Rated 1 out of 5 by from disappointed No noticeable effect, even with maximum dose of 3 pills. Swanson's Super Strength L-Arginine 900mg product is much better.

Rated 5 out of 5 by from Larginine I like getting a 1000mg at a time. They're easy to swallow and they don't get soft like some arginine does when it's humid.
