Hello, Endura Mass is a gaining supplement.It is totaly useless and wast of money.It doesnot helps in gaining weight.Endura Mass supplement advertising good on TV but in reality there is a lot of difference.The flavour was ok and it comes in a variety of flavours like chocolate, strawberry etc but donot help gaining weight.This nutritional supplement rarely causes any side-effects.Some of the side effects from prolonged use of this supplement are-Fatty liver disease, loss of libido, loss of appetite, unwanted fat in body etc.Its only tastes good but has no effects, all the advertises shown in television are totally fake.It also doesnot meet its given nutritional ingredients.You must not buy this product its very cheap price and low quality gainer.I suggest you not to use it. Thanks.
