i would suggest doing some reserch or how test affects guys that are still produceing hi natural test since u are 20 not that this is the worst thing but just for your own knowledge , and how it will affect your gains and your health .
diet is going to give you 80% of your gains
workount will give you 15%
( i train for 1.5-2hrs a day 6-7 days a week )
if you dont have time to eat properly dont use test it will double your hunger
i would suggest a long ester such as enanthate at a lower dose 350-450mg for 12 weeks pin twice a week.
you wont need to add anything to this just run the test tren is prone to bad side effects and highly not recommended to use on first course
and again do your reserch on your age and the affects , i know once you have a mind set most people just do it but reserch and hard work is the key if you dont no what you are doing and how it works its going to affect your health ,
*****REMEMBER PCT*****
