I would advise against it. If you double up on AI you will wreck your joints. Your brain also needs small amounts of estrogen for protection. Be careful with your brain, it is my second most favorite organ. The up side is diminishing returns at more cost. If you want to pimp out your test booster, then add some bulk Maca, Fenugreek, maybe even some Fadogia. Mix some of these into your shakes. Think about adding 3 grams per day of Taurine for the run, this works! Forget about DAA, this turned out to be a bust.I'm thinking of stacking 2 test boosters , animal stak and brawn nutrition complete test. they share some similar ingredients, stinging nettle root and fenugreek. Not sure how beneficial it is to double up on those , also They both have Aromatase inhibiting properties which are different but again doubling up on an AI. Any thoughts?
Good luck and happy lifting
