A few years back I was in a nasty accident and spent a lot of time in rehab. I couldn't exercise, got depressed, divorced, the whole routine, and of course I packed on the pounds. I tried all sorts of brand name products and did the same as you, blew a lot of cash. I am in my late 50s and was convinced that I was stuck! Then I started taking cissus quadrangularis - in big doses (4 servings, 2 grams per serving, mixed with dark cocoa in chocolate whey isolate as this stuff taste like s**t). The only other supplement I take regularly is R+ALA (alpha lipoic acid).
I adopted the eating routine in the Warrior Diet, the food recommendations from the Primal Blueprint, and the exercise routines laid out in Convict Conditioning. Now I eat about 3000 calories per day, up from 2200 when I gained a lot of weight. In the last year I dropped over 50 pounds! Crazy. This spring I decided to make the effort and research the supplement industry. My conclusion - the same - there is so much bull and crap. A company with a good research program can only develop a product or two a year - at best. Most of it is just hype and bad science. I chose only two company's product lines - PES and USP Labs. I still buy other products from other companies once in a while (I really like Southland's Revamp) ... Right now, I am taking USP Labs super cissus caps to work for my joints; and to attack that last 10-20 pounds of stubborn fat I just started the PES stack (Alpha T2 and Erase). It will be interesting to see what happens. All the best, R
