Bromocriptine gets the job done, but like cabergoline, I've always been concerned about the agonist activity at 5-ht2b. Which can have potentially adverse effects on the cardiovascular system. The one saving grace to this is generally people won't be on either of the meds for long-term. So in hindsight the issues are mostly null and void. But that's why I like lisuride so much, since it doesn't have the same agonist activity at that receptor. Making it more suitable for long-term usage for people who may be trying to shrink a pituitary tumor. Unfortunately it seems next to impossible to acquire outside of Haidut's idealabs. Hope he never quits selling it. I wished someone else had a line or source on some lisuride. I hate only having one source to get something, you never know when they might discontinue the product.
