Hey I wish I had the answer for you too. Maybe some protein powder would be good now and then for me, but I feel like just eating does the trick. I'm noticing size-able gains with just a good work out 2-3 times a week and a romantic relationship with my kitchen
I figure, as long as you look into foods and their digestion rates compared with all sorts of things like protein levels, carbs, glycemic index, ph, and how they combine with other foods- and space it all out with time intervals to match... and you got yourself a great formula.
For me, I just can't afford vegan protein powders. Maybe cause that means I could buy something for my car instead. But yes, expensive stuff. I could be looking in the wrong places too. I'd love to have hemp protein in a 5 gal tub again!! Dream come true. Also a vita mix! -An even better way to get your "QUICK" protein FROM FOOD, which if you read say, the 80/10/10 diet book (which I would recommend), you might feel the same way. There are definite convenience factors that you'll have to analyze your lifestyle to decide for, but if you can, I'd build up that food relationship, and cook/ prepare and eat for your muscles.. which of course would also be for your general health. Let's not forget that you don't need that much.
Last notes, liquified smoothies with proteinatious (it's a word in my world
goodies in it right after a work out= awesome. I don't know about y'all, but what I do in place of making sure I have proteins in me of different rates to absorb some level at most times- is to just eat a lot. I don't feel very abnormal with it either. But Like I said I love food! So there's usually a giant sandwich waiting for me, and I eat as many meals as I can. Usually when I'm at home, one meal gets stretched into 2 or 3. Cause when you eat while you cook, or you make something else before the other thing your making finishes because it all looks so good... well, it's one way to go. I'm a fan. But hey, at least believe me when I say, what I'm doing is working for me. And I don't take anything. I just lift and eat aside from everything else I do with my life.
