well you know how everybody and their mom complained about the pain of T-400. well i used it and yes it does hurt but i also was using deca when i took t-400 i took the deca with it and there was zero pain with the injection. and also what was said above it cuts down on number of injections
Less injections and for me it's easier to keep track of what goes in on what days. I preload all the syringes for 8 weeks and then seperate them by content so I know to use X on an even day and Y on an odd day of the month. Yeah Yeah I know, but it works for me.
