Yes it is safe for your age, I have read several positive posts on BBing.com from 50 and 60 + ages. As far as sides for the "older" age groups there seems to be more joint soreness, sleeplessness, and lower back pain due to extreme lower back pumps. For sleeplessness I suggest melatonin, back pumps bananas and painkillers. If you take SD I suggest you ease your body into it start out with 10mg for a few days at least then decide if your body is making some changes and if you want to up the dose. Many people find the best gains between end of week 1 through 3 1/2 weeks, much longer might result in serious natural shutdown ofcourse depending on dosage and personal sensitivity. Have your pct planned and available before you start.Good luck.
