I use x2 tsp of psyllium husk and x2 tab Optimal Nutrition banana or chocolate - whisk with 600ml of no sugar Alpro soy milk, top-up to 1 litre with water and the result is a smooth yummy milkshake 🙏

I've been using that for the last 14 years lol. I remember a really long time ago someone on reddit went through a bunch of different protein brands and good standard had the actual amount of protein it said. And muscle milk had like nothing lol but I assume that's changed

Agreed. They used to sell s'more as well, and it would go on sale. Haven't seen that in years in costco.

I used to do the Gold Standard Whey Protein and liked it pretty good. Then found the line of products by Transparent Labs and prefer them now.

This is my preferred protein powder. I enjoy the flavor as much as protein powder goes.

Yeah, backne seems a bit too much. I take NP Gold and it’s one inexpensive protein that gets all the basics right.

I balance between best reputation and least gas. So, having said that ON works for me.

The cookies and cream flavoured casein protein from Optimum Nutrition tastes heavenly, like a creamy oreo shake. The whey version tastes terrible though
