Heb de vanille gekocht, goede smaak maar mixt niet goed in shaker. het is aanbevolen om dit te mixen in een blender. werkt wel !

Wel goed

Review by Hilary on Oct 8, 2019
Effectief. Ik drink het met melk voor een extra effect. Verder heb ik de smaak vanille, smaakt lekker. Alleen wel heel zoet als je het alleen met water mengt.

The Best Ever !

Fantastische gainer

Review by Tom on Jul 17, 2019
Na verschillende gainers te hebben gebruikt kwam ik uiteindelijk terecht bij optimum nutrition. In mijn tijd in New York kocht ik altijd de pro gainer. Eenmaal terug in NL kwam ik erachter dat die niet te krijgen is in Europa. Op zoek naar de vervanger kwam ik bij deze uit en deze is zelfs nog beter. Qua smaak iets minder qua werking beter. Top product goeie werking en prijs.

Beste Weight gainer!

Review by Rudi on Jul 15, 2019
Ik gebruik serious mass al jaren! Vooral de chocolade. De aardbei is overheerlijk maar wel aan te raden om in een blender te mixen. De andere smaken mixen perfect in een shaker.

Lekkere shake (vanille) klontert nauwelijks en doet wat hij moet doen.

Review by Jasper on Jul 3, 2019
Prima product. Ik heb zelf niets om aan te merken al vindt mijn omgeving de geur heel sterk.

Very good it works for me.

Review by Bas on Jun 23, 2019
The taste is not so heavy. Strawberry is nice.
