Taking AAS is a very serious thing and you should plan it carefully before you even start. You admit your training is mediocre at best, so it makes me wonder about your nutrition. Don't even get me started about your age and weight...
Have you ever thought about WHY you want to take steroids?
Since you've fucked up your last PCT (non-existent) your HTPA could still be very shut down.
To answer your questions:
1) Test E takes about 4-5 weeks to kick in. If you front load this could be around 3 weeks (personal experience). So dbol is mostly used for 4 to 6 weeks at a dosage from 20 up to 60mg ED.
2) If you cycle your off time should be: time ON + PCT = time off. This is a general rule.
3) What kind of AI are you using? Do you even have one on hand?
What can I say? You did something stupid.
