So my friend just made a poem, and he's too shy to post it himself, thats why he asked me. :]

Would be cool with perhaps some hints or such to help him get better ;]

I feel it, it's so fantastic
Without no doubt
It's the same feeling as last time
No...
This time it's bigger
I can feel it in my legs
I can feel it in my arms
It's the rush from that
The rush is running through my body
I fucking love it !
It makes me feel alive and happy
It's the biggest rush I've ever had
In my life
and it's name is
Adrenaline

not bad, my only suggestion would be to change
without no doubt -> without a doubt

just sounds better,

Anticlimactic (not always bad, but here it is), typo's here and there, coarse diction at best, and an array of other minuscule things that when combined in poetry make up an arsenal of problems. If a "poet" doesn't know the difference between "it's" and "its" then I doubt he will ever succeed at mastering the language at this time. He needs to read other poetry and the foundations behind it before he tries to make any for other people to read. Or, he can just continue writing his silly feelings on paper, leave the world alone, and live a life of mediocrity.
