i just started shooting my test and winny in my shoulders, but my shoulders are killing me cause i got to take like 4-5 shots a week and it doesnt give my shoulders time to heel. Does it make that big of a difference if i shoot in my shoulders compared to my ass, i heard that you get a lot better gains in the shoulder. Is that true, and if i decide to take one in my shouilder and one in my ass, which AS would be better to go where.
