Bought the chocolate flavour because of the reviews but it tastes awful. Tastes nothing like chocolate at all. Wish I got vanilla.

Superior Taste with a Hint of Extraordinary

Review by Nikolay Voronkov on Jan 12, 2021
Once upon a time, there was an athletic but not lean guy who really wanted to increase his protein intake as his goal was to bulk up & add some muscle mass. He knew not of what sort of shake he should go for but one thing was for sure, he knew it needed to taste badass & have all the right things for muscle growth. He was inexperienced and tried many varieties of shakes from different brands & let's be honest they all tasted pretty "urgh" when it came to crunch time apart from Serious Mass. The only company I trust to deliver an outstanding taste alongside everything I need for muscle gain. Try it out because drinking something every day is gonna get boring but at least the taste will leave you satisfied.

Tastes amazing

I wanted to gain weight so I bought the chocolate flavour serious mass, I just started a week ago but I gained like 2 pounds already, I just mix it either with water or milk. Go for it, for more gains.

Ziemlich gut

Review by Jiahua on Nov 17, 2020
Habe mir Erdbeere, Vanille und Schokolade geholt. Erdbeere ist sehr gut, Schokolade auch ganz gut, Vanille erinnert ein wenig an Babynahrung, ist aber trinkbar.

Review by Anouk on May 22, 2020
Ich habe Vanille genommen, da es kein Schoko mehr gab und es schmeckt extrem eklig. Ich habe bei vielen gesehen, dass die dadurch zugenommen haben, aber wegen dem Geschmack kann ich das einfach nicht trinken. Ich habe es jetzt schon ein paar mal versucht, aber der Geschmack ist einfach nur schlimm. Ich weiß nicht, ob es nur Vanille ist aber ich kann euch auf jeden Fall nur davon abraten Vanille zu kaufen. Schade, da ich gehofft hatte dass das Produkt funktionieren würde.
