I am very interested in the dbol/drol combo. I have not used it yet. I have used the TNe/dbol and the straight Dbol inject. Both of them were great. Dbol is probably my favorite go-to oral and Geneza Methan10's are what I have been using for the past few years. The new injectable is great though and I think I like it more. I felt it was stronger and had little to no effect on my appetite. The dbol/drol combo packs a lot of hormone of two very powerful steroids, in each cc. I would start out with 1/2cc ED for a couple of wks and see how you respond. If you feel good and want to go higher, I wouldn't go past 1cc. The injectable dbol felt much stronger than the oral. If I were to guess, I'd say 30% stronger. 

One thing i will note...I thought that the 50mg dbol shot might have some preworkout benefits, but I didnt seem to notice any. Maybe I got better pumps in the first couple of days. Maybe it was in my head. After a wk to 10 days though, I was in for a wild ride. I made some great gains on that cycle
