Dude listen up. They keep telling you to get to the diet section. What is wrong is exactly what you have said, you have no routine in working out or diet. All the pills, shots in the world wont help you if you dont have a strict diet and routine. This is not magic. The reason most people take steroids or supplements are for all the wrong reasons.
No matter what you take you can not grow without food. You may gain some water weight and bloat but you will loose it as fast as you gained it once you finish your cycle. You need to learn to eat, diet, what to eat and when to eat it. You need to do it regularly for months and years to make a difference. Dont look for changes in weeks or even a month or two. Look for changes 6+ months down the road. Dont be in a rush or you will always be disappointed and fail.
All these guys you see at the gym who are big have years off experience training and good diets eating 2x as much as most people. A good start is eating 6 eggs in the morning with a cup of oats then 2 hrs later 2 chicken breast, boneless, skinless with rice and vegetables as well as 4 more meals per day. Dont trade shakes for real food. Use shakes for post workout recovery but not as food repla***ent.
You need to eat good clean food or you will gain fat also. Drink 1 gal of water a day or more to stay hydrated and keep the bloat down and system clean. This is what you need, not aas.
Why put high octane gas into a stock car or one with high mileage that is worn out? It will only burn out the car engine sooner. Get your body in shape, tune it up and make it so it can actually benefit from the use of aas/high octane gas before wasting your money.
