Your first cycle should be 500 mg's of injectable Test E or Sustanon per week for 12 weeks.
Actually I think 16 would be better. I'm 25 and did my first cycle earlier this year for 12 weeks with 500 mg test per week for 12 weeks. If I could do it over again....I would have done it an extra month at 16 weeks. I takes about a month for the muscle building to start with Test E, so the second month is realy the first month the real muscle building starts, and the third month you realy start to see the results, then to just stop there sucks! Then again....you don't want to be on a realy long cycle. That's not wise or recommended, especially for a first cycle. That's why I think 16 weeks or 4 months is perfect. That's what I'm doing for my second cycle.
P.S.
The needle and injecting part.....is the easiest part of doing ASS.....you won't feel anything and is totaly safe if you have human grade gear, and clean supplies. The actual shot is painless, put the first couple times you might be a little sore the next mornin and last a couple days...then it normaly stops
The hard part is perfecting the diet, and being disciplined to stick with it. Also Perfecting the right combination of Anti-Estrogens and PCT products that work well for you, and learning to time the your PCT right.
The injections are the easy part and actually pretty exciting.....nothing got my addreneline flowing like it did before my first injection.....except the first time I got pussy
