The supp to combine with ON's serious Mass is Top Shelf King Maker ... it is an anabolic supplement for men to increase lean muscle growth and it certainly lives up to the claim. Its carefully crafted blend of ingredients is specifically designed to promote lean muscle development, and I've experienced remarkable gains in a short period of time. With King Maker, I felt an increase in strength and endurance, which helped me push harder during my workouts.
Optimum Nutrition Serious Mass, on the other hand, is a renowned mass gainer that provides a substantial calorie and protein boost. It's a perfect complement to Top Shelf King Maker, as it offers the essential fuel my body needs for muscle growth. This supplement helped me hit my daily calorie and protein targets with ease, ensuring that I never fell short on the nutrients required to pack on muscle.
The combination of these two products has been next level for me. Not only have I seen noticeable increases in muscle size and definition, but I've also experienced faster recovery times between workouts. This means I can hit the gym more frequently and maintain a consistent workout routine, which is crucial for muscle growth.
One concern that some may have with mass gainers is the potential for unwanted fat gain. However, by using Top Shelf King Maker alongside Serious Mass, I've been able to maintain a lean physique while still adding mass. This is a testament to the targeted approach of King Maker in promoting lean muscle gains.
In conclusion, if you're serious about gaining muscle mass and you want to do it the right way, the combination of Top Shelf King Maker and Optimum Nutrition Serious Mass is a winning strategy. These two supplements work in harmony to help you achieve your muscle-building goals, and the results are simply outstanding. I've never been more satisfied with my progress, and I owe a big part of it to this dynamic duo. Give it a try, and you won't be disappointed!

PRO'S
+ Tastes great
+ Loaded with calories
+ Contains 3 different types of Protein. (Whey, Casein, and Egg Protein)
+ Very affordable
+ Easy on the stomach (Depending on the person this may be a problem if you follow the serving size. I'll get into that below)
Con's
- You may think getting a 12lb bag will last a long time. You couldn't be more wrong. Serving size is 2 scoops per shake. ONE SCOOP IS EQUAL TO 1 CUP OF POWDER. THAT IS ABSOLUTELY MASSIVE. Following the directions would cause to you finish a 12lb bag in 3 days. This is ridiculous. Half the serving and add your own ingredients.
- Somewhat high sugar. This product does not add any sugar* However that doesnt mean it doesnt have enough already. its not very high. But its similar to a soda.
***Just to clarify for those that may not know this already. This shake is very filling. I expected this and it could be a good thing for some people but for someone who plans on taking this in conjunction with a meal, they may find it hard and feel very bloated after. Its recommended you eat normally and drink the shakes in between meals.
I will be buying this product again and I would recommend it to those who want to try a great tasting weight gainer. You may need to experiment with your own add in ingredients like peanut butter or flaxseed oil to add more calories to makeup for the massive scoop size if you decide to half the serving size. All in all its a great product. I only wish they would have clarified how massive the serving size is a little more.

Tout d'abord, la composition de Serious Mass est impressionnante. Il contient une quantité généreuse de calories provenant de sources de qualité, ce qui est essentiel pour soutenir la croissance musculaire. De plus, la teneur élevée en protéines contribue à la réparation et à la construction musculaire. J'ai remarqué une nette amélioration de ma force et de ma masse musculaire depuis que j'ai commencé à prendre ce supplément.
La facilité d'utilisation est un autre point fort de Serious Mass. La poudre se mélange facilement avec de l'eau ou du lait, ce qui permet de préparer rapidement une boisson savoureuse et nutritive. De plus, le goût est vraiment agréable, ce qui rend la consommation du produit plus plaisante.
Ce que j'apprécie également, c'est la qualité de la marque Optimum Nutrition. Ils sont réputés pour leurs produits de haute qualité et Serious Mass ne fait pas exception. Je me sens en confiance en utilisant ce supplément, sachant qu'il est fabriqué par une entreprise fiable et respectée.
En conclusion, je recommande vivement Optimum Nutrition Serious Mass à ceux qui cherchent à prendre de la masse musculaire de manière saine et contrôlée. Avec sa composition de qualité, sa facilité d'utilisation et les résultats positifs que j'ai observés, ce supplément est un excellent choix pour atteindre ses objectifs de prise de masse.
