100mgs per week subcutaneous into skin on glutes or upper thigh been doing it for over ten years off and on now, you guys are crazy IM low dose its not needed your just injuring your old muscles. Works a treat if I told you my stats you would accuse me of lying so I wont. you can hold plenty with TRT you just can't get full hard and contest lean, but you can hold good size and shape, with abs all day, you just wont get that androgenic fullness or hardness that comes from high androgens that's not TRT.
