Luelinks man I ran this with my Natadrol and it was good. I can't tell you exactly what it did compared to the other stuff but I know that I was at 8 caps a day of nata and when my PSarm ran out I noticed the difference. Strength, aggression and recovery all took a small hit when I came off of it and was on Nata alone. I wish I had run it standalone to give you more details but there are a few Logs out here for it if you search. Good results. I would like any natty product run 2 bottles worth. You will feel a difference day 1 though. It seems to be relatively quick acting regarding aggression and Alpha Male.
