I have no clue of the extent of your injury and if rehab is possible. If it is, I can suggest some compounds that will aid in speeding up muscle growth, but it of course will not fix the injury itself, if the spine is damaged. I would not suggest taking gear to mask an injury so that you can push through. That's only going to lead to more problems. If you can rehab the back, something like this may help. Do keep in mind that Deca can mask an injury. You will have to be very conservative with your training program and use your head. I'm not putting this cycle together, so that you can try to continue deadlifting.

If you can afford it, GH @ 2iu ED from the start and continue on, at least through PCT. Longer if possible. As I've mentioned before, I would go with whats best, Hyge GH
