OK, here's my final post on this subject. My cardio and weightlifting had increased by about 20% and I'm about a week or so since stopping and holding at about 15% of the gains. My resting heart rate is in the high 40's and low 50's. My mile time is under 4:30, my BP is normal for me (120/70) My weight is holding steady at 184 and below. I'm holding at 7% body fat, though I was down to 5%. I felt like I had no energy at 5% but I sure did look OK. Wife loves the new bod, and the sex hasn't been affected negatively in any way. I just hope I can hold the gains, without having to cycle back on. I may cycle in a month or so, but I'm going to look around for a good source, where you can get more than 5 mg in a vial. You need about 100 - 200 mg's per day and the rat studies did 2 - 5 mg per kg. If anyone knows of a decent source for this stuff, I'd be most appreciative of the PM. If anyone has any questions, feel free to shoot em to me, and I'll do my best to get back to you.
