Suppression of Lactation:
When the mother chooses not to breast feed or the baby is lost, suppression of lactation may be required. Initially the breasts get engorged, however in the absence of suckling further milk production stops on its own. Firm support to the breasts is helpful in reducing the discomfort. Manual expression is not very helpful as it promotes further milk secretion. Estrogens in high doses can suppress lactation, however there are side effects and the risk of venous thrombosis, hence these are not recommended. Bromocryptine, a dopamine agonist, given 2.5 mg twice a day for 14 days can suppress lactation by producing a fall in prolactin levels. This therapy is expensive, has side effects and there may be rebound lactation once the drug is stopped. FDA no longer approves it. Pyridoxine ***8211; Vitamin B6, given 200 mg three times a day for 5-7 days is quite effective in suppressing lactation and the drug has no side effects.
================================================
Got Wood? note : adding Bromo to your cycle only adds to the potential anabolic cascade, and potentially negative drug interactions. In medicine B6 is supposed to be as effective as Bromo. Plus vitamin B6 has few side effects.
Here are a few of many studies supporting the use of Vitamin B6 in reducing prolactin:

Effect of pyridoxine on human hypophyseal trophic hormone release: a possible stimulation of hypothalamic dopaminergic pathway.
Delitala G, Masala A, Alagna S, Devilla L.
A single dose of pyridoxine (300 mg iv) produced significant rises in peak levels of immunoreactive growth hormone GH and significant decrease of plasma prolactin PRL in 8 hospitalized healthy subjects. Serum glucose, luteinizing hormone LH, follicle stimulating hormone FSH and thyrotropin TSH were not altered significantly. In addition, in 5 acromegalic patients who were studied with both L-dopa and pyridoxine, inhibition of GH secretion followed either agent in a similar pattern. These data suggest a hypothalamic dopaminergic effect of pyridoxine.

[Influence of administration of pyridoxine on circadian rhythm of plasma ACTH, cortisol prolactin and somatotropin in normal subjects]
[Article in Italian]
Barletta C, Sellini M, Bartoli A, Bigi C, Buzzetti R, Giovannini C.
The influence of vitamin B6 in a dosage of 300 mg X 2 in 24 hrs, on circadian rhythm of plasmatic ACTH, cortisol, prolactin and somatotropin have been studied in 10 normal women. After vitamin B6 24 hrs pattern of ACTH and cortisol is unchanged; prolactin levels are slightly lower, in a statistically unsignificant proportion the night peak of growth hormone is higher in a statistically significant proportion (p. 0.05). The effect of vitamin B6 is likely to me mediated by dopaminergic receptors at hypothalamic level as previous studies by other Authors appear to prove.
