Pretty damn good

Review by John Silvestri on Jun 19, 2022
I’ve been skinny my whole damn life. And I’ve been taking this stuff consistently for a while and I’ve gained a good amount of pounds. It is affordable and taste pretty good. The only thing is the little balls float to the top if u don’t shake it well enough. I drink this stuff daily and I haven’t got bored or sick of it yet. Great product. Thanks optimum nutrition.

Best Shake EVER!!!!!!

Review by Jane557 on May 20, 2022
Not sure why people don’t like the vanilla I love it!!! Just now as excited to try the other flavours of vanilla is said to be the worst ha! I absolutely love this shake and how much calories I can get from just one drink!! I struggle to gain weight (appetite and fast metabolism issues) and this is THE best I have ever tried. I love how it does not have all of that nonsense thickening agents (guar gum, xanthan gum, etc) that makes protein shakes taste terrible! I hate the slippery and heavy texture it gives so I am absolutely thrilled that I found this one that has none of those nasty ingredients! Please don’t ever change the formulation it’s perfect!!
