I like you're attitude.
While you've used these roids recklessly so far,
you seem genuinely interested in learning how to do it right,
and doesn't come with the "I know it all" attitude many have when having used a little AAS.
That deserves respect IMO.
Read the links people posted;
How to execute first cycle and so on.
It take some time, but it's important.
And if there's anything you don't understand then just ask.
Your next cycle will probably consist of the following;
Testosterone enanthate
Arimidex
Hcg
-then finish with PCT (post cycle therapy) to keep your gains and restore your body's production of hormones;
Clomid and nolvadex (is what many go for)
Or alternatively just clomid or nolvadex (I'd go for nolva if solo)
There's also some other options like toremifene.
That's what we call a test only cycle,
but as you see, there's a lot of other drugs involved than testosterone.
These are all there for reducing side effects and keeping gains.
