I never thought I would ever stick a
needle in my bicep until I decided to try
Syntherol. After trying it I was surprised at how easy and painless it was. Use 25ga 1" and just start out with 1cc per head to get used to it. It definitely will give use more places to inject than the glutes, quads, and delts. If you do bi's or any other small muscles get a bottle or 2 of
Syntherol and make those site injections count. You won't be disappointed. PB
