Awesome Protein + Awesome Flavor
By Killian W. on August 21, 2013
Flavor Name: Chocolate Milkshake

I recently took on a much more intense regimen of Muay Thai 5 days a week, and am now in the best shape of my life. I feel amazing all the time, even when I’m so obliterated I can’t move. Syntha-6 really helps with adding solid muscle, especially when worked into a stack with a high quality creatine (like CRUSCH: Ultimate Tri-Phase Creatine, which is what I’m using right now). It also has the best flavor of any protein out there… the chocolate milkshake actually tastes like a chocolate milkshake. And it mixes incredibly easy with a Blenderball, and doesn’t get all clumpy. I use mine between breakfast and lunch as a meal replacement, and also as a post-workout, and it gives me everything I need. Great product.

Delicious, Nutritious and HUGE

This is the first protein powder I’ve purchased on Amazon. I have purchased protein powders in the past from another site and they were pretty good, but I figured a change of pace is always a good thing so I went for the Syntha-6 five-pound container of Vanilla Ice Cream flavored protein powder.I’ve been using it regularly for a month and I am extremely happy with my purchase. I Whey Proteinhave noticed an increase in energy when I use it to mix up a recovery drink for during and after my cardio workouts. I do P90X workouts and this stuff is perfect for mixing up with a smoothie after I do one of the weight routines.This stuff is so delicious it’s hard to believe it’s healthy. I look forward to my workouts partly due to the fact that I get to consume this stuff. I have mixed it with water in a plastic water bottle and have had no trouble with clumping (separation of the powder and the water). I have also used the powder in fruit smoothies and it makes them even more smooth and delicious. It also has a really great aroma and tastes and smells very much like vanilla ice cream.The five-pound container is HUGE. I use roughly a scoop a day and I’m sure it will last me for several months. The only downside I can see for buying such a big container of the stuff is that I might get tired of the flavor after a couple months, but I don’t foresee that being a problem with this stuff because it is THAT tasty.
