At age 45 I am running this stack to boost my test levels.I started the stack on 5/1/12.The first thing that I noticed was how fast Intimidate kicked in.On day3 I woke up with a huge libido increase in the form of morning wood.I think it is stronger then other DAA products and I have tried a lot of different DAA products.I do not have blood work to show results but things that I have noticed from this stack are oily skin and slight acne in back and face. I experienced an increase in appetite.I dosed Intimididate at about 10pm and I would wake up at around 2-3am hungry and raiding the fridge.I know some people here at AM had sleep issues with Intimidate but the only issue I had was hunger and I was able to fall right back to sleep.I am about to start bottle 2 of each and I will be adding Triazole.I think IForce really nailed with Intimidate and anybody who is running PCT or if you are just doing a natty stack,You need to include Intimidate.You will not be disappointed.
