I use supps and they have worked well.

Tribulus Terrestris
I’m personally a huge fan of this herb. In this human study, 750mg Tribulus Terrestris extract (112.5 mg of protodioscin) supplementation daily reduced the prolactin levels by 60%, from 17ng/dl to 7ng/dl in just 28 days (R). It also increased DHEA and DHT dramatically.

Zinc and B6 also help.
