Ive been using prop for the first time as a single ester ed for the past 6 days. Last night I felt my arm getting sore just down from my injection site on my delt on my left arm. Today after my workout I noticed red splotches on both my arms and they were my last two shots is this normal, or maybe need to go deeper Im using a 1" pin or maybe my body trying to reject the prop. Any advice would be helpful
