*by  on Reviewed in the United Kingdom 8 February 2018*

Excellent stuff, i have done my webwork checked out levels combo's of minerals and bcaa's through to creatine mixes this stacks up seriously good easy to mix good strong flavour but not sickly easy to consume on an empty stomach and has nice milkshake consistency. can easily be drank in the morning and pre workout and after the workout again great levels of bcaa and creataine as a stand alone this can save you money as it contains everything you need in one supplement and it really has shown results after consumption after a good workout. can only recommend this as it does exactly what it says. any questions drop me a message
