I take maca everyday in the morning but I had to stop taking it when I was abstaining from masturbation, and I tell u why. When I take maca, and if u get horny, u get horny really really quickly, i mean, if u shoot a trigger without maca, maybe u can get conscious and stop the horniness; but when u take maca, it seems that it s so fucking diffficult to stop it, aand I ended a lot of times masturbating . This is my personal case. That s why i stopped taking maca, it was making it even more difficult to stop from PMO.
I reccomend taking maca but as Fappy says, it s not gonna help in anyway for PIED
