First of all, Genetics plays a huge role in determining your Testosterone Levels , and this limits the range of your testosterone levels to a certain point but Don't fear , there are some effective ways to spike up your testosterone levels  so let's begin :

- Diet :

 -Zinc is an important mineral for proper androgen secretion focus on foods such: spinach  ,oysters , liver , and you can try some chocolate from time to time
 -Time to snack ? have some nuts , delicious , cheap and loaded with countless benefits .
 -Don't be afraid of fats , in fact, testosterone is produced from cholesterol so having the right amount of daily fats isn't a bad idea after all..  (see 'how to balance your daily meals' ) 
 -Limit your sugar intake

- Get Some Sunlight :

Vitamin D is crucial for proper body function , it has been shown that a lack of vitamin D will reduce testosterone production , A great way to do this is either by sunbathing or supplementing ...

- High-Intensity Exercise : 

That's pretty obvious ! Exercise helps the body release more testosterone in order to build better muscular mass , but I insist on doing the right kind of exercise such as weight lifting , Sprint ,Squat...
Short and explosive exercises are very recommended by doctors and fitness trainers ..

- Forget Androgen Supplements :

Your testosterone body don't go up for a reason ! when your body spots an abnormal rise in testosterone it will inhibit further testosterone production and thus your genitals start to shrink , thus you may lose your potential and become impotent as well as your risks to have genital abnormalities will increase radically .

 
- Have More Sex Instead :

This will release tension and increase your testosterone levels , also, it's rewarding to the brain , safe ,natural and healthy

- Get Enough Sleep:

Try 7 to 8 hours per day this is the optimal duration , any less of further will damage your body and reduce your effectiveness ..  

- Reduce Stress :

Cortisol is your worst enemy , try to meditate from time to time , have a great laugh , dance and show love to those you love you . the key point here is to find peace within ...

- And Finally Scream As Hard As You Can : 

I'm really not joking ! screaming out loud is a proven and effective way , why ? because it's a placebo effect on your mood . Like a Gorilla ,You will feel more powerful , dangerous and confident after a scream and this is because your testosterone levels increase and your cortisol decrease .
