Consume 10 to 20 grams of high-quality protein within 30 to 60 minutes of a weights session. Research has shown that an intake of 6 to 12 grams of essential amino acids, which is equivalent to 10 to 20 grams of a complete protein, promotes enhanced muscle recovery and rebuilding after a workout. One gram per kilogram body weight (about 0.5 grams/pound) of carbohydrate taken with the protein may assist this anabolic boost. Some trainers call this a protein "shooter." Options that meet these requirements include 17 fluid ounces of flavored low-fat milk; 1 cup fruit salad with 7 ounces of flavored yogurt; or a large glass of nonfat milk with two slices of bread and honey or jam (no butter).
Creatine is a time tested product important for energy and volumizing—this means it can cause the muscles to swell in size. Many current products revolve around this concept. There are many different types of creatine out there, they all, of course, claim to be the best. I like the original creatine monohydrate by itself, this needs to be mixed with a sugary drink, I use Gatorade.
An obvious one I know, but many misjudge this. If you have two weeks to get ready for the beach then the quickest way to drop fat (and subcutaneous water that can blur muscle definition) is to drop your daily carbohydrate intake to 50 grams of fibrous carbohydrates. So say hello to broccoli, cauliflower and kale, and kiss goodbye to breads, cereals, fruit, rice and pasta. Where people go badly wrong when dropping carbs is that they simply switch to eating lean proteins and don’t replace some of the lost carb calories with calories from fat. This inevitably leads to an energy crash and the subsequent blowing of the diet because the trainee simply runs out of steam and willpower. A few whole eggs, a piece of steak and plenty of supplemental Omega 3s (I prefer 10 grams a day for carbohydrate tolerant individuals, more if there appears to be insulin resistance) work wonders. 
If you've been competing for five-plus years, there is a quiet confidence that comes from knowing what you bring to the table. If it's your first time, don’t allow yourself to get rattled. Nerves cause cortisol to shoot up, which causes water retention and all kinds of other unwanted issues. If you’re well prepared and you have done all the hard work, it's time to enjoy the fruit of your labor.
OK. Imagine this: It's the end of the most intense workout you've ever had. It's gone extremely well up to this point. You just need to bust out one more set of deadlifts and then you can call it a day and relax with a nice protein shake. But when you pull the weight off the floor, it falls back down. You think to yourself what's going on, and that you know your legs have enough energy left to pump out a few more. What's the problem?
Is your resting heart rate jacked up today? Are you too sore from your last workout to walk? Did you only sleep a few hours the last night? Skipped breakfast and lunch? Congrats, you just earned yourself a rest day. In other words - go home. You aren't going to get anything but an increased risk of injury by training in any one of these conditions.
Carbohydrates play an important role for bodybuilders. They give the body energy to deal with the rigors of training and recovery. Carbohydrates also promote secretion of insulin, a hormone enabling cells to get the glucose they need. Insulin also carries amino acids into cells and promotes protein synthesis.[26] Insulin has steroid-like effects in terms of muscle gains.[27] It is impossible to promote protein synthesis without the existence of insulin, which means that without ingesting carbohydrates or protein—which also induces the release of insulin—it is impossible to add muscle mass.[28] Bodybuilders seek out low-glycemic polysaccharides and other slowly digesting carbohydrates, which release energy in a more stable fashion than high-glycemic sugars and starches. This is important as high-glycemic carbohydrates cause a sharp insulin response, which places the body in a state where it is likely to store additional food energy as fat. However, bodybuilders frequently do ingest some quickly digesting sugars (often in form of pure dextrose or maltodextrin) just before, during, and/or just after a workout. This may help to replenish glycogen stored within the muscle, and to stimulate muscle protein synthesis.[29]
