I am 22 years old, 254 lbs. 18.4% body fat, and 207 lbs of lean mass and I am wanting to gain some serious mass, anyways I am wondering what would be the best steroid to use, if i can use just a single one, or should I stack them and which ones. and also I have high blood pressure already so I am wondering how high it actually raises your blood pressure? Thank you for your help.
