WOW !!!! what else can be said????
19- way too young for one cycle let alone 3
HOW TALL ARE YOU??? I hope you are 4'6" tall, cause anything taller and you do NOT have a clue how to eat to grow so steroids are NOT the answer for you right now
16 weeks of deca and test??? you obviously have no clue how to run compounds as 16 weeks is way to long for you and deca needs to be cut short a week or two from the test depending on which test you use.
Do you know what PCT IS??? if not, STOP, do not pass go, do not get another erection for the rest of your life.
What were your other cycles?
Please stop and research before you consider damaging your body further
