Hey guys battling with a Tendonitis injury in my left arm. Desperately wanting to get back into the gym

Going to be running

2iu gh ED
1iu Igf-1 ED

(Not sure of the length, just see how my injury goes)

Question is whats better Spot injection (IM) or SUB Q for my injury...??

Also if anyone has had similiar injurys and used gh or igf-1 please chime in with your results and what you found worked best.

Thanks in advance
