I see a fair few posts on these forums about supplements, mostly what works and what doesn't work etc etc and I'm going too try knock it out for anyone here thinking about starting to go to the gym and wondering what to spend they're money on.
I'll start off by saying you DO NOT NEED supplements to get into shape and build muscle but this is a guide should a person choose to, so please keep the flaming of people's decisions to use them to a minimum.
These products WILL definitely help you build muscle if used corectly
Creatine
There is many different creatines on the market but the only type you should bother looking at buying (IMO) is Creapure Creatine Monohydrate. This is the highest standard creatine on the market and the only one worth your money. Now when first starting it you SHOULD load it for the first 5-7 days of the cycle, this means u take in roughly 20 grams of creatine spread throughout 4 different servings either mixed with water before you eat a meal (there is no need to have it with a fruit juice or anything that spkies your insulin as others may tell you) or with a protein shake if you chose and then continue taking 5-10 grams a day for the rest of the cycle(even days you do not workout) depending on our weight. Now I know alot of people will also tell you the loading phase is just a sales tactic used to get you to buy more creatine but I have personally tried it both ways and the loading phase definatly gets me results faster, yes I still see results when I do not load creatine but not as fast as when I do. In regard to how long you should stay on creatine I personally only take it when I'm bulking, not cutting/maintaining my weight over summer as you are not increasing your muscle mass over this period so I do not see the point in taking a supplement that is designed to build muscle not maintain/preserve it. I also do not recommend taking this supplement if you have a history of kidney problems as it can be harsh on said people, if you are thinking of trying this seek a doctors advice, if you have no history of kidney problems you should be fine using this supplement.
Pre Workouts
Pre workouts are great for giving you an energy and focus boost before you hit the gym especially after a long day at the office. These products are filled with stimulants such as caffeine, beta alanine, and many more and are designed to give you a massive pick me up and if you buy the right ones they definitely will. When it comes to supplementing these I do not take them before every workout, usually only legs and chest/back day(the larger muscle groups) and days when I'm feeling a bit tired, because if you do you run the risk of your body becoming immune to the effects if taken to frequently, I also suggest a period of up too 3months a year when you do not take any of these at all to avoid this as well but that's just personal preference.
Optional supplements that can help if you are very busy
Protein Powders
Now protein powder is NOT a miracle supplement like many gym newbies are lead to believe. When it comes to body composition the protein in powders will not give you any sort of bigger and better gains then chicken/beef/eggs etc etc. However, it is a very convenient ready to go protein source.
In regards to what type of protein to buy there will be 2 major types, whey and casein. Casein protein is marketed as "slow digesting" protein and keeps you from going "catabolic" in between meals and before bed and that it is also much thicker then standard whey protein thus keeping you fuller. Now this is partly true as it is alot thicker then whey and does keep you more full between meals, however in regards to the prevention of "catabolism" it is complete BS as the body does not go catabolic for atleast 2 days of malnutrionment, not 3 hrs (it is also worth noting here that splitting your macros between 6 small meals a day will have no effect on body composition in the long run, you can eat all your macros in 2 servings or 8 servings throughout the day and your results will be the same its all personal preference).
Now good old standard whey protein is the most common and what I recommend you buy IF you choose to supplement protein powder. Whey is usually (atleast where i live) about $20-$30 cheaper then casein protein and will give you the exact same results. The only downside to whey is that it is alot faster digesting then casein and may not keep you as full as casein will but personally I do not think the extra money is worth it. So it's really just a personal preference but I do recommend whey over casein unless you are one of the people who A) aren't filled up enough by whey and B) are willing to pay the extra cash for casein. Also please remember this is only if YOU chose to supplement protein powders, you can get the exact same results without protein powder just eating protein from whole food sources it will have no bearing if you go down that road instead.
Fish Oils, Dextrose, Maltodextrin, Waximaize
These are basically the protein powder equivalent of carbs/healthy fats. You do not need to buy these supplements as you can very easily get the carbs and fats from your diet, and they will NOT give you any better results then whole foods, but just like protein powder they are very easy ready to go sources of their respective areas that can help you if your lifestyle is busy and your struggling to get your daily caloric needs in to the build muscle.
Testosterone Booster
Now legal test boosters are only beneficial should you need them. I DO NOT recommend someone like myself who is in their early twenties to go out and get a test booster unless a medical professional has advised you your T is low, we simply do not need them as our bodies are producing more then enough. However if you are a person in their mid to late thirties and older who is looking to get into shape and build a solid physique these can help you as obviously when you get older alot of peoples bodies produce less T, however even if you fall into this category I would still recommend you seek professional medical advice before taking any sort of test booster.
All the other BS
If there is any other supplement someone is trying to push on you, namely Glutamine, any sort of Amino Acid, Multivitamins and anything that isn't listed above, it's a load of BS, they will not help you build muscle and definitely not worth your money. Most of these other products have apparent studies that show their benefits but all this stuff you get in your diet easily, doubling up on it will not cause double the gains it will just go down the toilet.
I hope this wall of text helps some people out.
