i want to make sure i have this wright. deca the magic number is day four i have heard to take your shot. so should i take 1.5 cc every 4 days? and the test stays in you for 8 days. so should i take the test every 8th day 1.5cc. i have been told 3.5 days but that seems to close. not sure if i should take both every 5th day.
