I realize this is an old post, but I'm curious about this issue now myself. My VA clinic did my annual lab work a two weeks ago and my CPK was 7500. The doc flipped out and was asking me if I'd been experiencing heart attack symptoms. They've retested and had me take an abdomen ultrasound. Don't know results yet on these lastest tests.
I finished an 8 week test-e cycle about 8 weeks ago, did a PCT, and have been cruising on a prescription BHRT cream these past 8 weeks as well. I've reduced protein intake to around 1g per lean body weight and have cut my hi volume lifting in half. I work major muscle groups once/week and do eliptical, biking, and hiking for general cardio.
I actually feel fine other than my muscles being sore a lot more than I recall in my youthful years. The day after I can hardly move which ever group I worked the day before! Also my gains have been reduced significantly.
