Sorry if this has been asked before...
I am affraid to try this test 400 I just bought....
I always hear people complaining about how bad test 400 hurts, and that you should cut it with b12 or sterile oil...
My question is how much b12 or sterile oil should you add with it, and how much is too much or how much does it actually help the pain? or does b12 take away the pain better than sterile oil?
thank you.
