Other than the Humanogrowth I have used the same combo plenty of times with Optimum Whey. I think the Optimum whey is a quality product but I liked the myofusion better. Maybe the different types of protein digested more slowly or absorbed more fully, I'm not sure but I gained 7-8 pounds while taking this and that is better than what I have experienced with the regular whey combo.
Taste/mixability-fine, I used chocolate and I used a blender anyway so no problems.
Effectiveness-it worked for me and I certainally qualify as a hardgainer
Value-for protein priced at this level I think it is one of the best. Cheaper proteins and supplements in general I have tried with high hopes in the past and generally regretted it.
Overall a quality protein powder that I will purchase again.
