Wow, it never really crossed my mind that beta-alanine would be unsafe in any way. Primarily because it does not need to be used consecutively to be effective. If you work out three days per week for example, consuming 5,000mg of beta-alanine 45 minutes pre-workout should be sufficient. I didn't think such low doses would really be unsafe in any way, but it is a rather potent supplement.
Will IronMagLabs be producing a beta-alanine supplement?
