There are a few basic rules to this:
1. Have your diet in check.
2. Train hard, but smart. Long enough time spent training will force you to learn to know your body and to what is responds.
3. Rest enough. Your body repairs itself while you sleep.
4. If you have those fundamentals in place, you WILL get results in either direction.
5. Now you can look at chemically enhancing your training results.
6. I have always preferred beginners to stick to an Test Cyp/Enan only cycle - this way you will know after cycle how your body responds to this compound.
7. From here you can start upping the dosages and adding new compounds to the mix one at a time - again, to test your body's response.
8. Always have an Ancillary e.g Aromasin on hand - you never know if you might need it if your body reacts badly to Estrogen.
9. Always have a PCT in place before you even take your first oral or make your first pin for any cycle (
PCT Post Steroid Cycle Therapy - EliteFitness.com Bodybuilding Forums).
10. Listen to what the guys who have been around advise you, their words are filled with research and experience.
Most of the points above are what I consider to be good building blocks as far as AAS are concerned, but, remain my own opinion.
