Ive used this for about 2 weeks now, haven't touched any sauce for over a year and a half now so I decided to go waste some money and see if supplements actually did anything 2 years later (because they sure didnt back when I was starting out like a lot of you 5-6 years ago............other than a mental gain) and I have to say this shit isn't too shabby, but who knows maybe its mental. I do feel some added strength though. Pumps are whatever. Same as usual. dont see a difference in that.
