Currently around 205 lbs. 27 years old and new to steroids. I would like to bulk up from here. My brother is 225 lbs and he is a lot bigger. I would like to get up to close to his weight. I’m currently eating around 3500 calories a day and I plan on increasing it up to 4400. How much testosterone do you recommend? Should I go with 400 mg or should I push it up to 750 mg? And do you like a 10 week cycle or should I push it to 15 weeks?
