I've been on trt for a year now and I've been taking 100mg a week which puts me at about 800 total. I'm 37yo 5'8" weigh 200lbs with about 20% bf. last year I started trt at 225lbs and close to 30% bf. I have saved some of my doctor prescribed test cyp for a blast which I plan to do in a few more months. My question is because I'm already injecting 100mg a week will my blast dose of 400mg a week be felt right away or will I still have to wait a few weeks to notice changes on the higher test dose?
