If you start hearing your heartbeat when your trying too sleep on your side up your water intake. Beast was so intense i'd be trying to sleep and my bp would keep me awake, buuuut i was taking 4 a day..... I loved it, god i miss the beast. You're going to get some awesome results w/ that and test, keep us posted.
I should add that my bro is finishing up his beast only cycle and he is the heaviest and strongest he's ever been. He's doing 1 arm rows w/ 120's and incline w/ 110's. he's 47 and still has a full 6 pack and runs 5 miles a day and only been doing serious weight training for 4 years. before beast- 185 at 6ft. after beast- 207.
