Sorry, but the title says "light cycle" but then you go and say that you "wan't to see results fast" and "what is the most effective?" Light cycles can make good or even drastic changes to someone who responds well to gear and already has a good body. But a light cycle won't give you results fast or be the most effective, that simply doesn't make sense. You need to read about this subject much more. But i'll throw you a bone, keep it simple and start with 500mg of test weekly either c, e, or sust split into two shots, say monday/thurday for 12 weeks. That's a very simple cycle and gives you a starting point as far as the future goes. If you do tons of different drugs on your first go you won't know what does what. As for your PCT (Post cycle therapy) two weeks after your last injection, start using Clomid at 50 mg daily for three weeks or Nolvadex at 20 mg daily for the same.
