Tastes amazing

Review by Nur Sherif on Sep 15, 2020
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.

Meer dan tevreden

Review by Koen on Apr 24, 2020
Nog nooit eerder gebruikt, ben meer dan tevreden. Bananen smaak is werkelijk net een Milkshake van de M*D*****s. Tip: Doe het met wat melk/ water èn ijsklontjes in de blender en je hebt een milkshake! Top product.

Als nog niet weet hoe de verschillende smaken zijn raad ik aan om de banaan te nemen (Als je banaan lekker vind) deze is lekker zoet en drink je zo weg.

Smaak: Banaan is een goede aanrader! Het lijkt erop alsof die ook minder klont dan de smaken chocola / aardbei. Veruit de lekkerste!
