I did a light cycle consisting of primo/var when I had just turned 20. I don't regret it at all, because with proper PCT I kept about 7 lbs of lean on a 6 weeker. I've been training naturally for the past 6 months since then and I was going to do a test cycle but against the better reccommendation of the people on these boards, I've decided to go natural for a few more months and just get to learn my body better. At this age I'll probably stick to light cycles consisting of eq, primo, or var--I figure I'm in this for the long haul, and although I want to compete nationally eventually, I also want to have kids and not suffer long term sides from premature ass use, and I know It's going to be a long haul ~10 yrs or so probably untill I have the mass and muscle maturity to do so.
Good luck on your cycle man, sounds like you've got things in check. Tear it up in the gym and in the kitchen.
Peace
