Used this for 4 days and now I possibly have myalgia

Posted by 5208602616016868114 on Jun 24, 2013

Took 1000mg before bed for 4 days and experienced severe muscular pain after about 3 days, I stopped using Tryptophan right away. Now, 10 days later and the pain persists and is continuing to get worse. Do intensive research before taking this supplement.
