    Product not same as first bought

    I wouldn’t recommend (Mass gainer 3) reasons are follow:
    I train high intensity workout where high Crab used for after burn energy recovery. This product I used for last four months, I found the first cycle batch was good and packaging was nicely sealed with foiled lining inside.
    After first batch the last three bags, I notice the product inner package was change where the first bag had food foil lining thereafter three bags I bought weren’t same package and did not provide the same level of crab. My recover rest days were gone longer as this product weren’t doing anything to repair. I think crab been taken from very high source of sugar.
    I’m loyal customer to decathlon all my sport gear are bought from their store or online and I would highly recommend to anyone who are looking good quality equipment or gear.
    Perhaps decathlon need to re inspect this mass gainer 3 as it’s not really working.
    I do appreciate guys from decathlon bring great affordable sport for everybody.
    Many Thanks, J-Junaid

    Buen sabor

    Yo lo utilizo durante los entrenamientos, tanto de bici como gym o running. Muy alto en azúcares para fuera del entreno. Con leche queda muy buen sabor.
