Im 47 yo and I just started trt 4 weeks ago 200mg.test Cyp per week. My test level before treatment was 201 so Im already feeling better more energy, libido...ect. I have been working out for 25 years and never could get muscle gains until now. I have gained about 8 pounds and have been doing great in the gym, My question is How big can you get from 200mg of Cyp per week? I know most of you guys run a lot more than that, any idea on what kind of gains I can expect?
