Hey Guys, I had a quick question that I've been pondering about for quite awhile, I've never injected juice nor plan to for quite awhile but was wondering if there were any supplements I could perhaps "practice" with...if that makes sense...Yea, kinda a weird question, I've heard B-12 injectable is pretty steller yet I've only seen vetinary grade, so can anyone help a brotha out? hehe, thanks.![]()
