I'm on my trib cycle currently and taking estrogenex to help block the estrogen, I'll cycle back on Novedex XT by the end of next week. I noticed a boost in energy for a couple days and then my body got used to it, so I didn't really notice the boost after that. It also messes with your emotions a little, at least it did for me, I found myself rationalizing things I typically don't rationalize about lol. I had trouble going to sleep the first time I used it due to the boost in energy, that's why you take it 'right' before you're about to fall asleep. I also took 2 in the morning every other day.
I also found that this didn't mix too well with Cyclin by MHP (a ZMA supp with other growth factors). I tried those two before bed and something about the two didn't go to well and I couldn't for the life of me fall asleep, that was very frustrating. So I stopped the Cyclin until I cycled off of the Novedex.
