So, I'm reading through some posts on BlackHairMedia, and read that a girl used a progesterone cream and mixed in two L-arginine pills for the last two weeks before her cycle and grew a lot. Not sure what else she may have been doing along with it, but I was wondering how legit this sounds. Can L-arginine even do anything if it's not ingested?
