Very bizarre thread overall..
I can't believe this is even a question on Anasci...everyone knows grapefruit extracts increase the biovailability of orals. You don't have to worry about grapefruit extracts with any steroid. It is dangerous in medications that alter heart rate, blood pressure,pain meds etc, etc..because it makes them more potent, and therefore can be fatal.
Many PH's even have grapefruit extracts as delivery systems to make them more effective. It very well can't hurt to take this with your Var.
