I did not feel like doing much typing, so I copied and pasted the answers to your questions from the First Cycle and PCT Sticky by the great HeavyIron.

Rather than waiting for the side effects of estrogen to present an aromatase inhibitor like Arimidex or Aromasin should be used on cycle to control Estrogen and keep free testosterone levels high. 0.5mg-1mg Arimidex daily OR 10-25mg Aromasin daily. Start with the lower dose and then see how that controls water retention, blood pressure and libido and make adjustments as needed. A blood test would be the most ideal way to determine the dosage of the AI. Free T needs to be in the high range and estradiol between 10-25 pg/ml.
Human Chorionic Gonadotropin
Testosterone-Induced gonadotropin suppression tends to cause atrophy of the testes and decreases intratesticular testosterone. In other words, when a male administers testosterone his testes shrink because they are suppressed. A simple way to restore ITT levels and maintain the mass of the testes is to administer HCG during testosterone treatment. During a study it was determined that HCG is dose dependant and that approximately 300iu HCG taken every other day restored ITT levels. This is 1,050iu HCG weekly. I recommend 500iu twice weekly while on testosterone treatment. On a very heavy cycle a third dose of 500iu could be added but that is typically not needed. HCG will not only keep ITT levels and the mass of the testes normal but will also aid in keeping the male fertile.
Post Cycle therapy
I strongly believe that an AI should be used as long as there is an aromatizing compound being administered. In this case Testosterone and HCG aromatize therefore using an AI until these meds clear and a few weeks longer is what I am recommending. There is some evidence that adding Nolva to an AI does not increase the effectiveness of estro control therefore Nolva has no real advantage alongside an AI unless one is experiencing gyno. Additionally Nolva has been shown to reduce IGF-1 and GH levels when used alone. This is not a big deal on cycle as testosterone increases IGF-1 in a dose dependant relationship. However off cycle this is a problem. PCT is a fragile time and lower IGF-1 and GH levels is not desirable. I am recommending an AI that is specific to men that can be used on cycle and during PCT. It is my conclusion that Aromasin is the obvious choice.
I recommend the following PCT protocol for esters like Cypionate and Enanthate;
Day 1-16 : 2500iu HCG every other day. (You may use less HCG if your testes are normal in size AND you have been using HCG on cycle, i.e. 1,000iu HCG eod.)
100/100/100/50 Clomid (50mg taken twice per day weeks 1-3)
20mg/20mg/20mg/10mg Aromasin (20mg daily for 3 weeks, 10mg daily in week 4)
3g Vit C every day split in 3 doses
10g creatine daily
The HCG is administered BEFORE the ester clears to increase the mass of the testes and bring back ITT levels. This will allow the testes to sustain output of testosterone sooner.
Clomid is universally accepted as THE testosterone recovery tool. It blocks estrogen from the HPTA and stimulates the production of GNRH then initiates the production of LH, which in turn signals the testis (if not atrophied) to produce testosterone.
Aromasin or a similar aromatase inhibitor is for testosterone recovery and it is used to keep the testosterone/estrogen balance in favor of testosterone. It is also helps to keep any additionally occurring estrogen from HCG low to none.
Cortisol is catabolic. It is the enemy of all anabolism and must be kept in check. While it is blocked when under the influence of AAS, it is free to attach to the Anabolic Receptors (AR) once the steroids leave. Due to this blockage Cortisol tends to accumulate and increase when on. A low level is desirable however since it is important for other vital functions such as control of inflammation. Balance is the key. Vitimin C keeps the exercise induced rise of Cortisol in check.
The use of Creatine has shown to increase ATP metabolism and cellular water storage among many other things. This is beneficial because it provides for heightened nutrient storage and a slight increase in anabolism as well as workout stamina."
