This is a very broad question but ultimately most men will be focused on increasing lean muscle. So supplements to help aid in that are going to be the most necessary.
I also would recommend supplements that are tested and true and not products that are new and trendy.
Good nutrition is the number one factor for anything anyone wants so if your nutrition lacks then a meal replacement protein powder or bar is a great supplement to use. In addition to meal replacements creatine, glutamine and NO products are very effective for helping aid in recovery from exercise which will make each any every workout more productive with increases in strength and lean muscle.
If you are wanting to increase testosterone production I would recommend ZMA (zinc and magnesium) which has been shown to naturally improve recovery and testosterone production.
I also believe in a multi vitamin because a balanced diet just does not supply all your vitamin and mineral needs.
I also believe all people should take a good antioxidant. When you train hard, your body need to fight against free radicals and oxidative damage. A good antioxidant is one of the very best way to fight against this and recover more easily from exercise.
If you are interested in fat loss I recommend non-thermogenic fat immobilizers that do not make you burn more calories but rather make sure the calories you are burning are being taken from from and not muscle.
Supplements are what they say they are, (a supplement to your diet.)
Make the a majority of your progress with your diet and exercise and if your habits are good then incorporate a few supplements which can help assist you.
