MuscleTech Mass-Tech Rocks !!!

8 months ago
I have now tried both chocolate and vanilla. For chocolate I’ll give it 4/5 stars and for vanilla 5/5 stars. The chocolate tastes of both coffe and toffee. The vanilla is straight creamy and rich it doesn’t have that stingy vanilla flavor rather it has that ice cream vanilla flavor which is great ! Chocolate however is good and it comes with other underlying flavors like I mentioned in the text. These are great gainers no doubt, it hasn’t stopped me from using and mixing the gold series double rich chocolate with mass-tech chocolate and still taste awesomeness !!! In the pictures I have put a kithen knife in each of the buckets for correct measurement and reducing pockets in the scoop.
