Isagenix IsaLean Pro Shakes are meant for meal replacement but I used the two samples as protein supplements. Since I only used the two samples sent to me, I cannot vouch for long-term use. However, in this video, I review the nutritional content, ease of use, taste, and consistency. I was given samples so I did not provide the cost-per-use.
