D-aspartic acid

[tryingtoimprove]

How has this supplement worked for you? I notice I get really irritable and cranky when I take it. What's your opinion, does it work?

It's good at restoring/raising natural test levels. IMO, this is the only OTC test booster that is worth the money. Your sides of being irritable and cranky are prob due to increased test levels. I personally like this stuff.

I am using D-Aspartic Acid by primaforce and I have been on it almost a week, I feel that it is working, I also am having some irritability issues, but overall feel like it was worth it.
