting training. I also analyzed the composition and effects of dozens of supplements to present the best available gainers, protein supplements and comprehensive supplements for building mass.
When creating the ranking, I paid attention to such things as:
- Product composition and the amount of active ingredients in a dose
- Independent scientific studies that determine the effect of ingredients on building mass
- My own experiences and effects obtained when using supplements
- Opinions of trainers and experts in the field of dietetics
- Consumer statements on moderated internet forums
Why do I need a mass gainer?
Sensible and planned supplementation with properly selected supplements can significantly speed up the achievement of set training goals and increase the effects of exercises.
The speed of building muscle depends on genetics, diet, training, regeneration and supplementation. Different body types (ectomorph, mesomorph, endomorph) have different predispositions to building muscle. A proper diet rich in protein and calories, intensive strength training and proper supplementation are key here.
Below are 5 best supplements for building muscle mass:

Summary and my review of Optimum Nutrition Serious Mass
This typical gainer is one of the better choices when it comes to effective muscle mass building. Proven formula and good composition. The product was placed in 3rd place due to the fact that the effects that can be achieved using Optimum Nutrition Serious Mass are smaller than in the case of products from higher places. In addition, the use is a bit less convenient. Within a month we need 2 packages of the product, which generates quite high costs.

- Only natural ingredients
- All in one – we don’t need other supplements
- My personal assessment of the effects and effectiveness 8/10

Muscle Mass Supplements Out of the Ranking
Turkesteron
Turkesterone is a natural plant steroid, also known as ecdysteroids, that occurs in plants such as ajuga turkestanica. It is often used as a dietary supplement to support muscle growth, improve endurance, and increase physical performance.
