For your goals, I would recommend HGH or GH boosting peptides (GHRP + mod GRF [1-29]). The one in bold is crucial to the stack and the reason why you didn't get results from the GHRP by itself.
The IGF-1 produced from GH will repair any injury better than AAS, and it is safer and doesn't require any support supplements.
Let me know if you want some more info on this, particularly the legal peptides, since there is already plenty of info available on synthetic HGH.
