in the description of this product they say that it releases gh , is it pretty much like ghb or is it different?

Bromocriptine (broe-moe-KRIP-teen) belongs to the group of medicines known as ergot alkaloids. Bromocriptine blocks release of a hormone called prolactin from the pituitary gland. Prolactin affects the menstrual cycle and milk production. Bromocriptine is used to treat certain menstrual problems or to stop milk production in some women or men who have abnormal milk leakage. It is also used to treat infertility in both men and women that occurs because the body made too much prolactin.

Bromocriptine is also used to treat some people who have Parkinson's disease. It works by stimulating certain parts of the brain and nervous system that are involved in this disease.

Bromocriptine is also used to treat acromegaly (overproduction of growth hormone) and pituitary prolactinomas (tumors of the pituitary gland).

Bromocriptine may also be used for other conditions as determined by your doctor.

Bromocriptine is available only with your doctor's prescription, in the following dosage forms:

Oral
Capsules (U.S. and Canada)
Tablets (U.S. and Canada)

from what i'm reading its used to treat over production of gh not release it
