What are your experiences with Deca/D-bol

I am gathering intelligence and evidence on what your experiences are from a Deca Dianobol cycle . If anyone has been thru this experience would you let me know what gains you made,what if any obstacles you came up against,how it affected and or enhanced your training and for how long including dosages you cycled it for. I would also like to know what D-bol was originally used for as a medication and at what point in the cycle did you intoduce anti est and did you combine clomid and novladex or something else and for what duration?
