Ok my main objective is to burn my excess fat, secondary is to bulk up. Here is my stats

Age: 21
Height: 178 cm (5'10)
Weight: 163 lbs
Bf: 19%
Ratio: 14.4kgs fat : 59.6kgs lean mass (according to Healthcentral)
Training exp: 2 years?
Roid/pct exp: ...I am a beginner >.>

Before you say "just fix your diet and work out harder", I have been for a long time with practically no result.

Doesn't matter how much or little I eat, how hard or little i work out, how healthy or fattening my food is... i don't cant seem to gain or lose weight.

Im at a never-ending plateau here which is why Im resorting to steriods. I've done months of research reading for hours everyday but im still got alot of questions here, here is some:

1) I hear Clenbuterol is good for burning excess fat and gaining some muscle, though some say clen has been useless for them. Is there anything better for this?
2) Is it ok to combine Clenbuterol and/or ephedrine with other steriod cycles like deca or dbol simultaneously?
3) Im scared i wont inject myself properly and stuff it up, besides liver toxicity is orals that bad?
4) Which Steriod is most suitable for first timers that still gives decent results (please include which test and anti-oestrogen also please)?

Thank you and sorry if the questions are hella noob >.>
