Pro Series

This is what I use as well. Love the taste and not super expensive.

Not sure about affordable, but I use syntha 6 or muscle milk. Buy the big jugs from Amazon, cost $35-$50ish per jug and lasts about a month. I prefer mixing with oat milk but water, milk, soy milk, etc will all work just fine.

PS just read an article about high lead and heavy metal contamination in a lot of protein. Syntha 6 came out as a recommended brand. Muscle milk pro had higher lead levels. Ugh.

I like Muscle Milk Pro Series Powder, specifically the Intense Vanilla flavor. 2 scoops dissolves into a 14oz shaker bottle easily and slams back in no time. I've tried a lot of flavors all along the price spectrum (my kids call their multivitamin protein vitamins because they recognize the character from a fruit pebble flavored one) but Muscle Milk Intense Vanilla powder is tasty and inexpensive

Everyone trash talks Muscle Milk, but their Extreme Vanilla flavored Pro Series is my favorite flavor

Muscle Milk Pro, because it tastes the best in my opinion after trying most of them and it is also fortified with other really beneficial vitamins and minerals.

Optimum nutrition gold standard, it’s what I use most of the time. I’ve started having the muscle milk pro series 50g before going to bed as it’s a nice mix of milk protein isolate, casein and some whey for only 310 calories per 50g protein serving. Both of these mix fine, I use water and a shaker bottle. But really not much beats ON gold standard for whey. Competitors either are cheaper but taste worse/have fillers/use inferior low anabolic types of protein like collagen/not 3rd party tested/are more expensive.
