It's just WPC with creatine and BCCAs mixed in. Not a bad formula as they're the 3 main supplements that actually do something. However it does seem a bit expensive for what it is. Either way, it's your money and you're paying for convenience of not having to buy the supplements individually.
What does worry me is the sugar content though. 24.7g per 100g. So a quarter of the tub is just sugar, which you can get for like $2.00/kg if you're deficient in sugar lol.
