I'm not shooting down DAA because it's proven by blood work and published studies. I tried it a few times. The stuff leaned me out and I had great strength gains but I found at 3gms per day I had increased anxiety. I decreased the dosage and believe it or not I responded just as good. I decreased it to around 1gm per day and still had the benefits but I still had slight anxiety to show up but only further into cycling it. I was taking the DAA powder from Nutraplanet during this run...my first run however, was Testosterone Conversion Factor-1 (TCF-1) from Primordial Performance and I preferred it because I cannot recall having the anxiety issue with it.
Anyhow, try a keyword search either on this forum or google for "blood work triazole activate xtreme" and see what it brings up. You may be pleasantly suprised, it too is backed by blood work and studies. Right now it is hands down my favorite test booster combo (Triazole @ 2 caps/day and Activate Xtreme @ 4 caps/day). I am stacking it with L-Carnitine L-Tartrate @ 2 gm/day and the results are simply amazing. I am leaning out, have gotten much fuller muscles, big increases in strength, gained muscle mass, increased libido, increased endurance, wicked sense of well being and confidence and crazy deep sleep with vivid dreams. I feel like a million dollars on this stuff.
Just my personal experience.
