I'm a Cat 1 and understand your concern. I've been running T and HGH for 6 weeks and have gained 10# of muscle. Recovery and watts are through the roof though. I'm really concerned about the weight gain...but at this point in the off season, it's worth it. I fired up some GW last Friday for a training camp and my performance was off the hook. People will know you are up to something...so be careful.
