I don't want to laugh at you, but you're almost asking for it. You weigh 163, you're 5'7", 19 years old and you want to use AAS. Trust me on this one you're going to do life long damage to your body!

You obviously haven't done all the research you could have done otherwise you wouldn't be asking questions that are answered in these forums a million times over and secondly you would know better than to use AAS at your age read this article I copied from HPs post its the only part you should be concerned with at the moment:

Am I old enough?

Yes if you're over 24, No if you're under. You run the risks of premature closing of growth plates which means you won't get any taller and your shoulders won't get wider, etc. if you use them too young. Your endocrine system is also at a vital stage in your life, which should incidentally provide you with plenty of natural testosterone anyway!

Of course there are other considerations such as training experience of the individual. For example, it would be unwise for a 25 year old who has been training only a few months to want to use steroids. Their training and diet knowledge are likely to be limited (these should be 100% in check to make 'proper use' of a steroid cycle). Not only that, but there will be massive potential for natural gains, without the need to even think about steroids!

Furthermore, cycling before the age of 24-25 will put you at a high risk of temporary to permanent damage to your HPTA, andropause, TRT, erectile dysfunction, and low libido. Your hormones should not be tampered with while still in the stage of maturation. Use your already naturally high test levels to your advantage.

You should have a significant amount of training under your belt (4-5 years at least) before any Steroids are considered. This will not only allow you to toy around with a few diet and training methods (possibly eliminating the reason for cycling in the first place) but will also you adequate time to let your CNS, bones/joints/tendons/muscles to mature so that you will have the proper foundation for when you begin your cycle. Cycling on a frame that is delicate and inexperienced runs many risks including temporary to permanent injury to any of the above mentioned. Bodybuilding isn't a sprint, and there is no rush to jump on steroids and get big. Transforming the body takes time, patience, dedication and discipline. There are no short cuts!

Diet is probably the most important and vital tool is growing and gaining muscle/shedding fat. With a strong diet as your backbone, the steroids will not live up to their hype. No matter what your doses and duration of steroids you are taking, it just won't be worth the time and money spent without the sufficient calories and macros behind it. The 2 literally go hand in hand. A lack of diet will provide a lack of results, even with anabolic support. Having this experience will make cycling in the future easier and much more enjoyable, believe me.
