A: Best bulking results I’ve ever had was with this product. So yes.

**Q: How long does 1 tub (4.35kg) last?**
A: Hello I only take 1 scoop at night when I've trained so 3 times a week lasted me a good few months you don't need more than 1 small scoop

**Q: How is the vanilla ice cream flavour in terms of taste??Ive had some 'vanilla' flavours in my time that were absolutely terrible and made me gip**
A: Salaam i remember the big toughened foil bags maybe they had more powder in them.  But this one stop is brilliant good for vegetarians no bovine or gelatine in it. Personally i only use 1 scoop it's more than enough.  And in milk it tastes really nice not harsh or chemical taste. I did my research before buying it's  much better than the other brands even those charging much more than reflex. In Shaa Allah you'll get good results with this.
