In 4 days that I took this, my body started feeling great. My shoulder is always inflamed and the muscles just won’t activate and I found out that estrogen and progesterone receptors are in the rotator cuff. BH4 is essential to make a lot of hormones. After taking it my shoulder stopped hurting and my body wasn’t inflamed in the mornings. My outdoor allergies went away too.
