I've been using Optimum Nitration Glutamine for as long as I can remember. It is a clean supplement and is effective, any supplement that I use and can order with ON I do. I like the quantities it is sold in and the price is manageable

This has helped my workout recovery immensely. I can go heavier, train longer, etc, and not have to worry about not functioning the next day. Heck I take this instead of an anti-inflammatory half the time.

Odered it in August 2016 and bodybuiding.com sent me a package of this product with the exp. date September 2016. Slow delivery, and I couldn't use it all untill the end of the month, so it was a total waste of money.

It does the job it's suppose to do. I feel less sore the next day after a grueling workout. But I don't completely rely on it.
