Skeletal Balm from Needtobuildmuscle.com .
Seriously, i get sharp pains in my shoulders from time to time that wont go away for days. I put this stuff on and they feel good in about 20 - 30 mins.
Ive been putting it on pre/post workout and in the evening and it's been working wonders.. I might actually be able to build my shoulders up now, lol.
