Great stuff!!! I've increased muscle mass and strength whilst keeping body fat down. My appetite for big lifts is insatiable, down the gym i'm completely in the zone. Side affects are increased aggression and libido, don't have a problem with the latter but it's odd getting angry at things that wouldn't bother me normally. I'm always hungry now and have to watch my diet a bit more closely making sure sure i snack on the right things (protein bars are good for this) Animal test is easy to use (just swallow the pills and you feel the results within 40 mins) and very effective. I recommend it to anyone serious about getting bigger faster.
