please do not steer me to sarms, I know I respect a lot of you who push them but in my case I'm looking to strictly stick to steroids for now. I am going to be competing in Iron Man type activities and doing triathlons in that sort of thing. I plan on using a test base of 200 mg per week and I would like to do a 12-week cycle, something that will help boost my endurance. What do you recommend?
