Site pinning,T or F?

[Dee312]

Appreciate all the opinions and advice about placing orals under tongue, but does site pinning in areas such as delts, tri's, quads, etc, help those muscles to grow, or should I stick to the backside? Basically, do site injections work? Thanks for your input.

No site injections do not work it is a myth.
But if I were you I would rotate sites just to avoid scar tissue build up.
