I used to only use Optimum Nutrition gold standard whey but recently Ive been using isomorph 28 from APS nutrition. I really like the flavors and how it blends in water. Definitely prefer an isolate and i got a discount too from samedaysupps which is always great
I wasn't a fan of Muscletech. If i was to go for a whey concentrate i would just go with ON gold standard whey. Samedaysupps even has a discount on the 2lbs right now. Its like buy 2 and get $10 off. So that puts you at $50 for 4lbs of protein
I really like scivations tend. The pineapple flavor has been a long time favorite of mine otherwise i also like hyper amino from gaspari. The blue raspberry is very refreshing.
