The fact that you have to ask shows your ignorance. I’m sure all your little 17 year old gym buddies talk about gear and how big they are gonna get, etc. But the reason nobody will support you is because at 17 your T levels are about as high as they are ever going to be and you’re not even finished growing! The only drug you need is fucking food! So you’re 17 and 150 pounds and you want to start gear? Nobody is going to support your decision because you havent put in the time yet, you havent paid your “dues” yet, and you will likely fuck up your endocrine system.
