Good info but before everyone starts loading up on dostinex, a little reminder that this was touted by the Life Extension organization (of whom no one is directly liable) as a "smart drug" back in the early 90's. People started popping the recommended dose of 1 mg 2x's day. This resulted in reports of nausea, vertigo, depression, insomnia, hypotension, exhaustion, tremors and paranoia.
Meanwhile, ginsing lowers prolactan. (Which may the reason for its reputation as an aphrodesiac).
Proceed with caution.
