I currently have a vial of deca and a vial of test cyp. I need to know how much of each i need to take a week and how many times a week i need to take them. I am currently pretty new at taking steroids. I am on a very strict diet and workout daily. I am 20 years old and weigh only 165 lbs. I am 6'0 tall. I can not put on any mucsle size and i rarely gain much strength. i have been reading up on the two and it seems that deca is a good beginners steroid. Is this true? Should i take both or just one. I need HELP?
