Update: Officially been taking the stack for a week and I've noticed a lot of changes. My sleep is better, I'm falling asleep earlier and having and easier time sleeping, my endurance is way up at the gym, last time I remember having endurance like this was when my doc had me on hGH to grow taller. Also libido is so sky high 24/7 it's almost like a constant hard on, which can actually get quite annoying sometimes. Have also been able to reduce my caffeine intake which is something I've wanted to do for a while. On the downside however, I am constantly, extremely hungry!! Like nothing can fill me up, I'll down several thousand calories per day no problem! I already had a big appetite, but this is ridiculous! Anyway, I'll update again soon
