Just did second injection of test prop for the first time ever... I feel like some one hit me with a pipe the next day! My buddy makes his own and has been for 30 years he made a care package for me to get started for 5 week. I'm doing 300 a week 100 every other day. Is it normal for it to hurt? He said it is because it is new to my body.. any info will be appreciated. Thanks brothers and sisters!!
