All guys are right, I would add a little more things as well:
The most 10 to do:
1- Consume at least 500mg of Vitamin C 3times daily
(for reducing Cortisol level, water retention, blood pressure and as an anti-oxidant)
2- Comsume a great amount of healthy fats
(Omega-6 & omega-3 fatty acids contribute to a complex web of biochemical reactions that produce hormonelike substances called prostaglandins. which cause an elavation for Insulin, Growth hormone and preserve Glutamine)
3- Use heavy weights
(Muscles respond to overload, and the most effective way to overload a muscle and stimulate growth is by lifting heavy weights - but overloading muscles off roids may contribute to over-training therefor overloading muscles during Steroids usage is the preferable)
4- Train for no more than 90Minutes under any condition
( As long as Anabolic Steroids works as an Anti-catabolic agents but Training for more than 90Minutes will leads to the elavation of Cortisol(catabolic hormone), decrease Growth hormone & Glutamine level(anti-catabolic substance)
5- Consume a lot of Carbs at least 3grams/bodyweight
(Beside a natural fuel source, In causing the secretion of insulin, carbohydrates can also increase the uptake of amino acids into muscle and enhance protein synthesis- and if Carbs didn't consume the body will use Protein for energy rather than Carbs
6- Consume at least 6-7meals a day
( consuming more meals will leads to higher metabolism, Protein synthesis and healhy digestion)
7- Consume a lot of water
( Keeping well-hydrated at all times is absolutely critical for bodybuilders. When water levels drop in your body, the first tissue to supply water to maintain various metabolic and physical needs (such as cooling the body) is--you guessed it--muscle! A dehydrated muscle is a catabolic muscle. Alternatively, a well-hydrated muscle is an anabolic muscle. and the Myth about drink less water to get less water retention is absolutely wrong at least too much water will deplet Sodium and other salts at the body(kidney & else) and will cause a signified decreasing in water retention)
8- Consume a lot of Fiber
(Fiber is important for optimizing digestion, absorption and overall gut health. We also believe that fiber helps significantly in keeping individuals “dry”--looking leaner and harder)
9- Consume a daily multi Vitamins/Minerals
( With no reason that's essential)
10- Use Creatine Monohydrate
( I can't see anyreason for why everybody says Creatine is a waste of time during Steroids and will hurt the kidney
, Creatine showed not to cause Kidney damage, at least Creatine will replenish adenosine triphosphate, the main source of fuel for weight training, Elevated levels of creatine in muscle cells can stimulate protein synthesis, during Steroids you'll have a better chance to get Creatine's effects, as most Steroids increase Insulin Synthesis & allow the body to produce/accept more Insulin)
11- Consume enough Potassium:
(Potassium is an important electrolyte found within muscle cells and works closely with sodium to regulate body water levels. As well, Potassium plays a critical role in facilitating the electrical potentials across nerve and muscle cells that result in muscle contraction. Potassium is even involved in glycogen storage (for high intensity muscular energy). A poor potassium / sodium balance can lead to improper fluid levels, dehydration, muscle cramps and weakness. Fortunately, dietary intake of potassium is generally not a problem for most people, but bodybuilders should become familiar with its role and the foods where it can be found.
12- Consume enough Sodium:
(As most bodybuilders know, Sodium is an electrolyte that plays a vital role in the regulation of body fluids. The level of sodium in the body determines the amount of water the body will 'hold', and high intakes can cause body tissues to swell. (It is not uncommon to look like 'Quasibloato' and be up to two pounds heavier the morning after scarfing down a Big Mac and large fries.) Although a normal diet usually contains a reasonable amount of sodium, be careful not to limit sodium intake too much at contest time to get an ultra shredded look. An excessively low sodium intake turns on protective mechanisms within the body that cause sodium and water retention. Finally, keep in mind that sodium plays a major role in resistance training; its function in nerve impulse transmission and muscular contraction is critical to bodybuilders. Dietary sodium isn't all that bad, it's having the right amount that's important.
13- Consume enough Magnesium:
(Magnesium's role in bodybuilding revolves around energy production and protein synthesis. Studies on many different types of athletes have revealed excessive magnesium losses in sweat. Unfortunately, bodybuilders probably don't make up for these losses in their diets, as many food high in magnesium (nuts, legumes, etc) do not typically top a bodybuilder's grocery list. [/soze]
14- Consume enough Vitamin B12:
(Although the functions of vitamin B12 are numerous, those important to bodybuilders include carbohydrate metabolism and maintenance of nervous system tissue (the spinal cord and nerves that carry signals from the brain to muscle tissues). Stimulation of muscles via nerves is a critical step in the contraction, coordination and growth of muscles.)
15- Consume enough Vitamin E:
(Vitamin E is a powerful antioxidant, meaning it protects the cell's membranes. This is important because many of the metabolic processes that take place in the body, including the recuperation and growth of muscle cells, are dependent upon health cell membranes, it help to reduce the number of free radicals in the body. Free radicals are natural byproducts of cellular respiration, but accumulation of free radicals can lead to cellular changes and destruction (even cancer), rendering cells unable to adapt normally. This means a reduction in exercise induced processes in the cell such as repair and growth.
16- Consume enough Vitamin B6:
(Vitamin B6 works for Protein metabolism, growth and carbohydrate utilization are all made possible in part by the presence of vitamin B6. Like Thiamine, studies on Pyridoxine in athletic performance show a definite increased need for athletes and possible performance enhancement from supplementation.
