Hi there. I have got a pec major injury and was thinking about taking tb500, tbc 157 or both. But my question is, where should I inject it? Should i inject the insulin needle directly to the pec? intramuscularly or subcutaneously into the pec with the insulin needle? I am new to TB500 and TBC 157 and I can't find a lot information about injectin on the internet so your help would really be appreciated!
