I personally use Vitamin Shoppe's Bodytech because it's not too expensive (as far as protein powder goes) and tastes great. I stick with the chocolate flavor. I also use their Cassein powder. Plus I eat chicken, eggs, beef...all that kind of protein from solid foods.
I use the Whey as a hopefully fast metabolizing protein after working out, and the Cassein as a slow metabolizing protein when I have it with a snack during the day and before bedtime.
On a semi-related subject, I combine the whey with CytoCarb2 that I get from Amazon for my post-workout shake. It's tasteless, affordable, and scalable depending on how many scoops you put in or need.
Keep in mind I haven't made much progress in two years. I'm hoping it's because I have low T and almost no Estrogen. I don't feel a lot different but from December 20th (when I started TRT) to February 1st (43 days)...I went from 195 lbs, 13.9% bodyfat to 198.5 lbs, 12.9% bodyfat. That's a 1.5 lb decrease in bodyfat and almost a 5 lb increase in lean body mass at the same time.
***PLEASE let me continue to make progress. I've worked so hard for so long to get nothing out of it, I've got to have some muscle karma coming my way.
