I've started with 500 mg last year and it was too much for me to start with. It upset my stomach, so i had to take it only with empty stomach in the morning. It also gave me acne and stopped my period, because i was taking maca throughout the all cycle. Now i'm taking it to help with dhea, but i'm starting with 250 mg in the morning, along with anti dht herb, and i stop some days before and during my period. Try stopping a couple of days before your period come and check if it happens again.
