Welcome to EF
Great question. We make sure everyone is alright before we help them with a first cycle. If you are worried about your age, bp, chol, etc. then check with the doctor first. we are not doctors, though we can help people that are interested in AAS use if they are healthy adult males (and some females).
If you have had no issues before now, then we can definetly help you out.
The perfect steriod would be what we naturally produce: Testosterone. You will find, as you research, this is the prefect steriod to begin with.
Please help us out before we can evaluate you. Give us some stats, training history, diet. There are plenty of 'verteran' guy on this board that can help you out better than I.
