I had just finished my 6 week cycle of 1-T from Primordial, and I have nothing to say but possitive feedback from this stuff. My bench PR sat at a 215#, and with extensive training moved it up to a 245#within the first 3 weeks. I found myself waking up with a great attitude, and even better moving heavier weights a lot easier than I ever have before. I was a little sketched out about using this product at first. I weighed in on November 21st at a 150 pounds, and with my diet in check(300 grams of protein, around 400 grams of carbs a day) I was gaining almost .5 lbs a day and ended today weighing in at 167.5 pounds. I just broke into my recovery stack today and really excited for the mornning wood associated with Sustain. Thought I would share my experience with you guys.
