what are your thoughts on injectable b vitamins?

[mr_ectomorph]

Hello everyone. I was looking for a way to combat legarthy. B vitamins came up. However, I was intrigued by injectable b vitamins. What is the purpose of injectable b vitamins (pros and cons)? I have heard people recommending b12 alone and other people recommending b complex.
Is this stuff legal? And where would you inject it (IM or subq)?

Any input would be very helpful
