When you supplement with Dbol, and this goes for all anabolic steroids it is imperative you live a healthy lifestyle that promotes the continuation of good health. If your blood pressure and cholesterol levels are healthy prior to supplementation, and you shouldn't be supplementing otherwise, continue to live in a way that promotes the continuation of such healthy levels; in-fact, give it more attention. This should not be all that hard to do; after all, you're supplementing for the purpose of performance enhancement, and an unhealthy lifestyle does not promote this end. You bet, this means avoiding excess or heavy alcohol consumption, but it also needs to be avoided due to the C17-aa nature of this steroid as discussed above. Heavy alcohol consumption is extremely hard on the liver, and you don't need the added stress; more so, alcohol itself is the most anti-performance thing you could ever put into your body. While you should avoid excess alcohol, and all alcohol if you want to do things right, you are also encouraged to avoid all over the counter (OTC) medications when possible. Many OTC meds carry extremely strong hepatotoxic natures, some even more so than many anabolic steroids, and their use must be limited to only when truly needed.
The ONLY purpose of the parathyroid glands is to regulate the calcium level in our bodies within a very narrow range so that the nervous and muscular systems can function properly. This is all they do. They measure the amount of calcium in the blood every minute of every day... and if the calcium levels go down a little bit, the parathyroid glands recognize it and make parathyroid hormone (PTH) which goes to the bones and takes some calcium out (makes a withdrawal from the calcium vault) and puts it into the blood. When the calcium in the blood is high enough, then the parathyroids shut down and stop making PTH.
