Review by MIke on May 10, 2023
I bought a 5lb tub of Banana and a 5lb tub of Chocolate...mixed them together and Ive honestly never tasted anything better in my life. I had 4 shakes yesterday because it was so addicting. It taste exactly like fudge bombs. I couldnt be happier or look forward to a shake more. Both flavors are excellent alone but together theyre unreal. SO SO SO GOOD!!

Good product!

great product , taste well

Blends Super Easy

Review by Al on Oct 12, 2022
I've been using this protein powder for over 8 years. It';s my breakfast meal replacement. I've tried most of the flavors, but my go to is vanilla, it blends best with fruit juice. I do 2 scoops with 16oz of juice, I also add frozen fruit and half a banana. SYNTHA-6 is such a fine powder that it can easily be mixed in a shaker cup, when a blender it's available. I tried many protein powders before landing on SYNTHA-6. I like the multiple proteins and absorption rates, it gets me through the morning and helps me with the energy I need to do my physically demanding job. Prices are rising now, like everything else, but I will never stop drinking this!

Great product

I actually really liked this protein powder! The taste is AMAZING!!! Tastes exactly like chocolate cake batter! The ingredients were a little iffy because it contains dairy which some might not like but I didn't really mind. I used this after working out and it made my body feel a lot better and less tired. Would definitely recommend

Great flavor!

This protein powder is so smooth and not chalky like others I have tried in the past. The Vanilla icecream flavor is delicious and actually reminds me of cake and it goes great in my smoothies. I love the high protein factor and this is a great all around protein .

Good Taste, Good Product!

This protein powder is one of the better ones I've tried. It has a good taste andd texture. It is a bit heavy though and calorically doesn't quite fit with my lifestyle. However, it's a good powder, very filling and worked best as a complete meal replacement instead of a sort of snack. I would buy, and would recommend.
