1 - Cut your shots 50:50 with sterile oil (I have ordered some grape seed oil for this). If you want to use 50mg of Testosterone Propionate, and you have 100mg/mL Testosterone Propionate- pull of your test prop, and of sterile filtered oil to shoot 1mL of 50mg/mL Testosterone Propionate. (I have read many different opinions on the ratio to use but this one make more sense to me, comments welcome)
2 - Heat your gear. i recommend using a heating pad because it can be used to heat the injection site as well. (BE CAREFUL THOUGH TO NOT HEAT YOUR GEAR TOO MUCH BECAUSE YOU CAN BURN YOUR MUSCLE AND THAT WILL BE MORE PAIN THAN YOU WERE TRYING TO AVOID IN THE FIRST PLACE)
3 - Inject slowly.
4 - Exercise will increase blood flow and essentially help absorption.
