500 MG but I’ve only taken it once a week so far. The effects seem to hold for that long. As with anything I am not positive the effects will continue but I can tell you something good is happening.
I’ve read some of Mew’s posts where he has had luck with L-Arginine but uses it sparingly as to avoid the dropoff effect that we all fear. That’s why I’m only going to take it a few times a month or when I feel I need it (could be less than a few times a month) as long as I’m having positive results.
I do also seem to have more ejaculate and an urge to come with good feeling. Trying not to overdo it though…
Read some of the sticky’s on this.
