chasingthewinter, I'm in a fairly similar boat to you diet/training wise, and i had been looking at a lot of this stuff in past weeks. from what i gather, the best way to start off is with a test e cycle, running about 500mg/week for around 12 weeks. i suppose you could run you test p and pin EOD, but you would want to become familiar with a lot of injection sites to avoid the weird bubbly things under your skin i've read about. ideally, you should run some hcg along with it and continuing for 2 weeks after to help prevent atrophy (the two weeks being the halflife of test e) and adex to avoid aromatisation, then start with your pct.
clomid and nolva are generally used for female infertility and the prevention of growth of breast cancer cells, so i don't see you getting the legit (though i could be wrong).
as test is quite androgenic, it can have a fairly significant effect on estrogen levels and water retention. the adex will help with this. running clen for maybe the last 4-6 weeks of the cycle could help with bf, but it's pretty harsh on your liver so i really only would take it for the short end. i'm not sure how well a good diuretic, or even some dandelion root tea, after your cycle has finished would go, but it might be worth a look?
i definitely agree with gruf though, nutrition is a MUST! getting it right is the most important thing to continue to improve your physique. get it super tight and have your training awesome, otherwise you'll never get the best results from your gear. it'll also give you time to keep doing some research. i wouldn't start pinning anything until i was 110% certain of exactly what to expect along the whole journey.
as for any other advise, i guess it depends on what your goal is at the end of the day. if you want to be a mountain of muscle, tipping the scales at a lean +120kg, then some people would say to make your first cycle count as this is when your body is most receptive. maybe up the amount of test a bit and add in some tren at 50% the amount of the test and see some crazy gains. some hgh peptides might be a good addition if you have some cash to splash, but i don't really know much about them at this point in time. the only thing there is, you never know just how well your body is going to react to anything, so a lot of people will tell you to just run a straight test cycle first. there are LOTS of sources around for good information, so use them.
hope some of that was helpful.
