What was your dosing scheme?I ran a log on another site, but can't post a link, due to being a new guy on here. At any rate, my resting heart rate went from 62 to 48, my cardio output went from about 27 calories per minute to 32 calories per minute. I was able to increase my cardio heart rate from 152 to 176 for a sustained 60 minutes. Not such a high cardio rate, I know, but I am 50, so its decent. My body fat went from 12% to 7% (measured by impedence and calipers)and my weight lifting went up about 20% both in weight used and reps. My timed mile, before was sub 5 minutes, but I got down as low as 4:20, and and during the last couple of weeks, I was able to consistently put in sub 4:30 miles.
The downsides I had, were some issues related to sexual arousal, kind of like what letro does to me. A little cialis and all was well. I also noticed a fluttering in my heart sometimes. I have had that happen years ago, but it returned several times while on GW1516. Overall, my impression is that its like a concentrated winstrol. Maybe 5 times as potent. I liked it, and intend to run it again, if I find myself slipping off of my numbers. The only point I'd make is to start really slow, and work your dosage up, SLOWLY so as not to harm yourself. Who knows, maybe this stuff will make your dick fall off in 5 years.
