One thing I just can't find is any report of how fast the reduction in T with MPA vs Lupron. There are many charts showing Lupron day by day levels but nothing on Depo-Provera. Can anyone tell me how long to get your T to castrate level using Depo-Provera?

Having used it a few years ago, DP takes a few weeks to show much effect, and then again to wear off. Not sure about the hormone levels but it's slow acting in terms of the effects you feel.
